SIEMENS S1000 system maintenance

Failure phenomenon:
Siemens S1000 color super machine, the boot into the ultrasonic working interface is normal, the heart probe is used normally, but the superficial probe and the abdominal probe can only be used normally in the 0B mode, can not be used in other modes, the machine has a card screen phenomenon at the same time.

Failure analysis:
The signal processing and control module of S1000 color supercomputer is mainly composed of probe interface module, input and output module and electronic system module. The electronic system module includes TR, CB, RC, BE, VI and RM board, TR, RC board and probe interface module ( The TI Module) performs the ultrasonic signal processing functions together, collectively referred to as the front end portion; the BE, VI, and RM boards are responsible for the subsequent processing of the ultrasonic signal data and the overall control functions of the machine, collectively referred to as the back end portion. The power supply consists of four sections, an AC AC power box, a PSA analgo power module, a PSD digital power module, and a QuickStart Battery.

Firstly, if the system software error occurs, the fault occurs. After the system is reinstalled, the fault still exists, and the system software fault may be eliminated. The problem of RC and BE is initially judged from the hardware function. As the real-time control board of the front end, the RC board is also responsible for the control function of ultrasonic transmission and reception. It is also responsible for analgo-to-digital conversion of the 192 channels of received data of the TR board, thereby converting the echo signals into digital signals, which is convenient for the back-end software. Further processing of the technology. A failure of the RC board will cause all other functions of the machine to be abnormal. The BE board receives the digitized echo signals from the front RC board and processes them according to the operator's requirements. The failure of the BE board often causes one of the functions of the color Doppler to be abnormal.

The PSA and TI can be considered by the hardware replacement exclusion method to eliminate the BE and RC failures. The TI board can support 3 probes at the same time and can be switched at will, but the probe hot swap is not supported. When the TI board fails, it will cause the 2D area to have no image, card screen or boot code "US_IMG_17" and other error codes. The PSA is responsible for the front end power supply and provides the probe working voltage. If the PSA fault will cause the probe to be caused by the abnormal voltage supply. The function is not working properly.


Repair results:
Replace the PSA power supply, all the functions of the machine are used normally, and the fault is eliminated.

GE VIVID I system maintainance

First, the failure phenomenon:
The machine starts normally, and after receiving the probe, it prompts an error and the probe is not recognized.

Second, the failure analysis:
The ultrasonic probe does not recognize the power supply that normally considers the probe interface board or supplies power to the probe interface board. The machine configuration diagram shows that there is no high-voltage switch on the interface board of the model, that is, it does not affect the high-voltage output of the DC power supply, so it can pass the detection. The DC output voltage directly determines whether there is a fault in the power supply. After the detection, the machine is found to have no high-voltage output, and it is determined that the DC power supply is faulty.

Third, testing and repair:
Replace the DC-DC power supply, the probe can be recognized normally after the machine is started, and each function resumes normal operation.

In genneral, we are really experted in ultrasound repair.

Aloka Alpha 10 system Maintenance

Fault conditions

The ALOKA &α10 machine abdomen probe has no echo, the superficial probe has only a weak echo, and the heart probe has a normal echo.

Failure analysis

Since the heart probe has a normal echo, it is necessary to first eliminate the fault caused by the probe itself, and replace the other abdominal probe for testing. The test result also has no echo, and the fault is determined by the hardware of the machine itself. There is a voltage output indicator on the IO board at the rear of the machine. It is found that the +70V indicator is not lit after the machine is started, and the +90V indicator is always on. +70V, +90V supply the working voltage of the probe to the machine, combined with the echo of the abdomen probe and the normal echo of the heart probe. The fault may be caused by insufficient voltage supply of the high voltage power supply.

Troubleshooting

After replacing the high voltage power supply EU-6031, the machine resumes normal use.

 

Repair Philips CX50 Blue Screen Fault

First, the failure phenomenon:
The machine has a blue screen when it is turned on and cannot be started normally.

Second, the failure analysis:
On-site consultation using the doctor learned that the machine did not make any changes to the machine hardware and software before the blue screen appeared, the blue screen code is 0x000000ED, the code generally points to the hard disk failure. After the machine is disassembled, the hard disk of the machine is detected. It is found that the hard disk has bad sectors, and the bad sectors of the hard disk often cause the hard disk to work normally and affect the startup of the machine. Since the direct repair of bad sectors of the hard disk will result in the loss of data of some sectors of the bad track, an attempt is made to check and repair the data of the hard disk to ensure that the color system software carried in the hard disk can operate normally.

Finally, testing and repair:
Repair the system hard disk and work normally after the machine restart.

Phililps CX30 System Maintenance

The phenomenon of failure:
The system is properly starting-up, but it will crash during use.

Failure analysis:
Crashing is mainly failure of main board, and the stuck interface prompts the discovery of a new keyboard. This may be a system driver failure resulting in incompatibility or a short circuit in the numeric keypad.
Reinstall the system, the fault remains the same, consider the numeric keypad failure, but the same problem occurs when disconnecting it from the control panel. This fault occurs only when users uses panel keys,then it is suspected that there is a short circuit in the control panel part. So it needs further testing.
The ultrasound machinevuses Windows XP system, then using a keyboard test software of the system can accurately detect whether the keyboard has any problems.
Even if the the numeric keypad and the control panel is disconnected, the failure is the same. So it can be determined that the fault is caused by the short circuit of the panel, which continuously triggers the system crash caused by the numeric keypad.

Testing and repair
Replace the control panel and the machine will return to normal.

ALOKA SSD-3500 Fault Repair

1.The fault phenomenon

After closing the switch, ssd-3500 color ultrasound was started. After the "Aloka" sign appeared in the startup process, the blue bar kept moving and the panel light kept shining. The system could not enter the normal ultrasonic diagnosis interface.

2.Failure analysis

When this happens, the first thing to think about is the CPU and HDD issues that are directly related to system startup.Since the machine's data processing platform is based on Microsoft's Windows operating system, just like ordinary computers, the boot process is basically the same.
In addition to the normal CPU and hard disk data reading in the startup process of the ultrasonic device, each image processing board containing flash should be confirmed for data, so as to determine whether there is any data loss or need to update data, so as to brush flash again in the startup process.The indicator light of the hard disk is flashing constantly during the boot process, indicating that the data of the hard disk is read and written constantly and the hard disk is troubleshooting.
Next, unplug and unplug each group of wires. After re-plugging and unplugging, the fault will remain after starting up.If it is suspected to be a CPU fault, take out the CPU board and observe it to see whether there is obvious burning down or insufficient heat dissipation causing component damage. After observation, it is normal.
After the discovery of the motherboard has a button battery, removed from the measurement of only 1.6v.It is inconsistent with the actual mark of 3V, and the voltage value is obviously not enough to support the normal reading and writing of the hardware part of the chip, resulting in problems in the data communication between the CPU and the hard disk, affecting the normal loading and data update of the device.

3.Exclusion and summary

After replacing a standard 3V battery, the device starts normally and enters the ultrasonic diagnosis interface for troubleshooting.
For ssd-3500 color doppler ultrasound startup, the blue bar after the "Aloka" sign& appears in the startup process keeps circulating and the panel light circulates and shines. The system cannot enter the normal ultrasonic diagnosis interface, which basically determines that the components or hard disk on the main board have problems.

ALOKA α5 color doppler ultrasound fault repair case

ALOKA alpha 5 is equipped with advanced front-end technology, original data processing platform,high-capacity digital beam generator (12bit digital beam generator) and other technologies to ensure the high-quality image of all organs in the body.And as well as the varties probes in ALOKA, ALOKA alpha 5 can meet the needs of linical diagnosis and scientific research,At present, ALOKA alpha 5 is used in many hospitals in China. Now we will analyze one of the common faults encountered in the use of ALOKA &α5.

Faults phenomenon

When operating the CW(continuous doppler), the diagnostic instrument crashed with an error prompt, and the other functions were all normal.Error warning: the machine detects abnormal voltage, please restart the system.

Failure analysis

(1)The CW function of the diagnostic instrument can only be used in cardiac, and it has no such function in other conditions, so the CW board may be damaged.
(2) in case the appearance of the fault, the working voltage of CW measured by the attached power box drops significantly, which may be caused by the attached power box.
(3) this fault may also be caused by CW signal and loss of communication function.
(4) the heart probe (phased array probe) is composed of PW and CW, and the heart probe may be damaged.
(5) the software system is damaged, resulting in the loss of CW function.

Troubleshooting

It’s not working after replacing the attached power box and related circuit boards,the dead phenomenon didn&’t appeared when the heart probe was replaced . The problem was e circuits of the machine appeared,the restart of the machine are required.

GE Logiq P6 color ultrasonic fault

1. Faults phenomenon

After reading the tags, you will not be able to enter the operation interface.

2. Faultsanalysis and troubleshooting

The loss of files is usually a system fault, and the system can be restored after reinstallation. According to the customer's feedback, there are important patient information and parameters in the machine. In order to maximize the customer's interests, we try to repair the system.
Since the prompt file is missing, it is theoretically possible to recover the lost or damaged file by filling in the missing or damaged file. At the same time, because the user cannot enter the operation interface normally, the abnormal information should be found through the log file.The operation steps are as follows:

Step 1: according to the prompt path, it can be known that this file is the user's default file. After opening this file, it is known that only some basic information and Settings of the machine are recorded in it, and relevant parameters required for diagnosis are not affected.

Step 2: copy the same file in another system for replacement, connect the machine to start up and use normally, and help the customer to backup the data again.

3.Summary

Color super data should develop the habit of regular backup, so as not to cause unnecessary trouble when failure.

Maintenance of GE LOGIQ P6 Color Doppler

Fault phenomenon

All probes of GE LOGIQ P6 machine have interference in color Doppler mode.

Fault analysis

LOGIQ P6 machine plate structure is simple, plate function integration is high. The color Doppler processing function of the machine is on the SYSCOM motherboard. Generally, this kind of interference is caused by probe failure, external interference or SYSCOM motherboard and APS power supply.
Due to the interference of all probes in the machine, the possibility of failure of all probes is very small, so other probabilities should be considered first. Pushing the machine to another floor room for testing, there are still interference faults to eliminate the possibility of external interference. APS power supply failure may cause interference of machine access voltage. APS power supply failure may be eliminated after replacing the test. Finally, the SYSCOM motherboard was replaced, and the machine started to work normally. All the probes entered the working mode of color Doppler without any interference and troubleshooting.

Summary

GE LOGIQ P6 is easier to maintain than other ultrasonic machines because of its simple plate structure. Maintenance is mainly based on the specific performance of the machine fault and the working principle of the machine to analyze the fault location and take corresponding treatment measures, for the more difficult to analyze and judge the fault location should be carefully and step by step investigation, avoid random attempted maintenance

GE Logiq P9 maintenance 

Fault phenomenon
Dark lines appeared in the ultrasound images. There is a dark line on the ultrasound image of GE Logiq9 color Doppler Ultrasound. There is no echo signal in the dark line area. When the image is formed, the position of the probe is moved, while the position of the dark line is always fixed.

Fault analysis
After scanning the machine probe with the coupling agent, it is found that the edge of the dark line of the
image is obvious. According to the analysis of the principle of the formation of the ultrasound image and the structure of the color Doppler ultrasound, the cause of the failure may be the problem of the corresponding probe wafer or the corresponding channel. Switching different probes for testing, it is found that each probe has the same dark line, and each probe has the possibility of wafer damage at the same time. It can eliminate the damage of the probe, and the failure may occur on the corresponding channel board. There are 8 channel boards in the front end of GE Logiq9 color Doppler Ultrasound. The corresponding ultrasonic transmitting and receiving and A/D conversion are carried out. Eight channel boards correspond to different probe channels. Each board processes 24 channels. Mark the corresponding dark line position, shutdown and switch channel board position on the display image. When switching to the fourth channel board, the corresponding dark line position on the image moves. Then cross-check with another channel board and the fourth channel board to determine that the fault occurs on the fourth channel board.
 
Repairing
The signal processing channel boards of modern high-end color Doppler Ultrasound usually have 2, 4 or even 8 boards. These channel boards are identical. When the image is dark, the positions between the channel boards can be changed. The replacement method is used to achieve the purpose of diagnosis and lock the fault parts accurately. The machine returned to normal after replacing the fourth passage board.

GE LOGIQ P5 Troubleshooting

Failure phenomenon
LOGIQ P5 has no response at start up.

Failure analysis
Switch ON the POWER, turn ON the main switch at the back of the machine, press the "POWER ON" button, the monitor and keyboard lights are off, the cooling fan is not turned, and the machine has no response.POWER ON cannot be activated when the UPS POWER supply and the main switch of the machine are restarted. The output voltage of UPS measured on fieldis 222V,which indicating that the POWER supply is normal.After turning on the main switch of the machine, the waiting light next to the transformer can be seen from the transformer cooling hole below the machine, showing that AC 220V has entered the machine.Press POWER ON at this time, still no response, suspected the machine internal POWER supply (APS) may be faulty.

Troubleshooting
Open the side cover of the machine, observe the APS panel indicator, only the LPS indicator flashes, and the other lights do not works.According to the working principle diagram of APS, LPS is the preparation indicator light of APS, which should be in the long and bright state.Flashing indicates that the machine is in a protected state.Test the voltage at each connection from the motherboard of the machine, and the voltage deviates from the normal value, so that the lock fault is caused by APS's failure to start vibration normally.Replace the APS, and the machine is in normal use.

GE LOGIQ P6 fault repair case 1

Failure phenomenon

All probes on the GE LOGIQ P6 machine interfere with the color Doppler mode of operation.

Failure Analysis and Troubleshooting

LOGIQ P6 machine plate structure is simple, plate function integration is high, the color Doppler processing function of this machine is on SYSCOM motherboard, generally this kind of interference considers the probe itself failure, external interference or SYSCOM motherboard and APS power supply.
Since all probes of the machine have interference, all probes are unlikely to fail, so consider other faults first. Pushing the machine to another floor room for testing still has interference problems and eliminates external interference. APS power failure may cause interference to the machine's access voltage. It may be possible to eliminate the APS power failure after the replacement test. Finally, the SYSCOM motherboard was replaced, the machine started to work normally, and all the probes entered the color Doppler working mode without any interference, and the fault was eliminated.

Hitachi EUB-5500 Maintenance

Failure phenomenon

The machine can't start normally. After booting, the progress bar goes to 1/3 and is executed. After shutting down, the same fault still occurs when the machine restarts.

Fault analysis

Hitachi EUB-5500 starts normally after opening the circuit breaker switch and pressing the boot button, the background indicator light of the control panel lights up, the display displays the reading progress bar, after the reading process of the progress bar is completed, the information that the system is starting will be displayed, and then the "Now setting system data. Please wait" start-up surface will appear, and then the ultrasonic system will enter the freezing state of two-dimensional mode after starting.
When the machine goes to 1/3 of the time bar after booting, it can be inferred that the failure of the machine system or PC part results in the phenomenon of machine crash. Firstly, the machine is rebuilt and then tested. After starting the machine, it shows that the reading progress bar is still 1/3 of the machine dead, eliminating the possibility of machine system failure. Hitachi EUB-5500 machine PC part motherboard, MAP board and PB2 board failures may lead to machine startup crash. After re-plugging the MAP board and PB2 board, start-up test, the same crash failure still occurs, eliminating the possibility of bad plate contact failure.

Troubleshooting

After repalcing the main board one by one, the MAP board, PB2 board and the main board are tested. After replacing the main board, the machine starts up nomally and enters the two-dimensional working interface of ultrasound. The machine restarts several times and runs normally, and the machine troubleshoots are eliminated.

Maintenance Cases of Medison

The fault phenomenon
The color Doppler machine of SONOACE X6 operates normally, but there is no display in the image area after entering the working interface of the ultrasound.

Failure analysis
Remove the SONOACE X6 probe interface board and observe that the internal structure of the machine consists of only three plates, namely FE plate, BE plate and POWER plate. Since the probe has normal working sound after the normal start-up of the machine, and the two probes of the machine have no image display, first of all, the probes interface board and the probes themselves can be eliminated, the machine color mode and PW mode can be turned on, and the image area of the machine can display the working mode normally, eliminating the possibilities of the failure of the back part of the ultrasound, that is, the BE plate. At this time, the faults may concentrate on FE and POWER boards. The function of the front-end part of the machine is focused on FE boards, while POWER boards are responsible for the normal output of each voltage. The same faults still occur when replacing the POWER board testing machine. Finally, the FE board problem is determined.

Testing and repairing:
Replacement of FE board.

Philips CX30 system maintenance 
 
The phenomenon of failure:
 The system is properly starting-up, but it will crash during use.

Failure analysis:
Crashing is mainly failure of main board, and the stuck interface prompts the discovery of a new keyboard. This may be a system driver failure resulting in incompatibility or a short circuit in the numeric keypad.
Reinstall the system, the fault remains the same, consider the numeric keypad failure, but the same problem occurs when disconnecting it from the control panel. This fault occurs only when users uses panel keys, then it is suspected that there is a short circuit in the control panel part. So it needs further testing.
The ultrasound machine uses Windows XP system, then using a keyboard test software of the system can accurately detect whether the keyboard has any problems.
Even if the the numeric keypad and the control panel is disconnected, the failure is the same. So it can be determined that the fault is caused by the short circuit of the panel, which continuously triggers the system crash caused by the numeric keypad.
 
Third, testing and repair
Replace the control panel and the machine will return to normal.

PHILIPS HDI5000 color ultrasonic

The phenomenon of failure:
HDI5000 machine occasionally sends 0002 error when starting up, and there is no echo in the ultrasonic image area when the fault occurs.

Failure analysis:
Detailed information of machine error reporting shows FEC error. According to the list of HDI5000 machine error diagnosis, 0002 represents the front-end plate fault, which may be the fault of PSM power board, AIM board, FEC board or CB board.The reason why the machine has no image display is generally that there is a fault in the high-voltage output of the machine, which is generally caused by the PSM power board or AIM board. After replacing the PSM power board and AIM board, the machine still occasionally reports an error of 0002, and the possibility of failure of the PSM power board and AIM board is excluded.Considering the occasional failure of the machine, the CB board may also be out of order. Since there are 8 CB boards in total, they need to be eliminated one by one. Judging from the logic, if the CB board is still out of order after starting up, the CB board may be out of order.

Testing and repair:
After replacing CB board (A9F), the machine starts up and returns to normal use.

Replace CPU fan and sip, fan temperature returns to normal, troubleshooting.

GE vivid E9 ultrasonic trouble shooting(1)

Fault phenomenon
After power on, the main display indicates that the system cannot be entered, and then there is an error message in the progress bar, indicating that the system needs to be shut down, and then the black screen automatically crashes.

Fault analysis
The vivid E9& host hardware mainly consists of the following four parts:
a. Main power supply: provide power supply for the whole machine;
b. Back end processing system: system control and ultrasonic image processing;
c. Front end processing system: ultrasonic generation and reception;
d. Console: (keyboard, touch screen and display).
According to the fault performance, it is caused by the communication failure of front and rear terminals, and there are several possibilities as follows:
(1) The main board of the host back-end processing system fails;
(2) Output circuit fault of main power supply;
(3) Communication control board failure of front-end processing system;
(4) The front and rear connecting lines are faulty.

Troubleshooting
First of all, start from the simple point: connect the front and rear ends, pull and plug in the fastening connecting lines, and restart can be successful. At the initial stage, I thought that the fault had been solved. As a result, the machine broke down again after several days of use, and the fault was even more serious. After the machine was turned on, the main display had no image display. Check the back-end main board, and the CPU fan stopped running after several times. Make sure that the main board did not get up, check the back-end power indicator, and the input voltage indicator was normal. Based on the previous faults, it is judged that the main board at the back end of the host is faulty.
Replace the main board of the back-end processing system, and solve the problem.

Fault phenomenon
There are no obvious interference or problem images when examining the patient, but occasionally the image will feel like snowflakes drifting, and there will be small areas of snowflake interference when using the keyboard.

Fault analysis&Troubleshooting
First check the keyboard USB input voltage, measure the voltage is normal, there is no obvious voltage change, and the shell is not charged. Test DCDC output voltage is normal. When I checked again, I found that the keyboard popped up not smoothly and smoothly. Raised the console, and found a problem: the ground wire under the keyboard got stuck in the slideway, and it was found that the exposed metal wire of the ground wire touched a metal object, there would be interference. This ground is a protective ground. Grounding is to protect the earth leakage of electrical components when the skin is damaged. It has a certain protective effect.
When the cable was reconnected to the grounding slot, the failure did not occur again.

GE Voluson E8 no display at boot

Fault phenomenon
There is no display after booting, and an error will appear on the touch screen after a period of time.

Fault analysis
The RTV pointed to by the error belongs to the video management board. The failure of this board may indeed cause the machine to boot without display, but the failure remains after the replacement. First eliminate the possibility of the board failure.

The display function of the machine is mainly managed by the graphics card and the RTV board. Observing the output of the PC chassis line shows that after the machine is started, the image signal should be transmitted to the RTV through the graphics card, and then transmitted to the display and touch screen display.

After troubleshooting the RTV board, the graphics card is most likely to fail, and the machine will be accompanied by an alarm sound when the machine is turned on. Generally, this situation occurs only when a hardware failure is detected during the startup of the PC chassis.

After unplugging the video card, connect the DVI image transmission line of the machine directly to the DVI output port of the motherboard. After the machine starts, there is no alarm sound and the display has image display output, so it can be determined that the graphics card is faulty.

Troubleshooting
Replace the video card and the machine resumes normal operation.

Philips IU22 ultrasonic alarm is lifted

Fault phenomenon
The alarm dialog box appears about 10 minutes after the Philips IU22 ultrasound device is started: 
"System temperature alert.The system has reached a crifical temperature limit, and will power down automatically in 30 minutes.Please check the system air filters before contacting TechnicalSupport.Press OK to power down the system immediately. DiagCode:001"
The operating doctor usually clicks the "continue" button to continue to use, but the system will automatically shut down after 30 minutes, and the alarm prompt will continue to appear after restarting.

Fault analysis and Troubleshooting
The alarm is that the internal temperature sensor of the device detects that the temperature is too high, and the information of the operator of the device is fed back through the computer, and the device protects itself. The possible causes of such failures are clogged air filters, aging or damaged cooling fans, and temperature sensor failures, among which the probability of failure of the temperature sensor is the smallest.
First adopt the conventional processing method, take out the filter on the lower left of the machine, and find that the filter has a serious accumulation of dust. After booting and using, it is found that the system still displays an alarm prompt, and the system will automatically shut down when the time is up.
Walking to the back of the machine, the temperature is obviously increased, and the back cover of the machine feels hot. After turning off the machine, open the back cover of the machine, observe the internal panel, and find that there is very little dust accumulation. After turning on the machine again, check the cooling fan at the rear of the device. All five fans are rotating. Enter the temperature and voltage utility interface, and see that the return values of other temperature sensors are all 30 ~ 55 degree, but the temperature of the right graphics card is 94 degree. The reason for the failure is that the graphics card fan is aging, the necessary speed is not reached, and the insufficient heat dissipation capacity leads to high temperature Alarm, the device runs normally after replacing the fan.

Summary
The maintenance of ultrasonic equipment must first learn to analyze the error report information, analyze and locate the fault according to the specific description of the information and the error code, and then troubleshoot the fault according to the order from easy to difficult, from outside to inside. The inspection room of the ultrasonic equipment is required to maintain a certain temperature, humidity and cleanliness, and the filter screen should be cleaned regularly. It should be noted that the cleaning period of the filter screen should be appropriately shortened in the dry season.

Philips IU22 ultrasound cannot be turned on

Replace the system hard disk first, and report 602 error after booting. It is analyzed that the codes of the software and sub-hard disks do not match. After the backup of HDD1 and HDD2 is replaced, the device boots normally, enters the system operation interface, and tests all functions are normal.
 
Summary
When conditions permit, it is important to do a good job of backing up equipment systems and data. At the same time, the hard disk of the scrapped equipment can be used to back up the system and data of commonly used ultrasound equipment, which can effectively use resources. The hard disk capacity of early ultrasound equipment is mostly 500G, and hard disks above 4T may not be recognized. Backup should be performed with 1T or 500G hard disk.
Philips IU22 ultrasound device has no display

Fault phenomenon
After pressing the power button, the screen of the Philips IU22 ultrasound device does not display an image.
Fault analysis and Troubleshooting
The device's non-display failure is roughly divided into two categories: the display or the display cable is faulty; the computer host fails to start normally. After the device is turned on, you can feel the vibration of the host when it is running. Press the shutdown button to shut down normally and judge the host computer to be normal. The fault may be a fault in the monitor or the monitor power cord.
Remove the device monitor, connect a computer monitor with DVI interface, the image display is normal, and finally determine the monitor failure. Disassemble the monitor, detect that the high-voltage board of the monitor is burnt out, and the front-level power supply of the driver board burns through, and the equipment is used normally after maintenance.
Summary
The failure of the display can be easily detected by the replacement method. It should be noted that the resolution of the current computer display is relatively high, the hardware of the ultrasound device does not support it, and a compatibility error will be reported after booting. When replacing, you can connect the original monitor to boot, unplug the video cable and connect to the new monitor.

Troubleshooting of GE LOGIQ series ultrasound system
 

Fault phenomenon:
The fault will occur during the first start-up in the morning. The start-up of the machine is in a normal state, and the probe can be effectively switched, and then the fault will occur. At this time, the clipboard of the machine will become larger, and the run key and set key at the lower right of the display will flash.

In this case, the buttons and the touch screen have failed, and pressing the shutdown button will directly pop up the display frame of the system that is not responding. You cannot use the mouse or the touch screen to select. You can only use the left and right buttons to complete the selection. Among them, the restart cannot be chose, and then it will enter the white interface, and there is no response to the forced shutdown. The only measures that can be taken are to unplug the power, and after restarting, the machine returns to normal.

Analysis and Troubleshooting
Copy out the error log in time and enter the CSD for testing. The result shows that it passes. Afterwards, the corresponding inspection of the front and rear connection cables and the hardware of plugging and unplugging the front and rear ends is carried out, and the backup software and settings are also included, and the touch screen and the trackball are replaced.

Observation and research on the error log can find that many of the trackballs and touch screens have faults, and find the relevant logs according to the time when the fault occurs. However, there is no error record in the process of failure.

Through the verification of the fault time point, it can be found that there are many contents related to the information of Tr-ballBut and TouchPush. Then, combined with the flashing problem of the run key and set key at the lower right of the display when a fault occurs, the fault location can be found out. The machine will crash itself in the process of responding to the trackball and Touchpanel, but it is not used as an error in the error log, so the trackball and touch screen can be replaced to solve the machine's faults.

Using manual analysis of the OPPanel schematic diagram, we can understand that the touch screen and trackball have been connected to the USBHub of the Maincon-trol board in the operation panel, so we can understand that the main cause of the failure is damage.
Troubleshooting of GE Vivid 7 crashes


Fault phenomenon
GE VIVID7 color ultrasound equipment crashed twice within 2 weeks, but it was normal after restarting, and it completely crashed on Monday in the third week.
Error reported at startup: DolphUI (0x490): ACQ-SRC: RFT download ing failed!
After displaying the Windows XP interface, an error is reported and the sound window cannot be entered.

Troubleshooting 
First of all, it is suspected that the system files are lost. After reinstalling the system, the failure remains. Then replace the hard disk, install with a new hard disk, enter the fifth bar of the progress bar when restarting to the Windows 2000 interface, and die. Restarting the system installation can continue, but the system files cannot be installed completely. After the hard disk is replaced with the same device, the installation is completed automatically, and the device starts normally, eliminating the hard disk failure.

Now that ultrasound technology is relatively mature, most manufacturers design ultrasound equipment into a front-end probe receiving and transmitting part and a back-end image processing part. RFT is the communication board between the front-end and back-end. According to the fault prompt, it is presumed to be a front-end and back-end communication failure of the device. If the RFT communication board is replaced with the same device, the fault remains unchanged, so it is determined to be a back-end PC motherboard failure.

After replacing the RFT board of the original device, the error report changes as follows:
DolphShell.exe has generated errors and will be closed bywindows. You will need to restart the program. An error log is being created.

After replacing the VGA (Video Capture Card, hard disk module), the failure remains unchanged, and after replacing the power supply, the failure remains unchanged, so the main board failure is judged.

Because the front-end and back-end communications are serial links, start with serial communications. The back-end computer has the same serial port structure as the desktop computer for office use. When the serial port of the computer is normal, its 17 feet should be level-free. If you remove the three insurances of the parallel port and there is no level, you should suspect it is a serial management chip The problem. After replacing the serial port management chip GD75232, the fault is resolved and the device returns to normal.

 
GE Vivid 7 Failure to boot Troubleshooting


Fault phenomenon
The GE Vivid7 color Doppler ultrasound diagnostic system is used as an example. After the device is turned on normally for about half an hour, the screen goes blank momentarily, and there is no response after turning on the device.

Fault analysis and Troubleshooting
The first step is to check the color Doppler ultrasound diagnostic instrument connected to the AC 220V power supply and the AC fuse. If there is no abnormality, eliminate the fault caused by the input part;

The second step is to open the case cover of the color Doppler ultrasound diagnostic instrument. It can be seen that the circuit boards in the case are arranged in a compact manner, and a large amount of dust is attached to the surface of the circuit board. After the dust removal treatment of the circuit board, the experimental boot test shows that the color The Doppler ultrasound diagnostic instrument starts to return to normal, and all functions can be operated normally, but the color Doppler ultrasound diagnostic instrument shuts down again and the black screen cannot be turned on again after about 0.5h after startup, and the fault phenomenon is exactly the same as before;

In the third step, the observation shows that the CPU cooling fan of the color Doppler ultrasound diagnostic system cannot run normally. After the shutdown, the cooling fan is directly replaced, and the failure is finally eliminated, indicating that the failure is caused by the failure of the CPU cooling fan.

Summary 
In the practical application of color Doppler ultrasound diagnostic equipment, there are many reasons that cause the CPU to overheat. In addition to damage to the cooling fan, it may also be caused by factors such as too compact device design and accumulation of dust on the surface of the circuit board.

In addition to the need to replace the damaged cooling fan in time to help the color Doppler ultrasound system to reduce the temperature during operation, the maintenance personnel should also carry out dedusting and maintenance on the equipment regularly to ensure the safe and reliable operation of the system.

Philips EPIQ 7 system reports error "511"

Failure phenomenon
The Philips EPIQ 7 Ultrasound was suddenly powered off during use, and then suddenly powered off after it was powered on. After encountering two sudden power failures, it turned on again. An abnormal startup failure occurred. The display stayed on the "PHILIPS" interface for a long time, and finally entered the boot interface. Error "511" is reported, and the device cannot be used normally.

Failure analysis and Trouble shooting
According to the description of the operator, re-plug the main power cord of the EPIQ7 ultrasound and press the power button to turn it on. It is found that the interface that the display stays on for a long time is the BIOS detection interface (see the figure below). Restart into the BIOS interface and check that the BIOS settings do not appear The problem, according to the BIOS test, is only for the self-test of the front end of the EPIQ7 when it is turned on. Therefore, if there is a problem with the front end of the device, it is suspected that the fault should occur outside the front end.

Unplug the ACQ and power REG PCB from the back-end PC, remove all the front-end load, and leave only the PC part. It is found that the fault remains, and it is determined that the fault should lie in the PC part.

Enter the boot interface and report the error "511", check the error log and find the message "Plantform Monitor failed to start the Digital Media Manger process", which means that some components have failed to start, so it is necessary to find the failed components to determine whether it is the root cause of the failure.

Remove all the circuit boards and cables connected to the PC motherboard, leaving only the hard disk, memory and graphics card. After restarting the EPIQ7 ultrasound, it was found that the BIOS detection interface was quickly completed, and the system was turned on normally without an error, and the fault was eliminated.

It is judged that the damaged parts are among the parts that were just removed. Insert the parts that were just removed one by one each time and then restart the device. It was found that the fault recurred after the DVD cable was plugged into the motherboard. The fault still exists after replacing the DVD cable. The DVD damage caused the EPIQ7 failure. After replacing the DVD, the EPIQ7 is normal, and it can be used again.

Philips HD15 Ultrasound System Troubleshooting 

Faults phenomenon
The HD15 ultrasound cannot be turned on. After pressing the power button, HD15 cannot start normally. Check the equipment failure, and find that the host starts and then stops when starting up, and the display is blank.

Troubleshooting
First check the power supply, the wall socket voltage is normal, and the voltage entering the main power supply of the device is also normal. Make sure that the fault lies in the HD15 device itself.

The power supply principle of HD15 is that AC current passes through the main power supply of the equipment and then enters the ATX power supply at the back end. After the ATX power supply receives the power-on signal, it passes the electricity to the PC motherboard, and the PC motherboard passes the electricity to the back-end ACB circuit through the front and rear interface boards and cables. Then the ACB circuit board will transmit the trigger signal back to the main power supply. After the main power supply receives the trigger signal, the display and the front end are finally activated, and the entire device can operate normally.

According to the power supply principle of HD15, the ATX power supply at the back end starts normally after booting, but it stops and the display is black. It is judged that the device has not been fully started. At this time, the problems of ATX power supply and trigger signal switch can be ruled out. Consider the following problems. aspect:
① The interface board and connection of the back-end PC are faulty;
② There is a problem with the front-end circuit board, and the trigger signal cannot be transmitted to the main power supply;
③ The main power supply and accessories are problematic, and the trigger signal cannot trigger the main power supply.

Check that the interface board and wiring are normal, no looseness or damage; connect the NPOWER ON pin on the front circuit board to the metal casing of the device, force the power supply to operate, and the fault still exists.

After troubleshooting the first two problems, it was determined that the fault should lie in the main power supply and accessories. Therefore, the main power supply of the HD15 device was disassembled, and the appearance of the components on the power board was carefully checked. At this time, a slight bulging phenomenon was found in a capacitor It is suspected that the capacitor is the cause of the failure. After removing the capacitor and measuring with a multimeter, it is found that the capacitor is abnormally charged and discharged. After replacing the capacitor with the same specification and re-welding, the test main power supply is normal, and the equipment failure is repaired.
Philips IU22 cannot start after ultrasonic power off
 

Fault phenomenon
Philips IU22 Ultrasound crashes during use and cannot be started after a power outage.

The operation staff of the department reported that the system crashed during use of IU22 at first, and the system crashed after being shut down and waited for 20 minutes. After a period of use, the system crashed again. The cycle repeats. After a sudden power failure occurs when the system crashes The device cannot be started.

Troubleshooting
The IU22 ultrasound cannot be started. First consider whether the power supply is normal, so first check that the input voltage 220 V, AC, and the stabilized power supply line are normal, and eliminate the abnormal power supply.

Because the IU22 ultrasound encounters a short power failure during the crash, it is suspected that the power failure may cause the IU22 to enter the over-voltage protection state, so the capacitor voltage is released after the power failure, and then the power is turned on again for testing. The IU22 resumes and starts but stays The “Loading” interface cannot enter the system. Contact the manufacturer’s engineer to suspect that the system file is lost due to the power failure. It is recommended to reinstall the system, find the local system CD and reinstall the system, and the IU22 will start normally.
Considering that the operator has reported repeated crashes, based on previous maintenance experience and the description of the operator, it is suspected that the IU22 ultrasound has poor heat dissipation, causing the phenomenon to reciprocate. Therefore, the casing is removed and it is found that dust has indeed accumulated in the casing. Then, clean the fan, remove the dust, clean the filter, and dry the filter. After installation, the IU22 starts normally, and observes the later use process. No system crashes during use. So far, the fault is repaired.
