7-13-3 No Boot
Check status of the ON/OFF button.
• If green, perform a hard shutdown by holding the button down until it becomes amber. If the system 
was not properly shut down it won’t boot up until the Back End Processor (BEP) is forced to shut 
down.
If amber, troubleshoot BEP Minimum configuration. Refer to 7-12-1 System Does Not Power On / Boot 
Up on page 7-50
* Basically you need to disconnect the PC2IP cable from the back of the BEP to isolate the 
Front End and see if that keeps the system from booting up. The Back End Processor will 
boot up in simulator mode, which would indicate that the problem is in the Front End. 
Check the LEDs on the FEPS. Check all the voltages out of the FEPS with a scope. If any 
of the LEDs is not green or the measured voltage is not within specs, replace FEPS.
* Also, try disconnecting the USB ports from the back of the BEP and reboot. Sometimes 
USB devices draw too much current from the BEP motherboard and will keep it from 
booting up. If the system boots up with no USB connections, perform a forced shutdown 
(you don’t have access to the OP Panel at this point) and reconnect everything to see if 
the system boots up normally. If it doesn’t, troubleshoot the USB devices such as the OP 
panel and Line printers.
* If the minimum configuration does not allow the computer to boot up, the problem must 
be in the BEP itself. Replace Back End Processor. This is a known problem with the BEP 
power supply. There is an FMI that will be coming out to address this. Until then the BEP 
is replaced.
• If not lit, troubleshoot AC distribution box. 
* Check AC power on the system inlet and verify that the circuit breaker is in the ON 
position.
* Check the FEPS fans. When the L9 unit is plugged into AC and the circuit breaker is ON, 
1) the FEPS fan is running, and 2) there is a +5V standby coming from the BEP that turns 
on the amber light of the ON/OFF LED on the top panel. If neither of these can be 
observed, replace the AC Distribution box. If the fan is running, but the +5V standby is 
absent, replace BEP.
* Check the AC output going to the modem, monitor and peripherals. They should be 
activated when the system is powered on.
* Check the AC power going into the BEP. If you don’t hear any clicking when trying to boot 
up, it is probably that the relays inside the AC distribution box are not being activated. 
Replace AC distribution box.

7-74 Section 7-13 - Troubleshooting TiPs
7-13-4 Image Artifacts
Image artifacts can be caused by any of the boards on the Front End. Artifacts are frequently due to the 
Front End Power supply or TD board failures. It is important to use the Diagnostic tools on the service 
interface to try to narrow down the failure to one or two boards. On Logiq 9 the “loop back” adapter is 
not necessary.
• Check FEPS voltages. You can visually check the LED status on the FEPS. If any of the leds are 
not lit, the power supply is defective. Run Diagnostics on the Power Supply to check the voltages 
and the tolerance. Check them with a scope as well look for possible high ripple. If this is the case, 
replace the FEPS.
• M12L Mux In Handle probe has shown some artifacts that look like a dark vertical line or lines that 
start at the bottom of the image. If this is the case, replace M12L probe. Refer to Service Note 
70303 for more details about this problem.
• Artifacts that look like white vertical lines, rain or snow cones in one or more areas of the image can 
be troubleshot in different ways:
- One troubleshooting technique is to swap TDs around to see if the artifact moves. (Pulling out 
the boards will keep the system from booting up; all the boards must be present for the system 
to operate)
- Another approach is to run the Visual Channel Utility to establish which channel the artifact 
affects. A channel is a signal path formed by XDIF, RF, Top Panel and TD board. Any of these 
boards in the path can be causing the failure. For instructions about troubleshooting 
Diagnostics, refer to 7-7-4-4 Board Level EBM Diagnostics on page 7-26.
- Be aware that the problem may only appear with one mode, probe or preset. Normally, in B-
Flow the problem becomes more evident and may be easier to troubleshoot.
- Check all the probes on all the ports. Remove all the probes, and then check each probe 
singly in every port.
* If port-related, replace Connector board.
* If the artifact only occurs with one probe, replace probe.
* If the problem persists with the new probe, reload software. Do not reload presets until 
you have tested the system with the default settings and be sure that the problem does 
not persist. User Defined Presets can carry corruption back to the system.

Chapter 7 Diagnostics/Troubleshooting 7-75
7-13-4Image Artifacts (cont’d)
- If you suspect that the problem may be caused by software corruption, please note:  Corrupt 
Presets can be identified by a problem in only one exam category using a specific probe, or 
a particular mode with a specific probe. Use the Clean Userdef function under Scanner 
Utilities, leaving the system with only the factory defaults. Be sure to back up the presets, 
including Connectivity configuration, TCP/IP page and Option strings before deleting the User 
defined files. Do NOT reload presets until you have tested the system.
* Before performing Clean User Defs function perform an Alt-D to capture the logs and 
preset files. If the problem is corrected with Clean User Defs send in the log to the OLC 
so that the corrupted preset files can be reviewed.
* After booting up the system, without starting any patient or accessing any menu, click on 
the Service Interface (Wrench Icon) and log in. Click on Utilities, then on Scanner utilities 
and then on “Clean User Defs”. Say OK and that will clean the folder. Shutdown the 
system immediately, using the System Shutdown function under Scanner Utilities. After 
rebooting, the system will come up with default settings. Only reload presets from disk if 
you are sure they were stored before the corruption occurred. If only Imaging Presets are 
affected you can restore the Connectivity presets by using the selective Restore function.
7-13-5 Connectivity
7-13-5-1 No Ping
• Check the speed of your connection. Follow Service Note 70302 to be sure Media Type is set for 
Auto Select. Remember that every time the system is re-ghosted, that setting goes back to the 
default value.
• Check cables. You need a cross over cable if you are connected directly to the device. Use a 
straight cable whenever you go through a hub. The use of a hub is highly recommended.
• Try connecting the network cable directly to the Ethernet port in the back of the BEP. If the 
connection works, troubleshoot the cabling to the external I/O.
• Check proper addressing. System should be under the same subnet or have a gateway address to 
be able to connect to another subnet.
• Check with your laptop if you can ping the Logiq 9 and the device (Printer or PACs).
7-13-5-2 No Verify
• Check if the device supports Verify. 
• Check port and AE title info. 
• Check if device is up and running. It may be up but in an error status. Reboot the device if possible. 
You also may need to reboot the LOGIQ™ 9.
• Use DICOM Doctor to evaluate errors in the communication.
• Clean User Defs before reloading software in case there is a corrupt Connectivity.res file.  Be sure 
to do an Alt-D to capture logs before performing a Clean User Defs so that if the presets prove 
corrupt the logs can be sent to OLC for Engineering to review.
• Reload software.

7-76 Section 7-13 - Troubleshooting TiPs
7-13-5-3 System Pings and Verifies but does NOT Send
• Check if device is up and running. It may be up but in an error status. Reboot the device if possible. 
You also may need to reboot the Logiq 9.
• Check device configuration.
• Clean the spooler (F4). If the jobs in the spooler cannot be deleted, you need to do it in Windows. 
These jobs may be corrupted or may be using a lot of space in the disk and cause problems sending 
Dicom images. Insert the Service Dongle, turn the system on and log in into maintenance and exit 
to Windows (the application should not be running). Then go to Windows Explorer and look for the 
file C:\musashi	arget\jobqueue.res. Delete the file.
• Check Connectivity configuration on the Logiq 9. 
- If it is a printer, check that the printer supports the film type and format. Some printers don’t 
support different image sizes (or different formats, such as the Patient entry screen). If this is 
the case, the spooler may show the job in a “Done” status but the images never get printed. 
Try sending secondary capture.
- If it is a storage device, check if the type of image selected is supported (color, gray, 
Multiframe)
- If it is a Worklist broker, you must use a Dataflow in which your Worklist is the primary input. 
Otherwise it won’t let you retrieve patients. Also check your Worklist search criteria 
configuration. Refer to User Manual (Chapter 16).
• Use DICOM Doctor to evaluate errors in the communication.
• Clean User Defs before reloading software in case there is a corrupt Connectivity.res file. Be sure 
to do an Alt-D to capture logs before performing a Clean User Defs so that if the presets prove 
corrupt the logs can be sent to OLC for Engineering to review.
• Reload software.
7-13-6 Back End Processor
7-13-6-1 How to differentiate BEP1 and BEP2.X easily
• If the MOD is 640M it should be BEP1. 
• If the MOD is 1.3G it should be BEP2.X.
7-13-6-2 System Halt Errors - Lock ups or Intermittent Problems
• Collect error Logs and send them to the OLC to be evaluated. Refer to 7-3-3 Collect a Trouble 
Image with Logs on page 7-3 It is extremely important to give as much detail as possible about the 
occurrence of the problem and the date and time it showed up. On the scan screen, press ALT-D. 
Reload software.

Chapter 7 Diagnostics/Troubleshooting 7-77
7-13-6-3 Drive Failures (CD or MOD)
• Check that the media (disk capacity and speed) is supported. 
- For the CD, there are 3 different speeds. Drives are listed like this: 24x10x40x. The first 
number (24x) indicates what speed the drive can write to a CD-R disc (write speed only). The 
second number (10x) indicates what speed the drive can write to a CD-W (write & re-writes 
many times). The last number (40x) indicates how fast the drive can read a CD. You only 
need to check the first number (typically 24 or 16) since we only use CD-R discs. The capacity 
is normally 700MB.
- For the MOD, the size is 3.5 inches, 230, 540 or 640 MB. The 230 MB disc is the most 
commonly used.
• Check Windows for driver issues. Go to Control Panel > Administrative tools> Computer 
management> Device Manager. 
• Re-install drivers if necessary.  
• If the CD drive is having problems, replace BEP.
• If MOD drive is having problems, try reloading software.
• If the problem persists, replace BEP.
7-13-6-4 Video Problems on the Main Monitor
• If the problem appears on the main monitor and it involves the whole screen, not only the image 
area, check your peripherals.
- If present on the peripherals, replace BEP.
- If not present on the peripherals, move the connector D4 (SVGA out to the top monitor) on the 
BEP rear panel to the C13. That connects the monitor directly to the SVGA port. If the problem 
is still present, replace Monitor. If not, replace BEP.
7-13-6-5 Simulator Mode
• Check the connection of the PC2IP cable on both the SCB board and BEP. 
• Check the part number on the SCB board. It should be 2260214-2 or 2260214-3. The revisions with 
earlier (lower) numbers had issues with the PCI connector. The connector on the board had 
intermittent contact on the 2260214 boards.  If the SCB has an older revision, order FMI 70168
• Check FEPS. You can visually check the LED status on the FEPS. If any of the voltages is missing, 
replace FEPS.
7-13-7 Operator Panel
7-13-7-1 No Audio
• Check volume settings in the application and also in Windows. 
• Use headphones, (the type that you use on a personal CD player or a laptop) to test the audio 
output directly from the back of the BEP. 
- If no Audio is present on the BEP, Reload software. If the problem persists, replace the BEP. 
- If Audio is present, follow the audio signal to the VCR or the OP Panel (the audio amplifier is 
located in the upper OP panel). The Audio output from the BEP goes to the Internal I/O and 
from there to the VCR and OP Assembly (use an adapter to plug the headphones to the RCA 
outputs of the Internal I/O). See Section 5-5 Operator Console Control PWA on page 5-31. 
If Audio outputs are working, replace Upper OP Assembly. Otherwise replace Internal I/O 
board.
- Always measure the speakers’ impedance; it should measure approximately 7 ohms. If 
Speakers are bad, it is possible that the amplifier on the Upper OP Assembly might be 
defective, too.

7-78 Section 7-13 - Troubleshooting TiPs
7-13-7-2 No Remote Control for Peripherals
• Check cable connections.
• Check configuration of the device.
• Clean User Defs before reloading software in case there is a corrupt Connectivity.res file. Be sure 
to do an Alt-D to capture logs before performing a Clean User Defs so that if the presets prove 
corrupt the logs can be sent to OLC for Engineering to review.
• Reload software.
• Replace the device.
7-13-7-3 No Video on LCD Display
• If the video is too dim, has dimmed areas or there is no video at all, replace the HV LCD inverter.
• If the HV LCD inverter is burnt, there is a possibility that the Digital Video Card on the PC also got 
damaged; in that case you also have to order the Back End Processor.
• Replace upper panel assembly.
7-13-7-4 Wrong Key Activated on the Touch Panel
• Perform Touch Screen Verification Utility, check first before calibrating. See section7-7-4-10 
Calibration Utilities on page 7-34. Access the Service interface (Click on the Wrench) and go to 
Diagnostics > Acquisition diagnostics > Diagnostics groups > Calibration Utilities > Start Touch 
Screen Verification.
• Calibrate touch panel. See section7-7-4-10 Calibration Utilities on page 7-34. Access the Service 
interface (Click on the Wrench) and go to Diagnostics > Acquisition diagnostics > Diagnostics 
groups > calibration utilities > Touch panel calibration
• Replace Upper Panel Assembly.
7-13-7-5 Touch Panel Not Responding
• Perform Touch Screen Verification Utility, check first before calibrating. See section7-7-4-10 
Calibration Utilities on page 7-34. Access the Service interface (Click on the Wrench) and go to 
Diagnostics > Acquisition Diagnostics > Diagnostics Groups > Calibration Utilities > Start Touch 
Screen Verification.
• Calibrate touch panel. See section7-7-4-10 Calibration Utilities on page 7-34. Access the Service 
interface (Click on the Wrench) and go to Diagnostics > Acquisition Diagnostics > Diagnostics 
Groups > Calibration utilities > Touch Panel Calibration.
• Reload software.
• Replace Upper Panel Assembly.
7-13-8 Probes
7-13-8-1 Probe Recognition
• Check all the probes on all the ports. Remove all the probes, and then check each probe singly in 
every port.
- If the problems persist with all the probes, replace the XDIF board.
- If only one probe fails to be recognized, clean User Defs to check if the problem is caused by 
corrupted presets. If the problem is not resolved, replace the probe.

7-13-9 I2C Buss
I2C is a clock and data bus. I2C control is embedded in the master chip i960 RP. The LOGIQ™ 9 
contains four separate I
2C buses. The first bus is located in the BEP:
- BEP PC2IP->PC/DGIO->IIO->EIO
-PC/DGVIC
- Patient I/O
One of the basic functions of this bus is carrying Start-up/Shut-down sequence for the LOGIQ™ 9. It 
also carries control signals for the PRINT keys. If the PRINT keys function fine to PRINT on a B/W 
printer or color printer but the Stand-by switch does not work to shut-down the system, I2C bus should 
be functioning normal but the ON/OFF switch itself (pinched cable or bad sticky button) could cause the 
problem.
The other three I
2C buses are located in the front end:
- EQ/EBM->RFAmp->XDIFF->Transducer (For E8C temp. sensing)
- EQ/EBM->TDs (Serial EEPROM for the VPD
Each TD board has an Analog Devices A/D converter with an I
2C interface on it for 
diagnostics. The converter reads transmit Vref (variable, 0-2V), the fixed A/D converter Vref, 
and has a built-in temperature sensor. Diagnostics reads back all of these over the I
2C bus; 
the I
2C master is on the EQ board.
- EQ/EBM->Back Plane->Power Supply (Fan speed and temperature control, +5, +3.3, +-6 V, 
+12, ProBias 120 V, Probe Rail +-100V)
These I
2C buses in the front-end card cage are for controlling the voltage on the TD boards, 
temperature control and FEPS fan control.
There is no classical type of sensor for temperature in the LOGIQ™ 9 Card Cage. There is an integrated 
circuit for the temperature sensing that is located on the Front End boards including TDs and EQ/EBM 
board.
A/D diagnostic goes through on the I
2C bus on the TDs. PCI bus is used for the communication between 
the EBM/EQ, SCB and BEP. Since there is no PCI bus on the TD, XDIFF, RF and Back Plane, I
2C bus 
goes through these boards from the EQ board.
NOTE: The ultrasound data for beamforming is transferred to the next TD boards through the Back 
Plane. I
2C buses never carry any ultrasound data!
