GE Logiq 7 PRO CW Problem

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi.

I have a GE Logiq 7 Pro where the CW function doesn´t work properly.
The PW function works perfectly, but CW only shows something if i vibrate the probe against the skin surface. If i place the probe normally against the skin surface no CW is obtained.
The diagnostic tests passed on all boards except STCW board.
The following testes failed:

STCW_CHANNEL_SV: FAIL

Delay Line/Crosspoint: FAIL

RF Gain Test: FAIL

What could be the problem?

Best regards

Paulo Ferreira

	Hi Paulo, I would guess that the STCW board is bad. I would check all power supplies, reseat the STCW board (Slot 2) and if available, re-load software before replacing the STCW board. Here is the part number: 2277244 STCW ASSY FOR GE LOGIQ 7 Please let me know if you need a quote. Best regards, Chris

	Hi Paulo, Yes. Please be sure to back up the image archive as well as all the customer presets at a minimum. Also, make sure you record the options string password and any DICOM/Peripheral settings. From there, most newer GE platforms have a Base OS (Operating System) CD which must be loaded first and then the Application Software CD which is loaded last. If you can tell me what version of software you have, I will see if I have a complete procedure for you. Best regards, Chris

	I changed the PCB STCW ASSy and the problem is the same, very low sensitivity in cw Doppler spectrum. Will reloading probe data resolve th problem?

	Hi Paulo, Have you tried a different probe? Have you checked all of your power supplies? Have you re-loaded both the base software and application software? Best regards, Chris

	Hello Paulo, The service manual does not list where the points are to check. Best regards, Chris
