no signal error

I am getting a self diagnostics check signal cable no signal error on a Siemens Acuson X150. I have checked the cables to the unit. The only one disconnected the staff report not using and plugging it in does not clear the error. I have rebooted the unit and still have the same error. Siemens is not providing tech support on this unit. Is there a service manual available? Does anyone know how to clear this error?

The issue you are having is with the BE board and RM board. These boards are the main computer of the system and are failing to start. You will want to repalce both parts.

For serial # less then 307998 use 10131804 and 10349420

For serial # greater then 307999 use 10349464 and 10349439

It could be power supply issue. Verify AC / DC Power Supply LEDs located on the back of the system. If DCDC power supply is bad then DC LEDs is solid amber (yellow orange) the system might have over current or over voltage or over temp. Same as the AC LEDs.

I am having the same mistake. ''self-diagnosis, check signal cable '' There is no problem for DC / DC power and AC / DC power. "Self-diagnostic control cable no signal" gives this error. Can your Help Please.
