HP5890 Series II Gc. FAULT: DAC1 TEST

Hi there, we have an HP5890 Series II Gc.

After Power on the Testcycle shows "FAULT: DAC1 TEST" and not ready blinks. What is the Problem ?

The manual give  no possibel answer. Is there a solution ?


Thanks al lot Ish, but on the Gc is no signal kabel on P4 or P5 connected.

Disconnect from P7 is also negative.

Other ideas ?

Best regants.
