Appears to be a switching power supply, with a regulator board mounted above it. It seems the switching?power?supply is not starting up. Not even the fan runs.

Hi Rik,? I guess the problem will be on the rear most power supply board. Not sure what it is. Rick

My 8935 was working fine. Passes all tests. It was powered up on my bench and suddenly shut down. It will not power up. The GFI is not tripped. If I turn on the power switch the unlock led blinks and there is a click in the speaker, this repeats over and over.

I am guessing there is a power supply problem.

Any suggestions here before I dig into it?

Thanks
