Thanks Jeff!

I give it a try and let you know how it went.

Jeff,

I re-did the B to B, B+ black wire and it had no effect.

Thanks for the 3777. I habe been able, using a volmeter, see that AC poer comes in, goes through to T801, and comes out the other side. I have no DC voltages at all sucha s 5.0V, 12.2V or 9.0V appearing anywhere. So the ICs aren't powered and can't send the signal to open the relay to power up the rest of the system.

Any thoughts on what is happening here?

Mike

This set uses a standby power supply design....see if you proper voltages on all the pins of Q840 (L78MR05)

That L78MR05 is a common failure part. That is a combo 5v standby regulator plus reset circuit. The reset circuit seemed to go bad in those a lot.
