[TechAssist] Re: Sylvania TV/VCR model 3925LC

Winstips had several tips on the CCA252 pointing to a bad CRT.  I
disconnected the CRT.  No change.

There are a lot of places on the power pcb that are brown from heat. 
Forgot to mention that I tried jumpering the power relay.  Didn't help. 
Won't spend much more time on this piece of junk, but will give it one
more shot Monday.

Thanks for the suggestions.  Have a good weekend.  I'm ready to head for
the house!
