[TV] Re: Sony KV35S65
Thank you, Al, for looking up the info in WinSTIPS for me. I think you have
given me the steer to the circuit that is giving the trouble. I have been
working all around that PIN circuit never thinking it could be the trouble.
Will keep you posted on results of my new search on that circuit. Thanks
again....Wayman
