Thank Damon and Jim and any others that replied.
Replacing all three Optoisolator completed the repair. Part # 9338 941 50682
(CQY80N)
By the way Jim that CNW136 is an 8 pin IC. I can?t see how it would sub
for the CQY80N is a 6 pin IC

that number, like me.
But I'll guess that your Optoisolator is bad, which one you say? Try the BIG
ONE. I just replaced one and it's back in working condition.....which
chassis you say??? Well, it was a PTV 843.

have good SSB board and I put it in. This is my test board I keep for this
purpose. This board works fine in a 55P8241 that I have here. I have a board
ordered for the 55P8241. On back order of course. No ETA.
> 2. Replace D6003 and Resistor 3669 also when replacing D6003 replace
D6012 and D6025. What fun that was I've had dirt in my eyes bigger than
those surfs mounts. R3669 checked good.
