Mondo,
You're right, TP50F60, not sure where I got the extra "T" from. A curved
picture is one of the symptoms described by the customer so the STK's
are most likely the problem. Another member mentioned to look at
resistors in and around these STK's. Which ones are most likely to go
bad when these IC's become defective.

David, I hope you stay healthy.
I am just wondering if you typed in the correct model #.I am thinking
that its a
TP50F60 but I could be wrong. I think that set uses the STK-392-110 and
if
does,there is where your problem is.Replace them both and do some minor
convergence ajustments and all should be ok.This ic's when bad,will give
you a
distorded picture,including a curved pix and the red or blue way
out.hth.
