I got a look at this set today, and isolated the problem to a surface =
mount
chip in the digital module. Hitting that chip with some freeze spray =
gets
things going again.

Now my problem is that I can't find that fiche in my files (88-001), the
only one missing over a ten year library of fiches. I can't find the =
chip id
on the board, but it is perhaps a 16 or so pin surface mount chip with a
heat sink on it's back (so I can't see a part number). Z420 diode is =
right
next to it.

The digital module has the following numbers on it: ASP002 and D1DSP.
Tritronic's part list doesn't include this module, so I'm at a loss =
right
now.

Thanks for any possible information out there.

This set arrived at the shop but I haven't seen it yet. It plays very =

well
for a while, then the picture becomes washed out and blue.

I searched around for a schematic (not in Force32), sams doesn't have =

this
model, but I did download a similar vintage sams.

This set is fairly old but the customer likes it. I suspect something on =

the
picture tube board, but would appreciate any prior experiences.

Thanks
