The TV is a Mitsubishi 65" wide screen HDTV Projection set. Model
WS-65903. It's about 5 years old.

The original problem was a blue shadow about 4 inches to the right.
Seemed like a typical convergence problem as we'd done a couple of
very similar models recently. Never a call back.

Upon inspection of the Power Supply /Convergence board, there were the
typical broken solder joints on the two STK392-040 I.C. modules
which control the convergence correction. I ordered replacements put
them in and put the chassis back in the set. The picture looked
perfect

About a week later I got a call back. Same problem with the blue. Now
I don't see anything apparently wrong in the circuit, but I don't
just want to replace the modules, because I'm afraid they'll fail
again.

Looking for a schematic , service manual etc.

Also, if anyone has any suggestions or experience with this set I'd
appreciate any help.
