Mitsubishi WS-65903 convergence problem

Can't Post

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 some broken solder joints on the two STK392-040 ICs. 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. 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.
Regards, Larry
