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.
