Is there a board I can remove and take somewhere for service? I paid a repairman to come out and troubleshoot it, and he did, but they want an additional $475 to remove and replace these two little electrical items. I realize one might have to remove old solder, or solder something in place, but if I had a schematic on it....I would try it myself. Can you help me Charles

I just read that you no longer have a schematic, my bad. |
That price doesn't sound that unreasonable to me considering the work required to fix a TV like that. Those two parts are just the obvious problems. There's a very good chance that he will run into a problem that can't be repaired after spening a lot of time on it. There's a good chance that it needs a part that is no longer available. The high estimate is to make it worth his time and to discourage you from having it repaired. Even after a repair, these sets often quickly develop other problems. They are very unfriendly to work on (lots of connectors and cables that have to be removed to get to the boards, then plugged back in before you can test it). Every Mitsubishi I see seems to have dozens of leaking capacitors that must be replaced.
