Question about Mitsubishi VS-5043/44 50" Rear Projection Television
I've been having problems with my tv for a while now and it just finally gave in. I tried to turn it on and the green power light came on for about 4 seconds and just shut off. There was no picture or sound either. Before this I was having trouble with the color alignment, the convergence I guess. The blue would not allow me to adjust up or down. But before that the picture itself would become distorted, wavy, and colors out of line. So I would stomp on the floor or hit the side of the tv lightly and it would fix itself. Any ideas as to what could be the problem? It is about 10 yrs. old but has been no problem until now. Thanks
You need to replace the two convergence ic's

You probably had a bad solder connection on one of the convergence modules, it's a common problem with projo tv's. that loose connection finally got bad enough to cause a short in the module, and that's what is sending the power supply into shutdown. have it fixed, and have them replace all of the convergence modules, not just the bad one. if one went out, the other(s) (there are 2, sometimes 3 of them) are the same age, and likely will also fail soon. ...... gee i was looking for a picture of one of those modules, but can't find one. well, anyway the modules are on large pieces of finned aluminum (heat sinks), and are about 3-4 inches wide, 2 inches tall, 1/2 inch thick, are usually black plastic, and have about 20 wire leads coming out of the bottom going down to the circuit board.
