I'm having a problem that i'm sure will be quite easy to fix, i moved this TV a few miles and now every once in a while the projectors just seem to shut off the audio stays on,but the screen goes out..It doesn't happen all the time,,sometimes it will work for weeks, sometimes days, sometimes hours.
If i turn off the main power and let it sit for a while it comes right back up,and works fine till it decides to do it again,,i'm kinda leaning towards a bad heat sink, electrolytic circuit breaker,something along that line,,any help would be greatly welcomed.

Find and solder up the vertical ic. It's a common problem with older Mits rear pro jo's.

Thin, about 12 pins, screw thru it, on a heat sink Mitts start usually with a la, ie la7838, la7845.
