I have this projection TV, 46", Chassis number AQEDP804
the problem is when you first turn it on, it has lines and vertical foldover at the top of the screen 1/3 down. no linerity problems.
as the set runs, it clears up.
I took out the mainboard, and that was a pain in the buttox to get to. had to tear it all the way apart, uses a 2 mirror system.
i ran an ESR check on all the capacitors in the vertical circuit, and around the circuit. found nothing seriously bad. found an 0.47 that was slightly out, but i ignored it because of it being such a low value.
then i checked every cap on the mainboard. found a bad leaky one in the powre supply, 470 at 50v, replaced that, resoldered the mainboard and vert sections. the resistors near the vert output transistors test ok. hooked it all up, the wavy sides of the pic are now gone, probably from changing the capacitor, but the vertical probem still exists. same with the convergence. the convergences is out of wack also when you turn it on first. but after it warms up, the convergence "snaps" back to normal, and the foldover slowly retracts back to the top, and it works like anormal TV.
dont understand, im not catching bad high ESR caps. any ideas?
