Good evening, I have an RCA D56W20B rear projection TV, intermittently it is shutting itself off. Just now I turned it on, came on for 10 seconds then turned off, this repeated 4 times, but now is functioning fine for over 10 min. Any ideas?

The small signal board is usually the cause of that symptom

RCA D52W20 TV powers on fine, then shuts itself off after 5 - 10 minutes. After 20-30 minutes, I can turn tv back on, but then shuts off again in 5 minutes.


it looks like the problem is in the 16v line..try to take it apart..and there's gonna be a 2200mf cap leaky.
that will solve your problem.

Thin red line, green line and yellow line going across the screen


the problem is vertical collapse,i am not so sure you can trouble shoot this on your own but you can send the board to eithor pts electronics or tristate module for repair
to get a price get the number off the sticker--left hand board(looking from the back) it will start CTC195---- write down entire number before you call them

Green Screen, No Sound, Shuts off after 10 seconds


Almost certainly the green picture tube is shorted. This is a very expensive repair; probably not worth doing.

TV turns itself off and then back on when I watch HD


If it played OK before you replaced the video board and now you have an intermittent problem Suspect the part that was replaced...Does this set have a video board? I can't find one on my parts list. Also there are a lot of ISSUES with aftermarket lamps not working properly on hi bright pictures. I can find out correct part #'s with complete model #.
