I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

We have the RCA HD52w59 projection tv. The tv shuts itself off at different intervals. It takes approximately 1 minute to be able to turn the power button back on, however, I have to do that many times...


A problem in the deflection board. Could be a Cap. Resoldering the deflection board may take care of the problem. You need to call a TV man to do this kind of work.

Best of luck

TV shuts itself off. ON/OFF switch no longer works.


If your sure the switch is broken, you can remove the switch and directly attach the wires and plug and unplug to turn it off and on. But it sound like that if the switch is broken you have a slight connection and with an ajar it will turn off and on by itself. The good thing to do would be to purchase a push button switch at your local electronics store for between $1.25 to $10.00 depending on what one you would like to have.
if it is remote control you could have what they call a sliver on the circut board to that can cause this to make the tv turn off and on. Best way to check this is to take the remote batteries out and see if the tv still turns off and on. If so replace the switch.

DLP tv trouble shooting


Hi.
Yes it could be a cooling problem, If your tv has any filters remove & clean them ensure fan can turn freely & that nothing can or is snagging it.
