TV turned off itself


Can you still turn it on?
If so, does it stay on with sound?

If the sound is ok and the picture is blue (even when changing channels, inputs, etc.) the lamp may have gone out.

Can you see the TV menu when you press the menu button on the remote or TV?

TV turns itself off after a few seconds, no picture at all


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
