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

My Tv is turning off by itself


if all you want to do is disable the vcr portion turn the set on , install a blank vhs tape it has to be blank or the vcr will try to read it .and the tv and dvd should work fine. this is a timing problem in the vcr deck its not hard to fix but it is a pain.
