There is a high probability this is the tcon board, located at the back of the LCD controller.
I'll need the exact TV model number in order to be able to tell you what exactly the board number is.
It is not guaranteed - it may be the main board or, even worse, the LCD itself; not many people know, but the LCD dispay has quite some electronics literally inside it or glued to it in a totally unserviceable way.
If that electroncis burns out , the whole LCD goes to trash even if it's physically intact.
It's unfortunate, but not uncommon.
Still in your case replacing the tcon board is the first thing I'd try.
Ah, one more thing - sometims the cables that connect the tcon board to the LCD also burn and cause similar troubles. When replacing the tcon board that will become apparent.
Please rate this answer if it helps.

Look at the power supply first it may be going out; look for burnt parts, bad capacitors, etc. Look for 5vdc, 12vdc, and 24dvc.

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.
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

SOURCE: I just bought 32 inch
This is my second set in as much days from Best buy. Exact same problem.
I just bought 32 inch 2 hours ago, and am using it with an antenna. Almost every time I turn to channel 5, the remote freezes and I can't even use the buttons on the side of the tv.
