3 possible causes;
1 - the connections to the LCD panel are loose - open the tv and reseat them.
2 - the image processor's memory is defective and the image it generates is corrupted - the motherboard must be replaced. This should be it, check the codes before ordering it

3 - the LCD panel itself is defective - this is terminal, replacing the panel would cost more than a new tv,  time for a new tv.

Losing TV picture, screen goes blank,


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

My 42" flat screen phillips


I'd post TV model number first - it's on the back of the TV -and I'd also post a picture if I could.

The lines on the screen do not usually go with the "channel not available" problem and the likelyhood of you having both at the same time is , well, small.

Blinking light on 37" Dynex LCD


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
