The screen is dark. it turns blue for a split second then goes dark. the sound is fine and i can change channels. i called westinghouse and they had no solution. i unplugged and nothing. should i start shopping? westingwouse said it could be a problem with the display panel, whatever that is. HELP!!
This sounds like bad inverter board.
Every time LCD goes from Standby to ON state - Inverter Board resets it’s self for approx. ~1 sec, during which time you should see blue screen.
Problem is that board detects problem with voltage/current on one of the seven transformers and shuts down automatically...
As to the costs:
- BestBuy repair service approx.. $600.00
- Buy new Inverter Board & repair LCD your self approx. $200.00
- Another option is to repair Inverter Board, but parts are sometimes hard to get...
Now for the DON"T TRY THIS AT HOME or AT YOUR OWN RISK solution:
-The cheapest method is to bypass protection circuit, by transferring good signal from working transformer (using 10nF/250V capacitor) to detection circuit at the faulty transformer.
Then watch movies on your LCD unlit BAD transformer totally BURNS-OUT.
This will be obvious by dark stripe about 1"-2" tall across your display.
Hopefully the only damage will be to the transformer and not CCFL (light behind your LCD), but when you are faced with a choice of using it for a while longer or throwing your LCD to garbage right now... to me this choice was simple.
Good LUCK.

I have the same thing. It worked yesterday but today, blank screen (blue at very beginning) then nothing. Sound OK. Even DVD player sound present but no picture.
Any thoughts?
What does "bypass protection circuit, by transferring good signal from working transformer (using 10nF/250V capacitor) to detection circuit at the faulty transformer" mean?
