Panasonic TV no screen

Hi

I have a Panasonic tx-48cx350 LCD TV that has stopped working. When I switch it on the Red LED comes on and the screen flashes a white flash maybe a couple of inches from the bottom of the tv but no picture. However sound does work. The last few months there has been a small area on the top right of the tv that goes dull for a few moments intermittently.

On Powerup the LED flashes 4 times pauses then flashes 7 times, on the 4th flash of the second sequence that’s when the screen gives a white flash around the location of the TCON board.

Hope you can help.

Hi

Thanks for the reply

Disconnected the LVDS cable, TV does exactly the same thing.
