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.

Regards

DJ

Hi

Thanks for the reply

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

Regards

@djbsystems the 4 blink code is known as power SOS. Try this. Disconnect the LVDS cable and turn your TV on. If it turns on then the issue is with the panel. If it does not then the issue is most commonly with the power board. Post some good pictures of your boards with your QUESTION so that we can see what you see. Aggiungere immagini ad una domanda

Hi @djbsystems ,

Saw on the images that you posted that it is a Vestel 17IPS20 power board.

This link may be of some help in finding the problem.
