its time to call a service

Its Flyback lines caused by the G2 voltage being to high.check the voltage it should be around 520 volts

got the same TV with the same exact problem....what is it??? if u crack it tell me and i'll do the same...

its a LCD connectors. re-connect it properly. some loose connection.

Try to conect with DVD signal in A/V input if good picture, cable line are no good

Open up the TV and unplug and re-plug the connectors to the circuit boards. This is most often caused by a poor connection of the circuit board connectors.
