A lot of times this is traceable back to the power supply board in the TV. Open up the back and look for swollen or leaking capacitors on the board (distinguishable many times by the very large cooling piece and the largest capacitors.) Swollen caps can lead to very random problems, even protection shut downs to prevent further damage to the TV. You will only be able to get the parts from a smaller authorized LG retail store, and even then they will probably suggest to you to let them take a look at it to verify. Go in with either the TV or model and serial if you do decide to.
