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.

Hi, It also could be the inverter board(s) that have gone bad. Check them out. If the inverter board goes it will also turn the TV off.
These boards are on the left and right sides of the TV pannel.
Good Luck with your repairs.

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

Are you certain the replacement power supply is good? A defective main board or power supply can cause this problem.
