What you are describing is typical of when the firmware controlling the sets computer/mainboard goes corrupt, when that happens control of the electronics hardware is lost and the set will become erratic and eventually the set will flatline, this could have happened on its own accord or it could have been prompted by an input that the set did not like either way you have to call in the warranty for the set and a service agent will replace the main-board (firmware preloaded), I am sorry its nothing easier.

Let me know if you need more info

Do you still need help with this please?

Anthony. I bought main board like u stated and also powe board. Brought the items to aruba and had a local tech replace and. Television does not work. There is a smaller board next to the main board and tech believes this is what needs to replace. So I'm out of luck and problem was not solved.
Expert:  Anthony_Infotech replied 1 year ago.

Sorry I dis-agree where did you get the boards from please?

Customer: replied 1 year ago.
I purchased from lg and came in lg boxes, they would not cover warranty because out of country. Problem I have is I can not get parts on aruba so neded to bring parts here. The light on the power button just stays on green color. Nothing will come on screen. He used voltage testers and from small board next to the main board to the power board not enough voltage getting to power board.
