I have a UN40ES6500FXZA that initially would not turn on, only flash the red led stand by light. I replaced the power board and it blinked less times. I replaced the main board and all the blinking stopped, but now the power board just clicks. I ordered another replacement power board, same thing, just clicks. All of the parts are allegedly from broken screen tvs. The TV only has 3 boards, i even replaced the t-conn due to finding one for $15, no change. So, all boards replaced and it doesnt turn on. I can pull the harness from the power board to the main board and the screen back light comes on. Any other suggestions?
