1) Please upload good clear pictures of the whole backside of the TV showing all the board, and then good clear straight shot pictures of the whole power supply board (shopjimmy does not have pictures of your board for me to look at).
2) So what DC Voltages do you have on each pin of the PD connector (if it has connector named PD) when it is working and when it is not working? You need to report pin name and follow by the Voltage reading of each pin.
