No Power, No Stndby light, when the main brd is unplugged back light
Okay so I have a Samsung 55 in model number un55ES7100XZA . The television set was power cycling every couple of minutes now there is no standby and no power to the TV after replacing the power supply still no changes but when I remove the cable from the power supply to the mainboard my back lights come on. I don't want to continue to throw Parts at it because the main board is extremely hard to find is this a common issue for these TVs
