    Hi Brad,

    This sounds more like a Back Light failure than a Power Supply Module problem. Try running the TV in a dark room and get your eye close to the screen and then play a torch light across the screen and look very carefully for a very feint image, it will if there be very hard to see but visible, if you can see this the problem will be Back Light or Inverter failure which on this TV is not located on the power supply but on a separate Inverter Driver PCB, look for a smallish panel with a part number starting: T87 As all the LED Back Lights are run in series if one goes down you lose them all so bear in mind the the fault if you can see a feint picture could be PCB or LED based,

    regards,

    George

    Hi

    thank you did all that and I can see a dim picture, I’ll look for that smaller panel and go from there,

    Cheers Brad
