Can I fix it or just buy another? Why is it not coming on.
chances are real good the led lamps caught caught in a power surge. i would not even attempt a repair, as this would be to costly. even you replaced the power suppy and get a standby light on, your led lamps in the screen have also failed. you may see these replaced on you tube. this is a very time consuming project. under warranty we would receive a new panel (screen) and remove the boards from current tv, and into the new panel (screen). thanks for asking, matt of martins tv repair.
