UN55h6203afxza I have replaced both main board and power supply with new original Samsung parts yet no light and no sound, nothing. Any suggestions. Thanks
@ogundu make sure that you have a good power outlet and that your power cables is good. Next check on the power board fuses with a multimeter to see if you have power going to your board. If so, then you may have an issue with your button bar. Post some good picture of your boards and the wiring so we can see what you see.,use this guide Adding images to an existing question
