I have a UN50KU6300FXZA Version: DE07 manufactured in October 2016. Can’t get the TV on. Replaced the power board and the control board, worked for about 3 days, then the screen started blinking, the TV started turning on and off and after a little while…Nothing. Does anyone know if this is a recurring problem? What’s the deal with the various versions of this TV over just one year of its life? Would love a tech’s opinion. Thanks,
@wlmccoy this “the screen started blinking, the TV started turning on and off” sounds more like a backlight array issue. Make sure that the backlight is properly connected. You need to check the outputs on the connectors from your power board with a multimeter. Let us know what you find. It will also be useful if you post some images of your boards with your question so we can see what you see. Use this guide Adding images to an existing question for that
