Replaced main board tv still not working.
Hello I replaced my main board on my TV that I got for free. It’s a un50mu6070fxza. I replaced the main by the actual part number and to the “T”. When I unplugged the main board from the power supply, the back lights turn on. But once I plug it back on it turns off and I get nothing. Could this be a bad power board?
