Re: Samsung UN65MU6500FXZA won't turn on

BruceTV, you have perfectly described the issue I am having with a UN65MU6500FXZA. I plug it in and the backlight and TV come on for a few seconds, then powers off. If I unplug the mainboard, it stays powered on and lit up. I read this post and saw that I do have 1 Blue and 3 Green lower driver boards. I tested with just the blue one disconnected, and it stays on. I also tried with the blue one connected, and the other side U cable removed, and it stays on. This leaves me wondering if I have the same issue or not. The blue board is marked...
