Good day everyone! I'm looking for some help/advice/direction with this Samsung UN65KU6300FXZA with no picture. When powered on the backlights come on for a couple of seconds then dim down for a couple of seconds then it powers off, powers back on and repeats the same process over and over again and there is never any logo or anything just a bluish screen and the only way to shut it off is to unplug it. when I disconnect the plug connecting the power supply to the main board the backlights come on and stay on, when I disconnect the ribbons on the main board one at a time it doesn't change the screen at all, I've always gotten a white half screen on the side that was disconnected with other tv's I've worked on. Is this a bad panel? I know there have been EEprom issues with these tv's!?!? Advice?
Here is the layout of the tv.
