Just need to treat the panel like a baby, they are flimsy and fragile but fortunately it's 50 inches and not bigger, check some youtube videos on backlight replacement for procedure clues.

Your led tester not doing anything is a pretty good clue that it's probably bad led/s in backlights.

Samsung UN50KU6300F constant reboot, bad backlights?
This TV is in a constant reboot where the screen very dimly lights up for about 2 seconds and says SMART TV. I checked the power supply and visually all components look good. I unplugged the main board to see if the backlights would come on but they do not. I also tried my LED tester on the backlight plug and didn't get anything. I know some Samsungs will not light off a single led is out regardless of using a tester, so I'm thinking they are bad. I found a whole set for about $25 which isn't bad, but before I buy them is like to know if they would indeed cause a constant reboot like this tv is experiencing.
Attached is a short clip of it doing what it does.Tags: None
