I would suggest to measure all the voltages from the power supply to the main board.
Check the 24VDC line that powers up the inverter boards as well the other voltage sources.

Yesterday turned on all I get is a black screen,


Sounds like it may be the backlight inverter. Have you disconnected from the mains when you turned it off? leave it for 24 hrs then re-connect. this should be covered if you have a warranty

I'm having the same problem with the same TV. I called around to repair shops and I guess it's fixable. Haven't taken it in yet but I was told it most likely is a bad module. But this seems to be a really common problem with this television

Black screen


Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

I would keep hounding them for the warranty issue. Why do you have to spend a dime if the TV is still under warranty? I would just keep at it.


I hope I shed some light on the subject for you.
