TV stopped to work and it is impossible to get it back to work (black screen) either from remote control or power switch located on the screen.
Standby LED steady red (no flashing )
I did all recommended tests from Samsung support with no positive result
I did open the oneconnect box to check the power supplies and all fine (12,8V dc and 349V dc)
Any recommendation/advice or return from experience will be appreciated
Thanks and have all a good day
