Hi, I have a 42 inch Samsung UE42F5000 LED TV. It has been absolutely fine up until earlier today, about half of the screen has become dark/dim. It was sat idle on a Youtube video and it was not because of a fault of my doing.
I've tried resetting, software update, turning it off and on, unplugging it, waiting a minute and plugging it back in. What has happened, why, and what do I need to do to fix it?
Yes, it is still there. Try heading to: Menu > Settings > Picture > Expert Settings > Reset Picture. If that doesn't help, you can do a Factory Reset of the TV: Menu > Support > Self Diagnosis > Reset.
