@Petrymed: Please can you confirm the model number of your TV? In the meantime please can you confirm if this issue present on all sources? If you remove all external connections from the TV, and hit the menu button, can you still see the shadow/dark area? If you go to Settings > Support > Self Diagnosis > Picture Test, do you get any 'Fail' messages?

I kid you not, Samsung this must be a weird joke. Mine just died just about the same time!

Is this after your updates?

If the issue occurs during the Picture Test, it would be best if you contact a Service Centre, so an engineer can inspect your TV. This link will direct you to the closest in your area.

The issue is all the time ,not in the picture test , for example now all cables are not plugged in and is the same, I didn't use the TV for about 12h hours but the problem is still there

Oh, that's weird. Just noticed you're in Romania too, @Petrymed. I'd recommend contacting Samsung in your region and seeing if they can get an engineer to inspect your TV. This link will provide you with more details.
