I recently purchased a Samsung 55” class NU6900 4k and have screen display issues with it.
Since I have installed it, there have been split second moments in which a two to three inch rectangular portion of the screen (the center or a little right of center) turns black and white from the top and bottom of the screen. This happened five or six times yesterday and several times over the last week since installation. Any ideas on the issue? Should I just return and exchange the device?
We are sorry to hear about this. Please send the full model and serial numbers from the television to this PM Link.
