Image problem on Q80T

[charliepl8]

Hi. I have noticed that when I watch football on my Q80T the video sometimes slows down a little and also there are some artifacts like horizontal lines on players (please have a look at the video, player with white shirt). What might be a problem here?https://streamable.com/rza9as

If you only have the possibility then just return this ***** and buy something else.

Yes, this is what I will do. I have just noticed huge DSE on top of my screen.
