Flickering, at the top of the screen (only FireTV / AppleTV) otherwise not?

We have a problem with our Sharp TV, Sharp LC-80LE657E 3D

Not 3 years old.

Maybe you can help me already

For some time I have noticed that in the upper part of the TV, different times a minute, flickers. It's not easy to record that because it's only felt to be 0.3-0.5 seconds, but it's annoying…

We had a Fire TV and an old HDMI cable before.

I thought it would be the FIRE TV…

Fire TV with a brand new Apple TV changed> same problem

Brand new HDMI cable bought> same problem

All HDMI slots tried> Same problem

About SAT, I have not noticed or, yesterday in intense view, not synonymous.

If the AppleTV plays this screensaver videos, not even…

If I connect my notebook, either.

Thus, I think there's something with external / HDMI or similar. I'm Hagen? Or a setting?

For example, the series Dexter, and GZSZ on the Fire TV / Apple TV come i.d.R. 3-10 flickering per minute in the upper area.

I look forward to your help.

Here is a Dropbox link, with the documented flicker: https://www.dropbox.com/...P--ea?dl=0

At the video, the flicker seen at 0:30 and 0:35 and 0:42 and 0:50

Is the internet connection on the TV good? Maybe the television through its electronics disturbs the reception, but curious it is in any case.

That sounds like the only method that could now make mistakes because the rest works without Internet.
