White / Pink light and lines on TV

[DanD95]

Hi, my TV has recently without warning started to show a bright white light on the top right of my screen and a pink set of lights at the top, ive tried removing Hdmi ports, checking alternative apps/channels, but nothing works, rebooting the tv after powering off for 30 mins does not seem to help either, the model is

UE70TU7100, im still within warranty, would this issue be covered?

Go in to setting and do a diagnostic test, screen test.

I ran this test but it doesnt help as the picture is a light background where the issue visible clearly, on every other channel, diagnostic page etc this issue is visible, just not when the background matches the light on the top right

I had this issue, turned out, that I needed a new screen
