Philips Android TV malfunction

Hello fellow redditors

So about 3 years ago I got a philips smart tv, the exact model is Philips 43PUS7406/12 43" UltraHD 4K HDR10+.

After those 3 years of regular 1hour usage per day it's starting to show horizontal bands that cover the whole screen, it also seems like its blinking around the middle.

I'll attach a video which will probably do a better job than my description.

My question is what do you think is causing this and if it is fixable, thank you in advance to everyone reading :)
