My screen suddenly died. Looks like typical damage, but with no cause.

The TV in question is a Philips 58PUS7505/12.

The problem appeared suddenly whilst watching TV. Remote still works, as i was able to pause what i was watching etc. The sound also worked for a bit, though heavily distorted.

The screen also constantly flickers, what i mean by this is that sometimes there is only a thin vertical strip, sometimes it takes over almost the whole screen (like on the picture attached)

Anyone who encountered a similar problem, any help is appreciated. I bought the TV only 2 years ago, and have not used it heavily, so i dont really want to buy a new one again. Thanks in advance
