Is my TV screwed

[dyslexic]

I have the Samsung au9007 50 inch 2021 and the screen looks like this I've cut off all power to it for like 30 odd minutes I've factory reset it hoping it was a software issue nothing 

I've just put a white back ground on to show it more easily

I would say the best thing to do is contact samsung support and get an idea from them. To me this seems like it may need a repair

Looks to me like the backlight may have failed.

Need to contact an authorised Samsung Repair Centre I think.

Definitely a repair job 😏. Good luck, I hope they will sort it out for you.
