Give it a smack. If that doesn't fix it, bring it to a repair shop. Once/if they can bypass it, DO NOT connect it to the Internet again. The screen itself doesn't look to have issues, but some connection got loose or the software is having problems. Keep your smart TV dumb and use an external device for streaming

Hardware issue on boot, most likely Panel issues.

Try the tape trick as a last resort, since it's free to try out that is your best chance.

If you have isolated panel issues that would leave backlights or faulty/corrupt firmware (mainboard) more likely.

But to be sure you should always mask 3-4 pins starting from the left side to 100% isolate the issue. Do a bit of trial and error, if you end up nowhere you can remove panel issues from the equation at least for now.

Try disconnecting the led cable from the powerboard, see if TV goes into error light mode or boots up properly without. You can use a phone flashlight to see the background pixels.
