Switch keeps freezing/horrible sounds/odd screen glitches. Even in Hekate

I can't even get a factory reset going, this has happened out of no where I've not played on the switch for a few days, I'd left it in the dock with the plug turned off. I went to use it today and unsurprisingly it was completely flat. So I switched the plug on the Dock and let it charge.

I went to use it and it wouldn't turn on. Turned it on and got a error code after a while 2168-0002.

I restarted the switch while doing a quick search on the computer and some stuff came up. Eventually the switch turned back on and I set about playing a game.

Not long after that the game crashed due to an unexpected error. Then a horrible high pitched noise happened and the screen fully spazed out. The switch then blue screened.

I turned it of and plonked it back in the Dock instantly and it booted up again! Not for long though.

So I decided to do a full NAND Restore. I managed to do it. But before I got very far into the GPP.

It did the same strange screen glitch again and froze.

The switch is back to original clean OS though. But it just won't seem to run. It charges. And it does turn on but it doesn't last long before it crashes again.

Sometimes I get the error code other times it completely freezes :/

Any help/ideas I'd rather not bin the switch not had it too long?

Cheers

 

Ofw? (Original firmware)?
Yes I can also get it to boot into hekate or reinx.
But it depends how long it is before it crashes and freezes. Sometimes I get couple minutes other times it shows switch icon and it freezes.

I've got rid of all the games on my sd card, and managed to do a full restore so any games stored on the internal storage are gone.

 

Yes. I tried booting with nothing in the slots.
Mmm gpu? It's all welds though. Gonna be fun to try fix my self.

 

Buzzing sound isn't every time though. I'll check.

How'd I do that? A good blow with some compressed air? Or take it apart and give it a good blowing

 

I plugged the headphones in and its not fixed. Thanks for your suggestion.
I plugged in my headphone. Music played but It still freezes after a while.

Thanks think it might be a new motherboard job. Or a just a new tablet.

... Or completely stuff it and never buy one. Hope emulator catches up.
