820-01041 wont boot

[Sr. Robot]

Hi, got an 820-01041 that wont boot. It will get stuck on apple logo or somethings just blank. It wont boot from external USB either. A few times ive managed to get it to connect to wifi only to get stuck there. DFU doesnt fix it.

The board looks in pristine condition.

May have a GPU problem.
Also gets stuck if try to start in diagnostic mode?

No response when using D or Option+D. Just stuck on logo

Check if goes into target disk mode.
If yes, test its SSD.

No target disk mode either

"DFU doesnt fix it."
Do you mean it completes DFU restore without error?

Restore works most of the time but revive device gives error.
