820-3662's Random restarting

[ALB-Repairs]

Hi, ive seen a couple of 15" 2013 retinas just randomly restarting. these are machines with no liquid damage, and i really havent had the time to try any repairs. But it doesn't seem related to any component being stressed.
We tried ram tests, CPU stress and GPU stress and it will run fine, but no matter what the system load is, it behaves exactly the same!
Anyone seen it and have any ideas?Thanks

Yup common issue and nope I have no idea what it is, hopeless cases for now.

is there anything you've tried so far? Ive seen PCH's cause this sort of fault on certain older model machines.
Thanks

I tried all I could. It is something with CPU power supply. As I said hopeless for now....
