820-02100 power issues

[Kyle93]

This has no liquid damage, looks pristine, and randomly died on the client. Magsafe 3 and usb-c turn on for a few seconds and then goes back off and back on. All voltages appear during these few seconds including PP1V8_S1_CLVR_VDDH.

Does this sound repairable and is there a boardview available yet?

This board is having the exact same symptoms as this post https://boards.rossmanngroup.com/threads/820-02100-charging-pulsing.63686/

Boadview available in pdf format only.

Did you test the board alone on the desk?

 

[Kyle93]

Yes

Same behavior in the case or alone on the desk. CPU warms up if board sits on desk long enough with magsafe or usb-c continuously blinking every few seconds.

Anymore ideas on this one or should it be blamed on bad M1/ssd issue?

No way to put in DFU mode?
