[SOLVED]802-00138 Liquid Damage

[RyanLEN]

Hi. I have a 2015 A1398 820-00138 with liquid damage & no power.

G3hot - .7
pp 3v42 - Good

G3hot Ohms to ground - starts at .7 to .4
CPU is warm
Liquid damage was around U7200

Any thoughts? Thanks in advance.

That seems like a short from PPBUS to CPU Vcore. If PPBUS is low voltage and CPU is getting warm then the CPU has already died.

Thank you.

Is there any other way to confirm that this board is a lost cause? Thanks in advance.

Resistance between PPBUS_G3H and CPU Vcore coil??

The CPU is heating up while PPBUS is low. Yeah this board is 95% dead.
