820-00165 Liquid damage on u7200, r7202 blown

[2informaticos]

"r7200"
Not on schematic.
Check both R7201/02.

Check U7200 basic voltages; pins 1, 16, 17.
Do you get correct voltage on the other big coils?

sorry yes I meant R7202. Both sides are 8.59V on that.
on r7201 it's 0v on both sides
pin 1 is 0V
Pin 16 0v
pin 17 8.59v of course

also checked R1951 just in case. 0V both sides.

checked all big coils on top. everything is 0V except for L7560 and of course L7130 is 8.59V

I forgot to mention but you probably know anyway. Current state of the MacBook is green/orange light, no fan spin

I was thinking you get many more voltages, if went in search of CPU core.

Do you get 3V3_SUS?

 

[kevinklinkmuller]

0V on that. dead short on PPVCC_S0_CPU. 0 ohm short

yes I get 3v3_SUS

Guess it's dead

im so unlucky with these boards recently wtf

Lift CPU core coils and confirm if the short is on CPU side.
