Macbook A2141 PPBUS_G3H Shorted

[Instafixx]

Hello,
Macbook A2141 not getting on.

Found PPBUS_G3H shorted. Removed the Fuses F7000/1.

Diode Mode Readings (red to ground)
PPVBAT_G3H_CHGR_REG is.488
PPBUS_G3H is .013.

Started checking SSD Coils.
L9080 is 0.351
L9580 is 0.005

Bad news if NAND chips have been damaged.
We have many threads on the forum about SSD problems on A2141.

Remove U9580 and check again diode mode at PPBUS_G3H.
If short disappeared, check aat L9580 too.
If still low there, at least one NAND is fried.

Removed U9580. PPBUS_Short is Gone.
But L9580 is still low.

Then you have to deal with SSD failure now.

No Repairs Right?

 

[2informaticos]

Repair possible, but expensive.

 

[Instafixx]

Have another case.

Removed U9580.

PPBUS_Short .
Diode Mode Reading of L9580 was 0.003. After Removal of U9580 is 0.033.

C9580 is a blank point or is it missing on my board?

Also can this be repaired?

 

[2informaticos]

0.033 is still too low for NAND power rail.
At least one chip is bad...

Customer is willing to repair it at any cost - how can we proceed?

Search "A2141 SSD repair" on YouTube.
No idea what happened, but the forum doesn't accept to post an URL since 4-5 days...

What is actual SSD size of your machine?

I have a JC P13 Programmer. Can you guide me to the right Youtube Channel ?
