Macbook Pro 820-00239 short PPVCC_S0_CPU

[Tarek]

Hi,
i have a short on PPVCC_S0_CPU (no damage liquid).
where i can inject volt on which capacitor or coil ?
what maximum voltage ?

Thanks.

First of all, welcome to the forum!

What is the exact ohm value?
Compare with good board.
CPU coils have very low values as normal; depending by CPU type, of course.

I don't have a good board for check.
I have un short on C10G0 (continuity mode)
I remove C10G0 for check , but I have a short
I need to inject volt ?

"What is the exact ohm value?"
I hope you can find time to answer...

Sorry for the late, diode mode probe red on ground

L7210 (mode diode) 0.011 , value ohm 16.9 ohm
L7220 (mode diode) 0.011 , value ohm 17 ohm
L7270 (mode diode) 0.017 , value ohm 23.4 ohm
L8050 (mode diode) 0.043 , value ohm 60.2 ohm

thanks

Do NOT make wrong assumprions so easy.
I don't see any short.

L7410-30 are not connected to CPU???

 

[Tarek]

No they are not connected

I have a short on C10G0 mode continuity

My error, I was looking at wrong schematic; no L7310-30 on this board.

But now I cannot find C10G0...

I don't know why I got confused, thinking is 00045 thread.

So, L7410-30 exist on your 00239 board; there is iGPU power rail.
But you don't want to post ohm resistance to groud.

About C10G0, you've said to have 17 ohm at CPU core power rail; explained as being good value.
No idea why do you insist about a short there...
