00165 MagSafe light fades away

[MaxFix]

Hi,

Water damaged board.
Turns on but MagSafe light fades away completely in 20 seconds.
Only corrosion that I found is on TP(1)PP3V42_G3H_BOOST. Testing point is completely gone.
PP3V42_G3H 3.42B
PP3V42_G3H 166 Ohms

Please advice how to proceed.
Thanks!

What happens with 3V42 and PPBUS_G3_H in this time.
Check the voltages.
Also test if board starts disconnecting LIO flex; no Magsafe light in this case, of course.

3v42 166 ohms= partial short

I was expecting some voltages...

 

[MaxFix]

PPBUS_G3H stays the same - 8.6V
Sorry how do I test if the board starts disconnecting LIO flex?

 

[2informaticos]

Measuring voltages on the big coils.
You can also use an USB mouse.

Looks like you can post.
But I don't understand this post.
Please open a thread with your problem...

Mouse keeps working.

So the board works without LIO flex connected?
In such case, bad LIO board, or flex.
You must inspect LIO connector on MLB too.

Connect internal LCD without LIO flex; check if get image.
In fact, you can mount the board in case and check it completely.
It will not charge the battery without LIO flex, nor sound available, but these are not the problems now.

1 pin corroded inside MLB connector. Replaced. Working.
