I am trying to fix my significant others Macbook Pro Early 2011, water was split on the keyboard and fun ensued!
The display doesn't turn on, checked with torch, doesn't work on external display. Otherwise it seems to be working ok, boots up, hitting the esc key gets the bonk noise, can shut it down using the keyboard shortcut from built in or USB keyboard.
Looks to be some water marks around U8900, checked PGOOD and this is 0V, so checked the following:
VIN 10.95V
PGOOD 0V
VID0 3.3V
VID1 3.3V
VID2 3.3V
VID3 0V
VID4 0V
VSUM 113mV
VO 0V
Measured without display or ext display connected. Can anyone confirm if VID3/4 should also be 3V3?
As this is coming from the GPU I assume if these should be 3V3 then it's the GPU that's hosed?
I'm going to replace the ISL6263 but thought I would ask whilst waiting for them to be delivered or if there is anything else I should check?
