Ok when I received this Mac it had no chime and mouse connected did nothing
I looked over cpuvcore and restored it. There was work done and a few joints weren't soldered well. No I have a issue with the onboard audio and no image
I plug a mouse in and it now blinks. Im looking at the schematic and see u9000 gets power from r9094 and r9094 gets powered by q9607.
L9000 0v
R9094 0v on both 1-2
Q9607 on en I get .3 v is one of these internally shorted ?
R9676 :
pin 1 pp3v3= 3.3
pin 2 gmux_s3_pd_en =.3v
C9010 0v on both pins
All_sys_pwrgd 3.3v
I thought since the onboard speaker wasn't working it might be the 3.3 power rail
Might have a issue but everywhere I search for this rail it's good. Please if my diagnoses is off please let me know. thank you everyone
