Macbook Pro A1286 GPU issue - Fan spin 2 seconds
820-2915 MacBook - No screen / no boot / no chime just fans spins for about 2/3 seconds
I have already checked the following core voltages:
ppbus_g3h=12.5v
Dcin = 16v
pp3v42_g3h =3.4v
ppvrtc_g3h= 3.3v
PP5V_S5=5v
PP5V_SUS=5v
PP5V_S3=0v
When I short power on pads , fans spin then shuts down and pp5v_s3=5v for about 2 seconds then shutdown to 0v.
I removed L2406 so I could program the g-mux but the same thing was happening - on , fan spin , off
ppvcore_gpu diode = 0v
ppvcore_gpu = 4.5 ohms
Any tips would be... -

Re: Will not turn on after attempting to change backlight fuse
I have a Mac Book Pro Mid 2015 A1398 , I have the audio jack stuck in optical mode , I replaced the jack and now the stuck in optical mode is gone. The Mac Book used to chime when powered on , but now does not.
But the sound still does not work from internal speaker or jack , if I connected Bluetooth headphones the sound works , if I plug a USB-Audio adapter the sound works.
I have checked the following :
Ok was checking voltages at C6600/C6601 = 3.3v and pin 10 audio jack...Leave a comment:
