Makes no sense. Pin 2 on Q7700 is an output pin no ENABLE. But looking at R7701/02 then Q7700 is not turned on
Did you test with a good screen from 2015/16 nothing else works. If yes then first check SMC_LID then replace Q7700 and check if fuse is good of course.
Pin 17 on Q7700, that is interesting....U7700 I suppose.
Is there even an image? Check with flashlight on the back of the Apple logo
Because 1.99V is not right! Should be at least 3.2V. SMC_LID is the issue here.
So corrosion on HAL sensor or trackpad/connector.
How many "oops" wrong measurements have we had in this thread now? I dunno man, replace Q7700
duke you seems like a quick guy but If you didn't noticed it yet I am a newbie to the board repair and that is the reason I pay a subscription on this site actually to get better, but if you can't handle this il pay another one to help me with my oops..remember your oops as a newbie or close this forum.
