I'm woking on an A 1708 MacBook Pro (820-00875) Which has a bad trackpad but a functioning keyboard.
I replaced the trackpad with a known good trackpad and cable, reset SMC and PRAM, the trackpad is still not working .
The cursor does work with a USB mouse plugged in.
Checked the F4800...
Working on an A2159 (820-01598) that came in with physical damage to the LCD assembly near the hinge/screen bevel (see attached).
The board itself appears pristine with no signs of corrosion or liquid damage.
Tested with known good LCD assembly and the backlight is still out.
Measurements so...
Firstly I'd like to say that everyone at the Rossman Group does absolutely fantastic work. My hat's off to you.
I'm working on an A2159 board which is not booting or showing any signs of life.
Testing all the main power rails PPv20, PPv5, PP3v3, etc. I'm not getting more than 0.3V. anywhere...
