Hi all.
We replaced a display assembly with an aftermarket screen.
The customer bought it back a few weeks later stating that the hinges are too tight.
I checked the system booted, and confirmed the faulty hinges, then shut it down, and removed the assembly and replaced with another aftermarket screen.
It failed to turn on, or display anything on either the internal or external monitor.
I then retried with the original screen but the result was the same.
I usually remove the battery cable and undo the battery screw to isolate the battery while disconnecting and connecting the screen, however, it is possible that I overlooked doing that this time.
Using a 96 watt Apple AC adapter.
20v on all 4 USBC ports, in both orientations.
No USB LED activity on a known good USB memory stick, in any port.
No capslock light.
No fan.
No chime.
PPBUS_G3H = 12.64v
PPVIN_G3H_P3V3G3HRTC =12.45v
PPVIN_G3H_P3V3G3H = 12.64v
3v3_G3H_RTC = 3.39v
PP3V3_G3H_RTC = 3.39v
PP5V_G3S = 5.17v
Should I try a DFU restore?
I'm a bit rusty on Macbooks lately.
Any help or suggestions greatly appreciated.
