A2289 / No Display / Chime / Restarts

02-20-2023, 08:07 AM

Hi,

I am working on a MacBook Pro A2289.

The MacBook powers on 20v / AMPS go up but return to 0 shortly after the chime.

The screen stays black.

I can get HDMI output. I tried to boot using an external drive, but the problem persists.

If left, the MacBook will keep restarting.

I tried a different screen.

Any ideas where to start looking?

Recently got MacBook Pro A2289 with interesting behavior. Pristine condition, no water damage, no visual issues whatsoever. It has no image, no Caps Lock, no life except the fan is spinning. But it is able to connect to DFU mode and recognized by another MacBook. I tried to revive but the process ends when the MacBook usually should show an Apple logo with a progress bar and giving me error AMRestoreErrorDomain error 9. I don't have CPU Vcore.
Now I can't able to connect to DFU mode either.

On the USB meter I got 20V/0.9A power draw, and keep looping....

M1 A2337 Macbook - No Display, likely due to logic board

Hi all!
This is my first post and also one of my first "deep dives" into electronic repair. I'm used to doing basic tasks with computers, like SSD/CPU replacement, thermal past re-application, etc. So here's the story...
I have a MacBook Air M1 that I bought to repair (I know, I'm weird; though I'm a CompSci major and want to learn more , and it will not display anything on the internal display. I have verified that there's no backlight, as I booted the laptop and shined a flashlight on it and there's no display; it does completely boot up, and shows fine on an external...
