Having the same mac where display is perfectly fine for 2-5 minutes after user login and then it starts flickering and after continuing this way for 30sec-1 min it goes dark.
capslock can be still toggled. Some kind of vertical lines appear(in different patterns each time) before going dark.
Is this a screen issue/flexgate issue or logic board issue? Dont have a spare screen to test.
Posted this here just to get confirmation whether its screen issue as customer dont want to pay for screen replacement.
Anyone knows?
PS
isplay fine on external monitor.

This is only a replacement of the LCD. Even replacing the T-con with cables did not change the situation.Having the same mac where display is perfectly fine for 2-5 minutes after user login and then it starts flickering and after continuing this way for 30sec-1 min it goes dark.

Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

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...

Hi All
I have MacBook A2442 which had keyboard replaced and now it doesn't turn on correctly, it have sound chime from time to time and Apple logo shows on the display and there is no backlight on, apple logo appear and stuck on kind of boot loop. But if one of the display flexes is disconnected from the motherboard then MacBook turns of fine with the external monitor and it keeps working fine.
Without keyboard its still have same issue, I don't have second display to replace it and compare but does display can make issues with boot?

Hi,
I have A2337 MacBook Air no sound issue.
I have replaced new Audio Board but still same issue. I went through repair wiki and checked critical voltages.
In terms of voltages, I have following voltages,
1 PP1V25_AWAKE_IO - 1.2V
2 PP1V25_AWAKE_IO - 1.8V
3 SPKRAMP_A_OUTP_R - 0V
4 SPKRAMP_A_OUTN_R - 0V
Am I missing any other critical voltages?
Thanks -
Hello. Sorry for the long post, but I am trying to decide if this is a simple battery replacement, or potentially something more complicated.
I bought an open box MacBook Air M1 2020 A2337. Seller claimed it was never used. Visually, it appears pristine.
On arrival, the battery was completely flat. Computer powers up and boots fine. Battery status showing 1% and charging, 1 cycle. coconutBattery showing 0 mAh and ~6 watts.
After some hours, the battery status did not improve. Restore via DFU did not help.
I connected the power adapter to a Kill-a-Watt...
