Hello,
I’m having a display problem with my MacBook A2159 (2019). The blacks suddenly shifted to a fluorescent blue, but the correct colors return when the screen is moved to a nearly-closed position.

I suspect a loose or damaged hinge-area connection, but I’m not an expert. I had it checked at Apple’s iCare and at third‑party repair shops, and they all recommend replacing the entire display — which is very expensive.

Does anyone know of an alternative fix or have experience with this issue? Any suggestions would be greatly appreciated.

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 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 everyone,

I'm troubleshooting a MacBook Pro 16" A2485 M1 Max (Late 2021, board 820-02382) with a completely dead internal display. No image, no backlight. External monitor works perfectly via USB-C or HDMI.

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...
