So is the screen blanking out due to a bad flex cable? Has anyone been able to remove the lcd without cracking it? If so what is the secret? I've done 4 of these already and have never successfully been able to remove the adhesive without cracking the lcd. I've tried heat as well, it actually made it worse.

do you have a link? I can't find any that cheap
I got this screen to come back with the opening and closing dance again....turning promotion down to 47hz helped. it was working for around 5 hours today. then I switched it back to promotion and it went off again after 15 minutes 🤷Comment

can be liquid damage of TCON board/or motherboard. but you cannot remove LCD without damage. what left? use WD-40, sometimes it helps
ps. wd-40 can make stain on screen. be aware

Dear BADCAPS Forum,
I am happy to have found this place and would love to get some input on my issues with a MacBook Air M1 (A2337).
A couple of days ago, I was using the MacBook on a low battery, and while running VS Code it shut down due to low battery. I rarely let it reach the point where it turns itself off, and if it does, I usually charge it immediately. This time, however, I left it uncharged until the next evening, and when I plugged it in, nothing happened. I waited until the following day, and still nothing.
I followed all the recommended troubleshooting... -
I'm working on a MacBook Pro A2442, board 820-0298-A. This device was liquid damaged and had no power. After I repaired the liquid damage, I find the device powers on and works with external video, but backlight is not working.
Anyway, I really want to improve my fault tracing skills, instead of having to rely on others to always tell me where to look and what to check. In this case, I have a question about navigating schematics. If I wanted to trace the backlight power circuit, how do I find where that circuit begins? If I search for "lcd" in the schamtic, it is listed... -
Hi! I'm a bit new to this whole repair world. But this is what i'm working on:
A Macbook Pro A1990 (820-01814) from 2018. It has no image – or backlight for that matter.
No history of liquid spills or anything. It's fully functional on external monitor - and the webcam works.. But it doesn't seem like the internal display is even detected.
Sometimes the backlight lights up, when booting into recovery mode. (No image still)
That's the only progress I've gotten.
I tested the panel on another Macbook, and the display worked perfectly.... -
Hi all! MacBook Air A2337. There are no traces of liquid or obvious damage, the motherboard is visually in perfect condition. The image is displayed on the external screen, but only the backlight works on the internal screen. There is no image, and the camera on the built-in screen does not work. How to exclude during diagnostics that it is the screen that is broken and not the motherboard? What signals should be present on the connector with the screen removed and connected?02-07-2024, 08:07 AM -
Hey guys!!
I’ve got a question here!
I have a MacBook Pro A1706 that needs the backlight cable replacement — the well-known issue — but the problem is that the code on my original cable is 821-00571-A, and the one I have on hand to install is 821-01229-A.
Well, I asked ChatGPT about it, and the guy told me they’re not compatible and it could even burn the backlight circuit!!
Here’s what the bot told me:
I said to him: “I’m going to install the 821-01229-A.”
ChatGPT replied:Understood — but before you solder or install the 821-01229-A,...11-11-2025, 03:26 PM
