    Macbook Air 2020 13” model: A2337 backlight is on but no image

    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?

    Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
    by Ryan.man
    Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

    My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

    This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

    MacBook Air M1 A2337 Screen Replacement - keeping TrueTone
    by MagJ_
    Hello Everybody,

    I have a cracked screen and want to fix it. Usually, TrueTone will be gone as long as one does not prune open the screen and exchange only the LCD. However, I have seen the following Youtube video https://www.youtube.com/watch?v=MBNqhp6p_ZM, Solve MacBook M1 Pro screen true tone issue from the channel Master Liu, where only two chips called "display control chip" and "code chip" are swapped over to the new screen. I know, it is for the MacBookPro version. Though, I had the hope that it could work similarly for the MacBook Air as well.

    Hi there guys. This is my first post on this forum and my first attemp to fix a problematic board. Ill give you a litle pre history of the device. The Macbook was powering on but it wasnt charging (it was showing an X sign on the battery icon) i went to my local apple authorised repair centre and they told me that they tried with a new battery and charging port but the issue was still there so they said its a board issue. The laptop belongs to my partner and she already ordered a new one but she considers the data gone on this one. I want to try my best to fix it and surprise her. The laptop at...

    HP Elitebook Screen blank - backlights but no image
    by dicky96
    Hi guys
    I'm trying to fix this laptop screen

    Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

    OK so I have the original screen which works but has lines across the bottom quarter of the screen

    I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...

    Macbook Pro 16" A2141 screen artefacts, kernel panic
    by sofles
    Hi there.

    I have Macbook Pro 16" 2019, model number A2141, motherboard number 820-01700. I have some problem with dedicated graphic card. When Macbook switches to dedicated GPU it is getting instantly hot and starts to show glitches on screen, then it freezes (trackpad is not clicking anymore) and shuts down.
    I tried to reinstall MacOS But it was a pain, it started to show glitches in middle of installation and I could not finish it. I only was able to reinstall MacOS when I put Macbook outside (it is winter and -2 Celcius).

    Now situation looks like this, If...
