    Macbook A2338 820-02020 No Image

    Hello,
    Namaste.

    I have a Macbook A2338 820-02020 with No Image and No Backlight.
    The device came in with a liquid spill at the Display Connector. The Macbook was on (tested with an external display).
    Cleaned the Board for any corrosion and Reballed UP7800.
    Post that we have backlight on the screen but still no Image.

    One weird thing is that even if we disconnect the Screen and connect it to an external video we still dont get the password screen - it shows a blank screen with wallpaper ( like it does when the screen is connected).

    The charging connector on the board JF600 is also burned out so only 1 charging port works.

    Any help ?

    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...

    HP Elitebook Screen blank - backlights but no image

    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 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.

    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...

    MacBook A1990 vertical stripes on external screen
    by ahoonid
    Hey everyone,

    I bought a MacBook A1990 with no screen. I bought it knowing the motherboard was defective but wasn't sure what the problem was until I received it. It actually turns on but as you see from the attachment, it has vertical stripes, on an external screen!!

    The board is neat. Not opened before for sure. Just a little dust, nothing more.

    Recovery using wifi can be opened, as can also be seen in the photo but it doesn't go all the way through after connecting it to a wifi. It downloads the initial Recovery files but never completes the rest of the...
