    MacBook Pro A1398 L2013 weird jumping screen.

    Hey everyone.

    I have a 820-3787-06 board from a MBP A1398 which has a screen issue. The problem starts with a bit of noise just like old TVs when booting and when the OS is on, screen jumps are added to the little noise on the screen. The jumps are millisecond and go back to the original place.

    Since there's a little crack in the corner of the screen, I thought it has to be the display. But to my surprise it wasn't since I tried it with a fully functioning screen.

    The same issue isn't happening with an external display. I did a gpu/cpu stress test on external display and everything went smooth.

    I then began to suspect the lvds connector. I replaced it and still no luck!

    Any ideas will be appreciated really.

      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 M2 A2681 Kernel panics after screen replacement
      by reformatt
      Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

      It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

      iphone XS turns off when press on screen.
      by smic717394
      Hi,

      I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

      Apple A1398 emc 2876 randomly black screen and fan rise
      by ktmmotocross
      Hello.
      Have this A1398 emc 2876 that randomly goes to black screen and raising fan. I know this was problem of gpu or gpu voltage controller, but this one is without gpu.

      Is there some known failure points on them or i just count on cold solder under cpu?

      Samsung UE55JU6800K half screen dark
      by Chrissygizmo
      Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
      I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...
