    Apple A1398 emc 2876 randomly black screen and fan rise

    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?

          checked but found only that FDS chips faded out.

          for me this case looks like error from big tantal capacitors on old toshiba that badly filter voltage

              A2141 Screen replacement. Boots screen freezes on Apple Logo 1/3 status bar unless connected to second monitor.
              by abajor
              Having this very weird issue.
              The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.

              I swapped with a working screen from an A2141 waiting for parts.

              The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.

              The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...

              Hi guys, this my first post but i want to be brief about it, i recently got a MBP L2013, the problem was that after some use the macbook shutted down randomly, at first i suspected to be the battery, and after connecting it with the charger i noticed that i didn´t shut, but after an hour or so it shutdown, after that i started searching a solution to my problem, but my brother tried to help me to find the problem and it that process to replicate the problem he reproduced a 4k video in multiple tabs and not much time after the macbook shutdown to never power again, what i noticed was that the...

              MacBook Pro A1398 L2013 weird jumping screen.
              by ahoonid
              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...

              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...
