    Screen Ribbon Bond failures

    I've been in the electronic world for 30 years and you never stop learning.

    I've mostly been in the repair end repairing failure do to component failure.

    I love the challenge of trying to figure out what went wrong.

    Working on CRT TVs was cool but I never liked the 19,000 volt on the CRT.

    Back in 1980 I got a 25,000 volt burn on my hand after replacing a CRT screen with a rebuilt CRT.

    Down to the point, I've seen quite a few TVs with screen ribbon bond failure.

    So far I see the main fix is to put pressure on the screen contact with rubber.

    Dose anyone have another technique maybe heat?

    Dose anyone know how the ribbons are bonded to the screen originally at the factory?

      I wonder why they put circuitry in the tabs. It a short distance. They don't put circuity in Plasma bonds. If heat is the issue put a heatsink on it or redesign it.

          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...

          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...

          ipad pro 9.7" blew a SMD component while replacing the screen 🤦‍♂️
          by ipatch
          i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
