    Liquid crystal leak?

    Hi, I have never seen this before and I was wondering if anyone else knows whats happening here.

    The screen is not broken and the whole display is correct, but there are blotches of a black ink-like liquid in the screen. The ink can be pushed / moved slightly by wiping with a lot of pressure, but it stays in the same general area. I took the screen out to get the backlights for another monitor, and the ink is contained in the TFT glass.

    Usually when the screen is broken you cannot see the image below and to the right of the fracture because the bussline to those transistor has been severed, but the entire screen displays a good image - except for the ink blotches. I think the liquid crystal has some how leaked out of the glass and is under the polarizer.

    I was thinking if I could move all the ink into the side then the screen could be saved, but the stuff doesnt really move; it just kinda changes shapes.
    I should have taken pictures before the CCFLs were removed, but this is what i got.

    I think that's the liquid crystal. The mid layer of the TFT has failed and it's leaking into the top layer.

    It's scrap.

      M1 A2338 screen and touchbar issues after cleaning up liquid damage
      by jkruns
      Hello everyone,

      This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.

      My patient is an A2338 Macbook Pro M1 (late 2020).

      It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...

      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...
