    Hanns G Hi221DPB Bottom 1/4 of screen issue(s)..

    This one started out as a "2 seconds then black" problem.. I was kinda hoping it was just a couple bulging caps but, no such luck.

    Ended up tearing it apart to the bulbs. One was burned out to the point of already being open.. I replaced it with a 19" bulb..(yes, 19" bulb in a 22" monitor.. extremely ghetto, I know :/ all I had lying around)

    Got it back together only to find 1/4 of the monitor now has horizontal+vertical lines.. that seem to be mostly non-moving..

    Have tried:
    Applying pressure all over the screen.
    Twisting the screen.
    Wiggling the ribbon connectors with it on.
    Pencil eraser trick to clean the ribbon connectors..
    Moving the lcd board with it on..
    Wiped the board with rubbing alcohol/air..

    To no affect.

    Any ideas?

    Would the driver board caps cause such issues?

    Let me know if you need more pics, there's really not much to see though, I've been staring at them for a couple days now.
    (the caps/boards that is)

    Thanks
    (sorry about the pic btw, camera sucks in low light..)

      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...

      A1502 screen only issues
      by aazjo
      I have a MBP A1502 (early 2015, 820-4924) with a screen that will not turn on. I have swapped screens with a cracked test screen and the computer boots and the cracked screen works for both backlight and image. The black/blank screen appears to do nothing.

      I have collected resistant data from the cracked screen connector pins and submitted to OBData server:

      1 PPVOUT_SO_LCDBKLT OL
      3 I2C_BKLT_SCL 9.97M
      4 I2C_BKLT_SDA 9.89M
      5 PP3V3_S0_EDP_R 79.10k
      6 SMBUS_SMC_0_S0_SCL 321k
      7 SMBUS_SMC_0_S0_SDA 323k
      8 EDP_BKLT_PWM ...

      Hitachi 58HK6100U - Horizontal Lines (Bottom third of the screen)
      by kdaniel
      As stated by the person I collected the TV from, it just stopped working overnight. However, I still gave it a go to try and repair it.

      There is a thread on the same TV but with slightly different issues where they had to tape connection points on the ribbon cable, so I want to see if this is repairable by any chance.

      After bringing it home and plugging it in, the TV turned on with its backlight working but had no picture. After removing the back cover, the first thing I tried is to unplug one of the ribbon cables and the situation is as follows.

      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...
