    MacBook Pro A1909 LCD (no backlight)

    Hello Everyone,
    I'm looking at purchasing a used LCD from ebay for my macbook A1990 2018 15inch which LCD I cracked. Since new / used but working displays cost around 500$ , I found a Grade A+ LCD display for A1990 which has a good price of 110$ but has no backlight.
    I would need just to make sure that what I know/my reasoning is correct:

    - No backlight means flexgate issue, therefore changingthe flexcable would be enough (I can microsolder to fix the flexgate problem, done it a few times already)
    - Seller confirmed its a LCD issue, and not an issue with the macbook's motherboard backlight circuit
    - Question -> What other issues regarding the LCD could result in no backlight other than the flexgate issue?
    - Question -> Can the LCD logic board (the one which connects the LCD flex cable to the computer motherboard's connector) be swapped between LCDs?

    Thankyou!

      A1990 does not have flexgate issue. Liquid spill on display connector LCD or logic board side also burnt backlight connector . Dented bottom corners on screen can sometimes cause no backlight . Dustgate can cause no backlight.

          MacBook Pro 15" 2016 820-00281 no backlight. Another flexgate issue?
          by slimmy182
          Hello, I bought this machine from a friend. It's a 15 inch MacBook Pro 2016 model, logic board 820-00281. He said that the screen would go off if open more than a certaing angle but it's perfect working whit an external display.

          The backlight screen remains stay off even if I open just a little the lid, so I never see backlight work, but I can confirm that LCD show images as using a torch I can see it on the screen. It seems also that camera is not rocognized as the keyboard backlight stay off and touchbar have full brightness.

          Is this a classic flexgate issue? I...

          MACBOOK PRO 820-02100 BACKLIGHT ISSUE
          by AmirDZ01
          I have a MacBook Pro A2485 (820-02100) with a backlight activation issue. I checked the PPVOUT_LUXE output and I have 12V. I don't have any short circuit in the LUXE IC. Trying to restore the Mac in DFU mode to try to reconfigure the device gives me error 4042.
          Finally, I checked the UR330 and I have the 1V8_AON and LID_OPEN power supplies.

          I've given this a lot of thought. Does anyone know who can help?​...

          MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
          by rounin
          Hi everyone,

          I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

          🛠 Original Issue
          The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
          Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

          I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

          ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

          A1466 MacBook Air 13" 2017 Backlight issue works but then turns off
          by Stephen
          Hello, got a weird MacBook Air here
          board looks fresh and no water damage, backlight works and turns on and stays on when installing OS etc. However, when the os is installed and when the system files are loaded before the login page the backlight goes out. I have wiped it, NVRAM reset, etc and even took some other instances and this blows my mind, never seen this before. Backlight just turns off once the OS is loaded. Anyone come across this and if so what would be the cause? I am certain its a board issue since I tested the LCD on another board and it stays on. Again the backlight works...
