    MACBOOK PRO 820-02100 BACKLIGHT ISSUE


    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?​

          The macbook was one that I bought few month ago that I used with an external screen . Now I started to do some analysis on the MB which my limited knowledge .
          First thing is that it suffered from liquid damage . The fuse was not ok when I openned it the first time . But I already changed it after testing that there is no short to ground on this line .

          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.

          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...

          Thomson 50UD6306 (TCL) Backlight Issue, starts then stops, led changed
          by Cornito
          Hello Team,

          I'm back with another backlight issue that I thought was simple, but it turned out to be more complex than expected.

          Let me provide a brief history: The TV was working well, then one day, the backlight started and shut down. I thought I had an LED issue leading to this behavior, so I replaced the LEDs with brand new ones. However, the issue remains the same.

          Next, I replaced the electrolytic capacitors attached to the LED power supply, but the results were the same. I then replaced the driver, a OB3365RP, and did it twice due to the same result....

          Macbook Air 1466 Backlight and Fan Issue
          by Instafixx
          Hi,
          I have a Macbook A1466 820-00165 with a Backlight issue and Fan Spinning Fast.

          To Elaborate, the Apple Logo used to come on for a few seconds and the become dim. Somtimes it used to stay on till the password screen.

          So we replaced U7701 and the Backlight issue is resolved. But the Max Fan Spin is still there.

          Tried replacing the LIO Cable and LIO Board but still its there.

          After a few seconds the FAN starts spinning at Max Speed. I guess the CPU is throttled too as the it becomes really slow. The board...
