    820-00165 No back Light

    Hello,
    Namaste!

    I have a macbook A1466 that came in with no booting issue.
    Looks like something exploded in the Backlight circuit. (Image Attached)

    L7701
    C7799
    C7797

    All of these were totally gone. Rest of the board was fine. No Green.
    Replaced these components. Board boots up now but there is no Backlight. I get image - Apple Logo - Password Screen. But no Backlight.

    Getting 3.2V P3V3_S0SW_LCD_UF checked L8304 Pin 2.

    One more thing i noticed that the Charging light is also flaky. Goes off/onn randomly (On both genuine and copy charger)

    PPBUS_G3H is at steady 8.58V

      Lift Master Garage Door wall switch display / motion sensor controller display disappeared no back light
      by sam_sam_sam
      This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

      I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

      I am comparing them to a brand new one that I installed

      The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

      I going to let it run for several days before I remount back on the wall next to the...

      LG 47LA620V Same LED Failing Back Light Issues
      by jdawg99
      Hi All,

      I need some help with this one please. I am attempting a repair on the backlight. TV turns on and flashes the LG logo so stripped it down and found one faulty LED. Replaced it and tested on an LED tester and the strip was good. Put it back onto the PSU and it lasted about 20 seconds before going out again. Same LED had blown. Changed it for another type of SMD one (same voltage) and it seemed fine. Put the TV back together but it was quite dim. Noticed it was in power save mode so turned it off and the screen was bright. Left it on for half an hour only to come back to the...

      Problem

      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
