    Test dusplay "backlight only" A1297 macbook pro 2010

    Hi

    I have image but no backlight. Fuse is blown. I think the display is faulty or cable lvds.. but not shorted last 3 pins in connector to GND
    .. Can I test the screen backlight only unplugged from motherboard with 32v at those pins? (Expecting to see a backlight only)?

    You won't see any operating screen voltages if the screen is disconnected. Check for shorts at the screen connector for backlight with the screen connected (no power obviously) and disconnected to make sure there is little or no difference. Replace the fuse once confirmed to check for proper voltages.

      No Backlight Macbook A1990 820-01041
      by Comp_Pro
      Hello all,

      Am trying to figure out this backlight issue with this A1990 Macbook Pro.

      Tests performed:

      There is no backlight even with a good screen.
      Backlight IC is receiving the correct support voltages.
      Fuse F8400 ok
      Current sense resistor R8400 ok
      Backlight IC is receiving 3.3V on enable pin.
      Backlight IC receiving voltage from PPBUS_G3H, aprox 12.5V.
      Backlight IC receiving 5V from PP5V_G3S
      Backlight IC BKLT_SCL and BKLT_SDA both measure 0.545V diode mode to ground
      I2C_BKLT_SCL and I2C_BKLT_SDA both measure...

      Macbook Pro A2442 820-02098 No image but has backlight
      by Constantinos
      Hi all
      I have a Macbook Pro A2442 with the 820-02098 from a friend which has no picture on the display, however, the backlight works.
      He was streaming a football match on a questionable site, then the site crashed, and the problem emerged.
      Initially, he sent it to apple, who quoted him £1323.95 to replace the display, lid angle sensor and top case.
      Obviously, he decided against this and gave it to me so that I could have a crack at it.
      From initial diagnostics, I connected to an external monitor, I first tried with a HP 22W monitor, and I booted into the boot menu...

      MacBook Pro A1909 LCD (no backlight)
      by francescoranchi
      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...
