    Hi, This laptop came as broken lcd. I changed the lcd but there was no backlight. It is ok on external screen. What i have done so far is;

    I changed the inverter
    I changed the ENE controller
    I changed the Lcd flex cable

    Still no backlight. The measurements are below;

    Inverter 4 pins as in standbye state

    1- 18.7v
    2- 14v
    3- 0.17v
    4- 15.7v

    Inverter 4 pins as in powered state

    1- 18.2v
    2- 13.8v

      1- 18.5v
      2- 3.3v

          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....

          Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
          by DanPoka
          I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
          Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
          This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...

          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...

          lg 32LC46 backlight inverter board fault
          by jimbofz
          Hi this oldie had no backlight .after replacing caps on 24v rail ,
          still no b/l this uses inverter type:1315 B1-16A,
          im sure ive come across the same inverter in a samsung possibly le32r88bd ?
          all t/x in board test ok ,so i fitted 15k and led to pin 4 of oz964gn ic
          this allows protect to be temporary overridden.
          b/l now comes on
          but the left hand side of pic is gradually darker than the right side
          i have the cct for the tv
          but it does not have inverter cct.
          i opened it up to inspect the ccfl tubes
          and they dont have any...

          iPad Pro 12.9 5th Gen Backlight Issue
          by cheebster
          Hello, got an iPad Pro A2378 12.9 5th gen with no backlight. Got another test unit without screen, tested the screen, still no backlight with the test unit.
          Figured out the backlight on the screen was bad, ordred a new backlight from mobilesentrix, *carefully replaced it* without damaging the lcd, oh well.
          Final result, issue is still there, the screen has no back lights. So i'm back to square one, with 3 hours less and 100$ out, issue still on the screen.
          The panel is still ok, i can see the apple in the middle of the screen when it kicks in, just no backlight.
          Anyone...
