    Backlight to repair LED panels

    Hi everybody. I am looking for ideas on how to go about designing and building a box wherein there will be a relatively uniform light shining out of it and onto some kind of surface whether it be a diffuser sheet i don't know. I need to start repairing panel faults where you bridge missing voltages on the side COF IC's. So you need to see what you are doing ,the panel would be placed on this lighting box upside down so that you can get to the side cof ic testing points but still need to see what you are doing hence the backlight.
    Any ideas?

      So a box with a clear plastic sheet on the top with LEDs underneath.
      Broken tv parts or make one using a cut up roll of LEDs and a power supply.
      A piece of paper on the reverse of the plastic will diffuse the light.

          Or maybe a tv whose led panel is cracked, we remove the panel and reassemble the set.
          Use the tv to diffuse the light that way?

              UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!
              by triplefour
              this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
              i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
              unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
              according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

              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...

              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....

              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...
