    viewsonic vx1940w losing backlight

    hey guys. Just got this given to me...

    sometimes it takes 2 secs, sometimes its after a couple mins, the backlight will abruptly shut off and power has to be cycled to get it back.

    usually the longer its on the worse it is. Geting ready to tear it apart now, im really hoping i find a couple krappy caps.

    When working the backlight looks good its not pink or anything...

      and were golden..

      on this model the power supply is also the inverter. A nice SIMPLE setup, very minimalistic.
      There were two vented and DRY 2200uf/35v caps.

      Replaced and viola its good again. Been on for a couple hours now and going strong.

          Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
          by lostone
          Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

          First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
          When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

          UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!

          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...

          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...
