    V7 r19wps no backlight - cfl lights

    I have a 1440 x 900 monitor which is a V7 r19wps.
    there is no backlight but on poweron i can see no video message before it goes back into standby using a flashlight.

    i've taken it apart and the power/inverter board and logic board look fine, and so i removed the power board and had it on the desk to force bl-on (to be sure). i jumped 5v to blon pin and no backlight, though it got quiet. so next i tried one of my test cfl lamps, and it glowed (only tried 1 of the 4 ports).

    this does mean the ccfl inside the screen has gone bad, yes? i'ved replaced one ccfl before, this looks to be a little easier to get to. but do you think it could be anything else and whether it would be worth it?

          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...

          Design of CCFL Backlight Inverters with Frame & Bar Cores

          Summary

          Portable devices, such as notebook computers and personal digital assistants are developed rapidly nowadays, which places an increasing demand on display technology. The LCD with cold cathode fluorescent back lighting satisfies the requirements on display performance, size and efficiency.

          The backlight inverter plays a crucial role in supplying the power to the lamps of these flat-panel displays.

          The frame and bar ferrite cores, described in this brochure, are especially designed...

          Sony XBR-75X950G seems dead with a black screen but backlight and sound is working and no blinking red lights
          by Audeze
          I have a 2019 75" x950g, and while playing a movie, the screen suddenly went dark in a weird way, where it faded towards one corner into being fully black. Now the TV turns on, and the backlight comes on, but there is nothing displayed except black. Sound still comes through the TV speakers, and i have tried doing a hard reset using the volume - and power buttons while plugging the display back in, but it did not fix it. I can confirm that pressing buttons on my remote is still doing "something" because I'm hearing sound still, even though the screen is black.

          Does...

          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 Flatron 24EN33TA No Backlight When Cold
          by canadaboy25
          Hi all,

          I've got an LG Flatron 24EN33TA with a backlight issue. The problem began with the monitor not powering up after sitting for a long time (overnight or during the day throughout work). When I would wake the computer up, the backlight would flick on for a second then go out. Sometimes it would take many tries to get it to come on. Once the monitor came on, it worked flawlessly until another long duration of being powered off.

          I thought the problem would be bad caps but I checked both of the caps on the board and they are fine. I also tried powering the monitor from...
