    Dell 2407wfpb Monitor Flickers and Dies

    Hello everyone! I looked around on the site and couldn't find a problem similar to mine, so here goes.

    About a month ago, after using this monitor for about 2 years with no problems, I was gaming on it and it flickered (screen went black) once. It didn't do it again, so I forgot about it, and then about 2 minutes later it did it again. And then with increasing frequency until in about one minute my screen was completely black, with very occasional faint flickers of the screen appearing. I rebooted the machine, and after about 30 seconds it began doing it again!

    I let it "rest" overnight, and started it up the next day with no problems. For the next month or so it would exhibit this same behavior after an hour or two (or more - Civ V is a time-sink!) and I would shut it off to let it think about what it had done.

    However, yesterday it did this again and I haven't been able to get it to go more than 90 seconds since without it flickering itself to death.

    I tried the flashlight on the screen trick to check for a backlight issue, and am pretty sure I couldn't see anything. The monitor is still powered on, and the rest of the computer is running fine. The cable is securely connected on both ends. And that's about all the troubleshooting I've felt capable of doing without some assistance to make sure I don't trash the machine.

    I appreciate any help you can give me, and have patience as I am new here. Let me know if you need more information or I'm not following one or more rules.

    Thank you all!

    Off topic - I went to school in Renton

    On topic - You should post some pictures of the boards. It's possible it's just caps (hopefully), I know Dell liked to use Su'Scon caps in some of those monitors. But it could be an inverter or loose CCFL connectors too

      Okay, I've got it taken apart as completely as I can. I don't see anything obviously wrong with the electronics, but I'm pretty new at this.

      I'll have to wait until the wifey gets home for use of a camera, but while I've got it apart, is there anything I should try?

        Do you have a multimeter?
