    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?

          Seeking Advice: Repairing Dell U3425WE Monitor with Faulty USB-C/Thunderbolt Ports
          by Borse2008
          Hi everyone,

          Looking for some advice or opinions on what to do with a monitor issue I’ve run into. Apologies in advance is this crossovers a few forum categories.

          I have a Dell U3425WE, which I've recently replaced with another model. That said, the original unit is still fully functional in terms of the display — it works perfectly over HDMI and DisplayPort. However, the USB-C and Thunderbolt 4 ports have stopped functioning correctly. The Issue:
          • The 90W Thunderbolt 4 port (circled in the photo) no longer charges or powers any device, including laptops or MacBooks.
          • There’s

          LG 23MP55HQ LED Monitor turns off after a few seconds or flickers.
          by Rick_1234
          Good evening, gentlemen.

          I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

          To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

          Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
          by Bowline
          My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

          Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

          My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
          The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
          I have tried multiple different Dell power adapters. My Dell...

          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...

          HannStar Hanns-G HC194d LCD monitor repair
          by momaka
          Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
