    Issues Reviving Old Dell 2408WFPb Monitor

    Hello everyone,

    I have been having some difficulties reviving an old Dell 2408WFPb PC monitor that I received for free. When I first acquired it, the backlights of the display were on but alas no image was showing. After extensive research on the topic, I went ahead and purchased a new t-con board for the monitor. After installing the board, I was then presented with a new screen that was half black and half green (more so black). I have been unable to figure out what to do next as I have limited knowledge of display electronics. Might anyone on this forum have an idea of what may additionally be going on with the monitor? I am open to purchasing another board, if need be, so long as it would not cost more than purchasing a new monitor.

    I have included several photos of the boards inside the monitor as well as the green and black screen.

    Thank you very much for the help, and please let me know if I need to provide additional information.

        Not really sure whats going on. For shits and giggles look that all the voltages are there (buck converters etc) on the main board and you can feed the monitor with a signal and look at the LVDS pairs with a 100MHz or better oscilloscope. Have something that changes pictures or make the OSD a come on and off all the time while probing. First you gotta be sure the main board is working.

          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...

          Dell 3100 Chromebook Power issues
          by JKetcham
          Hello, wanting to see if anyone has any experience with Dell 3100 Chromebook's and might have some input on an issue I've been seeing with them.

          I work in Technology for a good size school district, and we've began to switch away from Lenovo Chromebooks over to Dell 3100. I like the Dell 3100's because they seem to be more durable than the Lenovo N22's, N23's and 100e's we've used in the past.. but my main complaint with them is they randomly won't turn on.

          Currently, in my building I have about 200 students using the Dell 3100's and daily I have a rash of students...
