    Dell 2408WFP no picture

    Hey, everyone, I got this monitor for free and It was working fine and then I had to unplug it from the power and when I plugged it back in I was greeted with a messy white screen and not able to switch inputs or see the OSD menu,

    now I dont get a picture at all and if I hit the side of the monitor the picture would blink like it is trying to correct itself but it does not do anything

    I took it apart and checked all of the caps and none looked bulged or anything but now when I turn it on I get the green led on the power button and a black screen but I can tell the backlights are working

    so it still does kinda work but I cannot get a picture of any kind, does anyone have any ideas what the issue might be?

      Check all caps for both capacity and ESR. Even though they look OK, they might not work properly. At least because of high ESR which you cannot identify without testing devices. If your display is 10+ years old I would begin with them. Also, if there is a bad cap it might cause something else to die, so diodes or whatever goes next also should be checked.

              For what it is worth in case this thread is still live.
              The problem described by the poster is identical to what is covered by this thread:
              https://www.badcaps.net/forum/printt...?t=18189&pp=40
              A work-around is provided here.

                  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

                  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...

                  Philips 243v5lhsb00 Monitor Picture too bright
                  by Schwoin
                  Hey everyone,

                  the picture on my philips monitor looks way too bright so that black appears grey and colors also seem too bright.



                  While i tried to tilt the screen a little bit while it was displaying a picture, i´ve noticed, that there appeared some purple pixels. In the following picture
                  you can see them on the top half of the photo.



                  At a certain point during the tilting, the picture looked normal again but as soon as i laid it back down, the purple pixels were gone and the picture was bright again.
