    Westinghouse l1928nv

    Hello All,

    I recently acquired a Westinghouse l1928nv monitor. Some smuck previously
    tried and failed to repair the power supply board. When they replaced some
    caps with 470uf/25v even if they weren't that value to begin with. Maybe thats all they had access to? I want to install the correct value cap in this area instead. Maybe someone on this site knows the correct value caps in the area that I've highlighted in a red box? Any help would be greatly appreciated!

    Thanks As Always,
    Lcdman

      Hello Again,

      I haven't heard any one come forward with any assistance. Perhaps someone knows where to get a free service manual for this monitor using this power supply board.

      Take Care,
      Lcdman

          Can you post some pictures of *your* board - front and back, please. I think I see some labels under the black connector on the right. That could possibly give you the voltages this monitor produces, so then we can pick the right caps.

          No, I don't have this power board, but if we know the output voltages, we can choose new caps according to that. Monitor PSUs are not awfully picky about capacitance, as long as you get it above a certain minimum.

              Westinghouse L2210NW LCD monitor - bad caps repair
              by momaka
              Here's another LCD monitor repair: Westinghouse L2210NW.
              Quick specs: 22” CCFL backlit LCD, 1680x1050 max resolution (16:10 aspect ratio)

              I got it with a bunch of desktops PCs from a repair shop that was trying to free up space a few years ago. It seemed like a cheap monitor, so I didn't really care that much at first when I picked it up (and indeed it is, picture-wise.) But hey, free is free, so I can't complain. Moreover, it looked clean and the screen didn't have any significant scratches or blemishes.

              Pictures of the monitor outside/case after a brief...

              AOC AG493UCX 49-inch monitor - Firmware request
              by wattage
              Hello Badcaps Community,

              I purchased a preowned AOC monitor that is not working and out of warranty. It was sold as not working. I am looking for guidance on self-repair. In particular, I am after the firmware for the monitor. At the end, I have included monitor model information and links to pics and vids of the issue.

              The problem is that it will not display a picture on any of its inputs. And the on-screen menu does not appear. The power button works properly. It powers on with the remote as well. But the on-screen menu does not appear, even when not connected to any...

              HP 27es - LED monitor - Monitor Flashing On - Off
              by ant3202
              Hi Everyone

              Lately I am experiencing the deja-vu incident on one of the led monitor like this.
              https://www.badcaps.net/forum/troubl...lashing-on-off

              The monitor is HP 27es LED Monitor
              https://h30434.www3.hp.com/t5/Deskto...e/td-p/6804692

              The monitor will randomly blackout and display no signal and will recover again.
              Sometimes need to power and off again to restore the display but...

              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.

              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...
