    Help with eMachines E19T5W LCD

    This monitor was gave to me and wouldn't power on because of bad caps. I replaced all the caps on the power supply and now the monitor will power on and display perfect for a few seconds, but has an issue like its losing signal feed from PC once Windows loads. I'm using the VGA input because my PC doesn't have DVI outputs.

    It will display correctly till Windows loads the Welcome screen and then it will go black a second or two, then display the test screen "no signal" icon, then go black again a few seconds, then display the Welcome screen with the "VGA Input" icon. It will repeat this over and over. While its doing this the power button and menu buttons are non responsive.

    Anyone have a clue?

          In another thread, this was due to the computer being set to a refresh rate the monitor couldn't handle. Some LCDs accept 75Hz, most want only 60Hz. Also check that the resolution isn't higher than the monitor can handle.

              Thanks for both replies. I 1st tried to boot into bios and let it sit there about 20 seconds and it started to repeat the issue so that eliminated a Windows setting. I took it back apart and recapped the control board as suggested and it now has been on the desktop for 15 minutes without any issues and the menu controls work great so that was the problem.

              The control board had about 12 tiny caps made by Teapo . They ranged in value from 10uf, 22uf, 100uf and one 220uf.

              Thanks for the help, and after a complete PSU and control board recap, monitor is now working.

                      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...

                      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...

                      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

                      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.
