    Intermittent flicker - LCD monitor

    Working an a '09? or so Acer, 22", I think. Random very slight screen flicker. Here's the thing; it may flicker off & on for a couple of days, & then clear up and not flicker again for a week.

    Initially, I had it in for a black screen/wouldn't power on. I replaced several bulged caps & went over everything very well visually, couldn't see anything else wrong.

    Ideas?

          Sorry!

          Should have included more info. I guess. I actually did replace all the caps. Guess I didn't word that correctly.

          I don't have any way to get pics at the moment. Just thought that by the symptoms I'm describing, someone might think of something.

          I did go over the boards with a strong magnifier & I have a good eye - I'm certain I did not notice anything else defective.

              Couldn't be the tube itself going bad?

                  Listen very carefully in a quiet room, hear any hissing or arcing? Could be a bad connection to one of the ccfls.

                  I'm assuming "going over the boards with a strong magnifier" includes looking for bad solder joints.

                      The monitor model # and photos of the boards would be helpful at this point.

                              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.

                              Wise Wing F199 19'' LCD monitor - recapped
                              by momaka
                              Looking through my repair pictures and notes, it's been a long time since I posted anything in the LCD monitors section. So here goes that.

                              I'm dedicating this thread to one of the very first LCD monitors I repaired (if not the first one), which was more than 10 years ago now. The monitor is a Wise Wing, model F199. It's a 19” CFL-backlit LCD. I got it for free off of Craigslist in 2009 from a guy, who said he bought it for cheap from Wallmart and the monitor worked only for a little less than 2 years before quitting.

                              When I saw the Craigslist post, I wasn't...
