    ViewSonic VX1940w

    For the past few months, sometimes when my screen goes idle and I try to wake it up, it'll simply not come back. Restarting my computer always fixed that problem and since I'm lazy, I didn't care.

    Today is different. I was using it and realized it was starting to fade. Eventually it just blacked out and turned off. I restarted my computer and after fiddling with it I got it to show, but it's a very dim display. As if the lights are about to go out.

    I did some searching and apparently it's the inverter board? I can't seem to find a place that sells them. If anyone could give me some suggestions, that'd be a big help.

    But I'm also considering just buying a new monitor if it's going to cost too much to repair. So I'm also asking whether or not it's even worth it to try and repair my monitor or to just buy a new one.

    Also, this is a very new monitor. It's only a little more than a year old, so I'm pretty annoyed that it's already having such problems.

    Thanks!

    Hmmm, sounds like a bad science fiction movie. And you're the reanimator.

    It's repairable, but it might have been easier to repair a few months ago. (Don't worry, I know about procrastination).

    The first thing: What is your experience with repairs in general and electronics in particular? If an inverter is available it would probably cost over $70 plus shipping. In the other hand, if you are a victim of bad capacitors, replacement parts could cost about $10. Of course, you would have to solder them in.

    The first step is to disassemble the monitor and look for obviously bulging caps. Taking pictures and attaching them to your next post would also be helpful.

      I fixed a VX1940W-4 today.

      C202,C203,C212,C213,C310 are all 470mfd 25v.
      The 5 caps were a mix from 3 different manufacturers.

      C202 and C203 were TEAPO caps and had failed, replaced and back in business.

            Sorry for bringing up an old topic, but this both happened to my Dads and my screen - within a few weeks of each other (purchased at the same time).

            If anyone knows how to open the screen and how to fix it - for a basic beginner, me and my dad would be extremely grateful!

                OK, then what do I look for? Obviously I'm new for this. Do you want me to take high res photos of all the boards and post them on here? Or just the board where the sounds coming from?

                    Re: ViewSonic VX1940w

                    OK, I'll open it later; probably this afternoon. (British time)

                    Can describe the problem though.. Yesterday it started make a really high-pitch noise, coming from the back right corner of the screen. The screen then went black, like it switched off -but the blue power light still on. I switched it off, then on - the screen came back, but then after a shorter period of time, the same thing happened again. I repeated this, and then it was a shorter period of time still.

                    I then realised something was wrong and immediately unplugged everything.

                    Hope that helps. Thanks for the quick replies by the way! What part of Canada you from? My flatmates Canadian!

                              The screw holes in the back are utilized when the monitor is wall mounted as opposed to free standing on it's own stand.

                                its not your monitor in this video but your bezel will come off near enough the same way

                                  Ive managed to get most of the screen case of (see pic), but theres still something not prying lose.

                                  I think it may be some screws at the rear bottom of the case, that holds the case stand in place (see pics). Any idea how to get to these to unscrew them? At the moment they are under the plastic casing.

                                    It appears that the base needs to be removed before the rest will come off. The base is sometimes held on with screws, but sometimes it just slides on and snaps in place. I would check to see if the plastic part above the base will "pop" off and expose any screws beneath it.

                                      get a flash light and look straight down hollow part of the base,where the stand was snapped in,there's probably 3 or 4 screws holding it on.
                                      Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

                                        Thanks for all your help today, I'm sure I'll be back tomorrow with the damage

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...

                                          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...

                                          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

                                          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...

                                          4 weeks ago i launched Metro Exodus Enhanced and during cinematic advertisement part ( 30 fps ), pc just shutdown.
                                          Also monitor flickered with NO SIGNAL 10 seconds after shutdown. So only monitor and pc was affected.

                                          Next i pressed only power button, rebooted again and its fine again. Happened once and i cant reproduce.
