    The panel doesn't matter, just the number of lamps. Since the caps were in very bad shape the resulting ripple could have damaged something else.

        PlainBill, Th3_uN1Qu3, retiredcaps: thank you guys so much for your postings. So far I got inside the fully functional 19" Avidav monitor with some M190EN04 V.5 LCD-panel. This panel's connectors are different, but my HannStar could be somewhat exchanged with it. Now what would be the worst scenario if I connect my trial Gateway's HannStar panel to that power board and vice versa, any experience?
        Thank you in advance!

            Worst case scenario is you wind up with a destroyed power supply, signal card, and reputation.

            If the form factor, pinout, and output voltage of the power supplies are the same, the chance of success is quite high. If they are not, do you know enough to adapt them successfully?

            The point I always make is there are a limited number of faults that can occur on a power supply. MOST are repairable. Many are easily repairable with nothing more complex than replacing a half dozen caps. Unfortunately, there are thousands of ways of making a monitor housing. A difference of 1/8" can make two boards incompatible.

            For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

            Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

                Thank you Th3_uN1Qu3, PlainBill, and retiredcap, it was total success. I am enjoying this monitor right now.

                The panels have been bravely switched from their power supplies, but signal cords left their own since the plugs were completely different. Now the trick was not only of powering both boards simultaneously but moreover connecting both to signal, this way neither of them would unexpectedly turn to "sleep" mode (yellow led). The tested panel (HannStar, 4 lamps ) worked fine on the alien board (Avidav 19") and vise versa.

                My monitor as I believe now was already fixed after "solder everything through" move, but some trial errors and this sleeping mode prevented me from seeing proper performance.

                I am extremely grateful to all useful info I've got here. Thank you guys for maintaining this forum alive!

                    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
                    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.

                    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...
