    Re: Dell P2412h LED monitor shows pink tint in white screens

    Thanks, Ifixstuff9, I was told by a tv repair guy that it's probably the T-Con board along the bottom of the panel, and not repairable (I tried to separate one once and of course just split the glass open as well) and not worth fooling with for a $45 monitor used. But it may be the LED as well; I had an old Sony clock radio where the LED display got dimmer and dimmer over time until you could only see it a bit at night so they can just wear out. Either way, it seems to be the panel that's the problem. I'll keep watching for a dead one with a good screen or sell the boards out of it I expect. Thanks!

      look at the light shining through the translucent parts of the panel back.
      or through holes.
      normally led backlights look like daylight fluorescents or 6500-8000k.
      i had a 24" samsung with the connector broke off the strip that i repaired.
      when i tested the strip i notices the color was about 5000k with a noticeable red spike.
      but the monitor looked perfect when i reassembled it.
      its far more common though to fade to a dim blue.
      just fixed some off road led lightbars for a neighbor that were very dim blue after a years use.
      cheap noname leds.
      at least they were 3535 type and i have a ton of nichia 219 on hand.

        i almost forgot.
        pull the lvds and power up.
        is the screen now white?
        or is it pink?
        white means the backlight color is ok.

          I will try that with the cable pulled as soon as I get a chance.

            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...
