    Cold start issues I-inc iF281D

    I am pretty sure my issue is cap related but thought I would ask before I rip in to my monitor. My issue is when my office is Cold in the morning(temp setbacks to about 12c at night) my monitor power button does not work. Once the office is warm or I warm the back of my monitor it turns on no problems, or if the I override the temp setting for the night it all works fine.

    I have just never experienced and issue related to cold so not 100% what could it be.

    Sounds like it very well could be related to the capacitors. As capacitors age and start to fail, their ESR goes up. As the temperature of the capacitors rise, the ESR lowers and may allow the monitor to function as expected. This usually gets more and more difficult as the capacitors continue to fail.

    Open up the monitor and take a look. Post pictures of the front and back of the power board (and logic board). Use manage attachments below the text area and do not post the pictures inline.

    There are several threads concerning this monitor with one of them having posts within the last week. You might want to look through them to see if anything pertains.

        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...

        Issues Reviving Old Dell 2408WFPb Monitor
        by Jesus Coder
        Hello everyone,

        I have been having some difficulties reviving an old Dell 2408WFPb PC monitor that I received for free. When I first acquired it, the backlights of the display were on but alas no image was showing. After extensive research on the topic, I went ahead and purchased a new t-con board for the monitor. After installing the board, I was then presented with a new screen that was half black and half green (more so black). I have been unable to figure out what to do next as I have limited knowledge of display electronics. Might anyone on this forum have an idea of what may...

        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...

        I need help with my friend Sony GDM-FW900 24” CRT
        by matthewmcconaughey
        Hello, Badcaps is my last resort. I am the first owner of the monitor. I reached almost every repair store in my area, but no one even wanted to hear about troubleshooting an old CRT monitor. At this point, I have been trying to figure it out by myself, but I have no idea where to start or look for.

        I wish to know how to think and locate a failing component. I will put all my efforts to learn and contribute.

        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.
