    Hanns-G HG281D issues again

    Hi,

    I thought I would start a new thread since I didn't want to hijack an existing thread.

    My symptoms are that after re-capping the power supply, I used the repair kit found on Amazon, my monitor worked for about 4 days, then last night it up and died. Nothing I could do could make it work. I thought I turned off the monitor, but when I came down this morning I found it on with a blue power light. I then attached a cable and could see a web screen I had up on my laptop which I left on last night. As of now, what is happening is that the monitor will work for a couple minutes at a time and then go black. The power led begins to flash ever so often, and then it goes amber to signify it has no signal. When I re-attach the monitor, it will flicker for a moment or two, the display the screen, and then a minute or two later go black again. Wondering if the logic board or the voltage regulator could be bad at this point?

    Any ideas?

    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...

    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...
