    LG Studioworks 775N monitor

    Hello All,

    I have an LG Studioworks 17 inch CRT monitor, model 775N. It is currently sitting in my shed. It was working fine a few months back, then one day, it started to click in operation, a few times actually, so i turned it off, then i went to turn it back on and it wouldnt turn on. It just clicks .... very loudly.... i can hear it degauss itself on bottup , then it will just click and turn off, and automatically reboot and do it all again, nothing comes onto the screen now, just a blackness. I was lucky once to get the words "Signal cable disconnected" for about 10 seconds, and it automatically turned off again, with the standby light in Amber.
    Im guessing that my flyback circuit is busted forever now?


    Thank You

    most likely PSU EHT as you suspect pm you some info
    hoping you haven't killed EHT

    Be careful in there, nasty bites or terminal case of "dead" possible


    even with plug removed
    HTH

    cheers mate

        Really was talking about when you replace things power it up turn it off cause it didn't work and go poking around inside
        but yes somethings can hold a charge for quite a while
        (ok maybe not months)

        The tube is a very good capacitor (of sorts) and when charged up from the EHT at about 25,000 ~30,000 Volts (25KV~30KV) can have a very high voltage stored across it
        See here

        When dealing with CRT EHT or SMPSU
        Always follow correct Safety procedures


        Basically not really a place for people with little knowledge to be in which is why the warning above.

        suggest you go here to read more about them and the safety section.
        This will give you an idea of how the TV works, crt monitors are basically the same but have different application and therefore are somewhat different in how they process the video signals and display it.

        monitors

        SMPSU

        I would probably just check, replace regs etc as outlined in PM
        but if its the EHT ....bin it probably not worth the cost of fixing

        Hope this helps

          Just an update.... Well I got rid of the LG CRT monitor earlier this year and got a replacement Diamond View 1770G 17" CRT monitor.
          Anyway, thanks for the advice Starfury1.

          Thanks.

            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...

            by ant3202
            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...
