    Re: HCL moniter

    Are you saying the pc doesnt detect the monitor.
    What does monitor do when switched on - power led? screen flashes?
    Cap at bottom right on power supply looks bulged to me.

      I see at least one bad cap on the power supply-inverter board, you should replace them as a set.

          Svga is fairly standard it has changed slightly through the years.
          Google "SVGA Pinout" and go to images there are lots make sure you get the one for the
          plug and not the socket or it will be wired in reverse. Is the model number not on the back of the monitor or on a label inside the back cover?

            I see Xunda brand units inside - a known bad brand of electrolytic capacitor.
            My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

              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...

              Hi Everyone

              Lately I am experiencing the deja-vu incident on one of the led monitor like this.

              The monitor is HP 27es LED Monitor

              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...
