    Re: ViewSonic VA903b

    The results are not much use without the part number to verify what they are meant to be. U4 and U7 are probably ok - you have presented the results
    in the wrong format -

    "3) Put your red probe on each of the pins including any "cut" or "stub" pin, but ignore the "fat" tab. The fat tab is "up" or "north". Number the pins left to right.

    4) Report them like below along with the part number (include all lines on the IC) of the IC. Don't report "they all tested good". About once every 2 weeks, we get someone who reports that only to find out they did the arithmetic wrong or mis-interpreted the results. So report all the readings."

    If you are still online you may be able to edit the results in which case I will edit this out.


    U100 -> pcb designation
    AS1117-33 -> line 1 of the IC
    0506 -> line 2 of the IC
    pin 1 = 0.000
    pin 2 = 3.301
    pin 3 = 5.001
    Please upload pictures using attachment function when ask for help on the repair

      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...

      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...
