Question about ViewSonic VA712B 17" Flat Panel LCD Monitor

Viewsonic VA712b 17 " flat screen monitor

I just bought this monitor today, and can't get it to work. It worked for about 2 minutes, then began to flash back and forth from the screen to a black screen and then finally just went black completely. If I don't wait and try again immediately, the screen is totally black. If I wait a bit, it does the screen changing thing and then goes to black. I should mention that when the screen is lit, it seems to be shaky, as if some sort of current/disturbance is present. The computer I am using is a DELL Dimension 3000. Thing is, it seems to work fine when I plug into an old laptop (also a Dell) that I have. What's the desktop PC missing that the laptop has got? Or what's going on here? I read several of the other tips, but did not seem to see any that had to do with a brand new monitor... thx-

Thanks so much for the advice. Unfortunately, nothing worked. I was on the phone late last night with more comp savvy friends, NONE had any clue, seeing that since I was using the VGA connection, and had used a similar monitor before, things should have worked. I uninstalled drivers and reinstalled drivers... changed the parameters as you suggested and still... no go.

Sooo, today I took that one back and exchanged it for a VGA only, little larger widescreen (Viewsonic VA1912w 19") and brought it home, plugged it in and all is good. So the DVI port was not able to be recognized, even though it was not being used??? I don't know. But for the time being, I'm happy.

I am still a little weary about viewsonic, even though I can't really afford to be. The monitor that I just brought home had a power supply cord that I think is for Egypt. I am in Sweden. Thankfully, I have extras lying around.

anyhow, thanks for your help. I'll let you know when it explodes or melts or something.

my viewsonic Va 712b has no sound

VA712b - display disappears within 5-10 seconds. Recovers for short time by PC reset or monitor power cycling. I am an experienced hardware engineer, working on DTV projects for the last 7 years. I have a 17" LCD monitor Viewsonic VA712b (Model number VS10901, S/N PX7062700927), which I purchased in California several years ago (the warranty is not valid any more). Since yesterday the display disappears within about 5-10 seconds. Playing with the VGA cable does not recover the display. The display appears when I reset the PC and by toggling the monitor state to STBY and back to ON. In both cases it disappears after short time. I verified that this is a monitor issue, as it happends when the monitor is driven by either my PC or my laptop. I also disconnected the AC input to the monitor for 2 hours, but the problem was still there when I turned it on again. 1. Can you identify the problem by the above description and suggest a solution? 2. If not, please provide me with instructions for openning the cover so that I can access the electronic boards and maybe identify bad solder or damaged part. Thanks, Dov Porat.

Using a ViewSonic VA712b LCD monitor. When I come in to use the computer and the "power save" feature is on, the screen, of course, is dark. Typically, all I have to do is move the mouse or type on the kb and the monitor comes on. Lately, this is not working. I have to shutdown the machine with the front power switch and actually toggle the switch on the power strip before I get any video. I'm using Windows XP pro on a clone computer.

Realheadache, Unusual problem, it could be the resolution and refresh rate setting your PCs video card is currently set at. I don?t know if this will fix your problem but its worth a try: - Now go to your PC with the old monitor connected, right click anywhere on the desktop. - Left click Properties from the box that appears. - When the Display Properties box appears click on the Settings tab. - Make note of the screen resolution. - Change the screen resolution to 1024 x 768. - Click on the Advanced button in the lower right hand corner. - In the next box that appears click on the Monitor tab. - In the Monitor settings section of this page record the value of the Screen refresh rate. Then change it to 60 Hertz. - Close this and the Display Properties box by click on the OK button. - Now try connecting your new monitor. Let us know if this helps and as always please don?t forget to rate this posting.
