Question about ViewSonic VG2230WM LCD Monitor

1 Answer

Blank Screen Viewsonic VG2230wm 22" monitor. For the last few weeks I have been noticing that when I turn the monitor on it would bllink and go out. When I turned the montitor off and on again it would work fine. Then while in the middle of working on my computer the screen went black. I noticed that the blue light was still on, I turned the monitor off and back on but the screen remains blank. I shut down the computer and the monitor and let them set for a few minutes then turned them back on. The monitor light turned blue indicating it was on but the monitor did a quick light screen that turned black. Could it possibly be the connection in the back of the monitor? I operate my system using the DVI cable input. If that would not be the issue, I could use some ideas as to what I should check next. Thanks!

    Could you tell me the easiest way to get the back off the monitor without breaking it? I have removed all the screws and I noticed a small slot with a padlock symbol on it. I have check to see if there is a lever I need to press but have found nothing. Seems like there is a trick to separate the cover, can you please let me know the trick. Thank you!

Common problem in monitors are bad caps in the power supply, that is the first place to check, look for bad caps with bulging top/bottom, see example of failed VIEWSONIC monitors due to bad caps here (worst case will be bad lamps): http://s807.photobucket.com/home/budm/allalbums

    You will need flat blade screw driver or a strong tweezer (I use tweezer most of the time, see my tool album at photobucket.com). You will start at the bottom section of the monitor first, then work it all the way around, it is hard to explain. By the way, the locking key symbol is for theft security hook.

There are almost always plastic clips along with the screws. I'd recommend buying a plastic pry bar. You can google for them online and they cost $1 or so.

Viewsonic vg2230wm - the screen is blank when the computer first boots. I have to turn the monitor power switch on/off several times before the screen turns on, then it is fine.


Check your VGA (Visual Graphic Adapter) connector from your C.P.U (Central Processing Unit) to your monitor if it is intact. If it is intact , replace the VGA cable first. Then if the problem still persist check for the VGA driver in the device manager if it is correctly installed. If the problem persist try and send mail to me on greatengineerid@hotmail.com

My Viewsonic VG2230wm refuses to use its native resolution of 1680 x 1050. Whenever I select this resolution, it registers on the computer display settings, but when I check on the monitor display panel...


You will need to adjust your monitor settings in the NVidia control panel. You can get to this by right clicking somewhere in a blank spot on your desktop and then selecting it from the menu. You will want to go into the Display section. If you aren't able to see that section, change from "Standard" to "Advanced" settings at the top of the screen.

Vg2230wm monitor Will not power on


probably your power supply. Is it a cord direct from plug in for is there a box between where you plug it in and then a small round end that goes into the monitor. This would be the good news. If it plugs in direct then that means the power sopply is in the monitor itself which means more expensive to fix

Black screen, power button flicks


The monitor should come when the power button is pressed once - period. If not, and it continues to happen when connected to another PC, then the hardware is having trouble powering up the panel / ccds and it should be replaced/serviced according to the terms of the warranty. I suggest to bring it to an authorized service center for proper diagnosis & fix the problem. regards
