Question about ViewSonic VA712 17" LCD Monitor

LCD monitor screen blue

Hi! Just bought myself a new Viewsonic VA712 monitor yesterday. It worked fine last night, however this morning when i switched it on, the screen started to shake, and then everything turned blue! icons, pictures, everything! no colour except a deep shade of blue! The only change I had made was in the screen resolution, (i made it smaller)-- Someone told me I should reinstall my VGA card. I have an nvidia geforce 5200 (? I think!) card. Help, please!

Either the VGA card or the monitor can not display the resolution correctly, so you need to get it back to where it was, this solution is for Windows users (not sure about other OSs), reboot your system and and get in the options start-up screen by pressing F8 at boot, choose safe-mode with VGA, if you see your desktop normally here then it's definately the screen resolution, set it back to a lower resolution (try 1024X768 and go downwards until it works fine), restart your system normally and you should be able to test new resolutions again, if it won't work using VGA mode then you might need to uninstall your VGA card but make sure that you have the correct driver for it before uninstalling, also please disable any onboard graphics card if you have one. I hope this would solve your problem, please feel free to ask if you any further questions regarding this matter. Thanks

Other than hardware problems, the shake u mentioned might be due to magnetic interference. make sure any adapters for speakers or modem are kept in a place not nearer to the monitor

I had posted my problem in 2006. Everything is fine now, thanks. The problem was with the connectors behind the monitor. I think they were not fixed properly. Strange that it was such a minor thing --- :) Thanks everyone for your help.

    I was having the same problem and thought my monitor had gone bad since it's a few years old. Check the connections, and sure enough that was the problem! Phew, thought I'd have to crank out $$$ for a new screen.

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.

This also happens to my vga connection to my TV.
I used my tv remote "auto" button to re-size it to fit correctly.
If your monitor/TV does not have the adjustment, you may need to
supply your vga compatible device with your monitor's driver software.
This tells your computer what monitor specifications you have.

My VA712 does not turn on, when supply button (mains) not from front panel, switch ON it shows blank screen (no sign of turn on) but when repeatedly switch ON & Off it Turns On & shows the display....


bholesir, If unit covered by ViewSonic warranty, USE IT!!! The units "switch-mode-power-supply" is in need of service!! Unit WILL require inspection and repair of possible bad (poor quality soldering) soldering of electronic components to the prinded circuit cards and or need replacement of bad (poor quality) electrolytic filter capacitors on the unit's "switch-mode-power-supply"/"CCFL inverter circuit" that have failed!! Do a visit to YOUTUBE for "LCD monitor disassembly" and "LCD monitor repair" so you can familarize FYI with what is inside your monitor, and possibly make a decision to do a DIY repair or contract out the work to a local TV/LCD monitor repair shop. If your pocket is deep enough, maybe you will repair and buy a new unit, keeping VA712 as spare unit for a rainy day. Read more of my responses to other owners in my FIXYA profile for more options not mentioned here. Good luck with repair. 12fixlouie

I had the same problem, you must call Viewsonic to change your screen. The DVI input on the screen is dead.
