20 Most Recent ViewSonic OptiQuest Monitor Questions & Answers


At a guess it is the refresh rate the video card is sending to the video out. What is the Max Resolution of the monitors and refresh rate ??
I would think there is a program to be able to setup the driver refresh rate and resolution don't use window drivers get the ones from the makers of the card rather than using the default nivida drivers

I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.

I'd like to report a success story. I had this same problem with my Q20WB. It sat for over a year in my garage. I eventually bought replacement capacitors, soldered them in, and now it works. You can find kits with the right capacitors preselected, or if you feel like it you can also buy them individually.

good luck

Sounds like you may have broke at least one of the lamps . The high pitch sound you are hearing is the high voltage that goes to it .

Look for bad caps with domed tops as shown in my Optiquest Q19WB (VS11443) here: http://s807.photobucket.com/albums/yy352/budm/Optiquest%20Q19WB/

Please read my guide before DIY repair.

You need to inspect the power supply/inverter bd. first.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Optiquest monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Hi Rickyknows2,
If you are not hearing any beep I assume you are having problem with your video so, please ...
- open your PC and check whether your video card is well placed (sometimes it looks fine but you never know) remove it and put it back.
- If you used to remove often the cable from the PC, it might be that the pins from the monitor cable are even broke... please check.
- try to find another video card and replace it just to make sure its the video ...
- last... reset the bios (but I doubt that this is your problem)
chsers ..

Open it up and look at the capacitors. The round "tin can" looking components. If the tops appear bulged, then replacing them may help. Check out the YouTube video... and web site...

REPLACE CAPACITORS IN POWER SECTION

ViewSonic... | Answered on Mar 21, 2010


After 2 years, more likely the caps will be bad by now, worst case will be bad lamps, open it up and look inside for caps with bulging top first, see example of failed monitors due to bad caps/lamps: http://s807.photobucket.com/home/budm/allalbums

From your description, it sounds like the internal 5 Amp cartridge fuse is open. Will need to open the housing and inspect the fuse for failure. If located and failed, replace it and energize the monitor.

If the fuse fails immediately, you have a High Voltage power supply short and the monitor is scrap. It will cost more to replace the power supply/transformer than the monitor is worth.

Hope this provides some useful information.

On mine I pulled on the round cover where the base attaches to the screen. It came off and there are 4 screws underneath. Remove those screws that hold on the base
