Are you plugged into the right Line Out port on the computer? Is the volume icon muted?

I had this problem with my Q9 and I was glad to find the FixYa website with help. But I will offer more detailed info for novices to make sure you find the capacitors. First of all, it is not easy trying to find out how to open the monitor up! First, set it down flat on it's face, being careful not to scratch the screen. Pop off the cap that covers the stand mount to the screen. You might also want to remove the base by squeezing the bottom tabs to the middle and pushing them out. Once the base cover is removed, you will see the 6 screws holding the base arm to the screen. Remove those and the arm will come off. Now, on the bottom right, there is a beveled slot where you can fit a flat bladded screw driver to start to snap open the case. Move around the case separating it carefully until it is completely un-snapped. Unplug the speaker cable (mine gave me some trouble but I worked it side to side and it finally let go). You can push the videop cable through the the back case to get the case out of the way. Once you have removed the back half of the case you will not immediately see the offending capacitors. You will need to remove 4 phillips screws holding down a metal shield on the power board. You may also have to remove some metal tape covering 2 of the screws. When the screws and tape are removed, you will need to slide the metal shield to the right to release it from a 3 pin connector that the two boards. Be careful that you don't damage that connector. Lift up on it a little and slide it left until the connector is disconnected. Now you can see the capacitors. I only had to replace the 3 bulging ones and that fixed my problem as well. Thanks all for your helpful comments in saving me money on a new monitor!!

Look for bad caps with bulging/leaking tops as shown here:

Very common problem in all LCD monitors as you can see in my albums.

The best way to clean an LCD monitor is to take a lint free cloth and spray it with Windex or vinegar and water solution, or in a severe case, summer windshield washer fluid (the kind meant to remove insect guts). Make sure the cloth is DAMP, not WET (we don't want anything dripping out of it) and wipe the screen thoroughly.
Dry with another lint free cloth while the screen is still damp.

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.

Take a screen shot using Windows, sounds like a faulty monitor.

Can you post picture? From my experience, it's the moisture that gets in between the panel and not much you can do but complete disassemble of the panel to clean it out.

I think this is a dipped .33 uf or 3300pf 250v cap. I thought tantalum, but none are available at 250v, so I think it is ceramic.

http://www.badcaps.net/ has a forum and a section for computer displays. There is a recent post on a viewsonic there.

digikey.com has low cost/order shipping fees, mouser.com has parts too.

Go into control panel / sounds / sounds and audio / select audio blind / should see a driver listed in each device. Back to sounds blind /test sound, if you can see the black arrow but its greyed out then driver is faulty. If you can click on it and it changes baxk to th esquare all is OK, ensure the sound jack is plugged into the GREEN ones at rear PC. Also check in volume blind that speakers are selected.

It is the LCD itself failing, no repair for the LCD itself, the screen will need to be replaced. Likely cheaper to replace the entitr monitor
