just clean it off with a wipe

ViewSonic... | Answered on Jul 18, 2011


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.

Try reseating the rinbbon cable (on the LCD panel) between the LCD panel and the main board first, otherwise the worst case will be new LCD panel. You sjould also lok for any caps with domed/leaking tops.

I know this is an old post, but since it's the first Google result that shows up, here's the solution:

On the Q19wb press the '1' button, then use the arrow buttons to highlight "Audio Adjust" and press the '2' button to select. Then highlight and select "Volume" using the arrow keys and the '2' button. Then, adjust to a higher volume using the up arrow button.

Note: if you aren't getting any sould from your monitor follow similar steps above but select "Mute" and "Off" in the options.

it seems that this problem occurs because of faulty VGA card or may be your VGA adapter got damaged.if it is then replace your VGA adapter

When you get color casting on the screen (Red, Blue, or Green casting), it is either the pin on the video cable are bent or not insert properly, or broken cable inside the video cable, it can also be the video card/jack itself. You need to try this monitor with another PC first to find out where the problem is.

Hi,

Regarding your concern, just connect the audio cable from the LCD to your computer. The audio cable should also be connected to the audio port found at the back of the LCD.

I hope we fixed it. Thank you for visiting FixYa!

The usual problem with this symptom is an CCFL power supply failure. The inverter is the board that powers the backlights so you can see what is on the screen. If you look really close and with a flashlight, you may be able to see the dark shadow of the image on the screen. Without the backlight, the LCD is useless.

You can get parts from places like http://www.lcdalternatives.com/ or eBay. Search for the model number and "repair" (e.g. "Optiquest Q19wb repair") on eBay.

Open and look at the tops of the capacitors. I bet there are at least 2-3 "bulging" tops. Replace them and the problem WILL be solved;.

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

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.

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.
