Question about Optiquest Q 71 17" CRT Monitor
On most lcd monitors the cost of the screen is usually close to the cost of the whole monitor, my feeling is if your monitor is under warranty then they will send you another monitor. If not then your going to need to search on Ebay, Google etc to see if you can find a damaged monitor with a good screen and have it cost less then the cost of a new one.

Is there a rca/headphone jack for the monitor? Make sure that the jack is plugged into the computer's audio out rca jack. A driver should not be needed for the audio on the monitor. If the jack is plugged in make sure that the audio is not muted on the computer. Right click on the speaker icon in the right bottom of the screen on the windows tray nand open the sound mixer. Make sure all the sounds are on. Then check the monitor settings and make sure the sound is on and not muted thru the monitor buttons. If the cable is good and all these things are ok then the internal sound amp in the monitor might be bad.

Check the VGA cable connections at both ends, also try the monitor on other PC to so you will know for sure if it is the monitor or the PC Video card problems.

More likley to have bad caps like other Optiquest monitors as shown in my albums. Basic LCD monitor troubleshooting guide:
If you are going to DIY 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/home/budm/allalbums
