I have a fairly new Optiquest Q7 monitor...the light is green but no picture shows up...When I connect a different monitor it works fine. Is there not a reset function for this type of monitor?

The Q7 has a tendency to burn up transistors and a high voltage capacitor on the one half of the inverter board which is part of the power board.
I have repaired 1/2 dozen of these with that problem.
Only way to tell for sure would be to open it up and look at it.
If you can do that and send me a picture to bammbamm@ptd.net, I may be able to confirm this.
The other possible problem could be a bad bulb, but since it is fairly new ? that is probably not the issue.

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.

It's an issue with the power supply, most likely the Capacitors (one or more) may be shot. Open it up if it is out of warrenty, look at the capacitors (they look like cans), if they are bulging at the top or even sides they are bad. This is a common problem with this monitor. Crappy Caps used in manufacturing. Replace all the caps with same rated caps and you should be good. Do your research on how to desolder the old ones off and proper installation of the new ones.
