My Optiquest Q7 monitor is 3yrs old. When I power up my CPU the monitor stays dark with a 1 second clicking sound but the monitor eventually lights up. the dark ness is getting longer. this has happened on 5 or 6 sucessive power ups. Can it be fixed or should it be replaced?

More likely to be bad caps in the power supply, look inside and report what you see so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Please help me my optiquest q19wb model #vs11443 is shuting off aftre 1 second i opened it and no capacier were damadged what is wrong... the unit is not old 2 years i am not rich and want to save...


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.

No sound


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.

No picture on 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.

Sounds like the LCD panel inverter is going out, if not gone out completely.

Monitor flashes on then goes black.


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.
