Question about Optiquest 17" DPT Q71-5 Monitor

Open Question

I left my Optiquest Q7 monitor running and went for lunch for an hour and then when i came back the screen is black. The green light is on but nothing is happening. I disconnected it, then tried it on another computer and it still doesnt work. What could be the problem? This monitor is about 3 years old.

SOURCE: 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.

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.

SOURCE: 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.

SOURCE: 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.

Optiquest q20wb LCD has black screen & green power light flashing


Hi Rickyknows2,
If you are not hearing any beep I assume you are having problem with your video so, please ...
- open your PC and check whether your video card is well placed (sometimes it looks fine but you never know) remove it and put it back.
- If you used to remove often the cable from the PC, it might be that the pins from the monitor cable are even broke... please check.
- try to find another video card and replace it just to make sure its the video ...
- last... reset the bios (but I doubt that this is your problem)
chsers ..

How to open case of Optiquest Q7


Almost all LCD monitors use kind of the same enclosure. On the back or on the bottom there may be two screws. If so, remove them. If not, no worries. On the bottom you should find a couple of indentations in the plastic where the front and back join. I like to use a Radio Shack fiberglass flat bladed diddle stick. Put this into the indentation and push up. This should release the bottom. Now the trick. Use this diddle stick (it must be flat bladed) on the front. Using only your fingers gently lift the plastic case on the front away from the screen. You should see the metal case of the screen. Begining at the local right or left put the diddle stick between the metal only part of the screen and the plastic front. Reminder. This stick must be between the metal screen enclosure and the plastic front only. Once in this position, you can slide the stick upwards along the metal case. As you do the plastic case will pop away from the rear case. Provided there are no screws you missed. Now do the same on the other side and then the top. You should now have separated the front case from the rear case. Next take apart the metal shielding (usually screwed together). There may be metal tape placed in strategic places, make sure you gently unloosen this tape and reapply when you're finished. Hope you know what you're doing from here!

Is there any way to remove the base from the Optiquest Q7 monitor? We would like to attach the monitor directly to the server rack.


On mine I pulled on the round cover where the base attaches to the screen. It came off and there are 4 screws underneath. Remove those screws that hold on the base
