20 Most Recent Optiquest 17" DPT Q71-5 Monitor Questions & Answers

Boot into safe mode ...not sure what windows version you have but Google boot with safe mode with windows version windows 10, 7 XP etc You should see the bios before windows loads. If it turns black when windows is loading bad DIsplay settings or driver.

If you can get access at the back of your monitor look for the I/O board. This board is where the antenna and audio/video input are pack in.

Just check for the socket loose connection. Lock properly the connectors and resolder loose terminal connections in the I/O board

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.

One way to do it is to use the switched outlet on the back of the PC to turn on and off the monitor, but most new PC's do not have this switched outlet any more.
Another way is to use these green outlet strip, the PC is attached to the master outlet, the monitor and anything else will be pluging into the slave outlets, When the master outlet senses the current draw (sensitivity is adjustable) from the PC, the slave outlets will be turn on.

There is 2 issues here. Ether your monitor settings not set right or the display signal you are sending to your monitor is not set right.

The first thing I would do is reset the vertical & horizontal on the monitor. You would be able to to this in the menu interface of the monitor. If you are having trouble doing this let me know. I would give you a walk through but it looks like Viewsonic pulled all the CRT manuals off their site. However I do have one in my home office that I will be at in the morning that i can get the info off of for you.

Next let look at your display settings if you have Windows XP just right click on your desktop and select properties. Then go over to the settings tab. There you will see your resolutions. You will want ether 1024 x 768 or 1280 x 1024. If you have Windows Vista or Windows 7 it is a little harder to get to the option so I will work up steps and post them in a few minutes.

If you still have trouble please double check the model of monitor that you have. Also let me know if it is a standard or widescreen monitor.

Post back what you find.

More likley to have bad caps like other Optiquest monitors as shown in my albums.
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 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 your PC has changed resolution to one not compatible with your monitor. Try to boot in safe mode to change the resolution to more basic. Then reboot.

I threw it in the e-recycle bin at the recycle place and bought an Acer.
