Viewsonic q20wb monitor flashing green light

This has happened on several occasions:
If the power goes out-always does it.
If i restart my computer before i turn the monitor off.

My monitor will not come back on, the green light will flash.
In the past i have been able to get it to come on by unpluging the monitor and rebooting the computer. But this is not working anymore.

Monitor is out of warranty.

Thanks for your help

    The problem is the monitor. I have the same problem when rebooting. You need to turn your monitor off during reboot. After your computer is completely rebooted, you can turn your monitor back on and the green light will stop flashing. There is a flaw in the MONITOR!!! When new this did not happen!

    With mine the green light just flashes constantly when I turn it on. The only way to turn it off is to unplug the power entirely. I have no idea why. It worked fine and then I rebooted and now I can't even get it to shut off.

SOURCE: Monitor flashes image for split second then goes blank but green LED flashes as well

while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.

Occasionally this will not work for me, but if I repeat it it normally works

Hope this helps - my problem is intermitant so it may be different to what u guys have

Sounds like that monitor has reached the end of the road. I would recommend purchasing another monitor, other than view sonic. Purchase a Dell..they are great!

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 ..

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.

Q20wb wont turn on or off and it just sits on black screen with dim orange light showing. solution?


That is a typical "standby" mode that most monitors go to when the computer has been powered down. It is using about the same amount of power as a monitor that is plugged-in to AC, but powered off. I wouldn't worry about it.

Optiquest q20wb Screen goes blank after powering on


I'd like to report a success story. I had this same problem with my Q20WB. It sat for over a year in my garage. I eventually bought replacement capacitors, soldered them in, and now it works. You can find kits with the right capacitors preselected, or if you feel like it you can also buy them individually.

good luck

Optiquest q20wb Screen goes blank after powering off


I had the exact same problem. The screen went black and the green light flashed. I went ahead and took the monitor apart (scary) and took a look at the power supply circuitry. I saw 6 suspicious electrolytic caps on the board. Three 470uF 25V 105 degree C caps, two 1000uF 10V 105 degree C caps, and one 470uF 10V 105 degree cap. They all appeared to be slightly bulging and one even had a small hole in the top. I decided to replace all of them. The parts cost a little more than 5 bucks. I couldn't find a 470uF 10V cap at my local store so I bought a 16 V version instead, which is fine. Anyway, after replacing all 6 caps, the monitor works as good as new.
