20 Most Recent ViewSonic Optiquest Q19wb LCD Monitor - Page 3 Questions & Answers


First, we need to find out if the problem is in the monitor amplifier or in the PC sound card.
Try feeding the monitor with MP3 player first, if you do not get sound, then you need to open up the monitor and find out if the amplifier is getting the 12vdc feeding it. It will not be worth to have the monitor repaired by the shop because the amount of money for repair will be better off with new powered speakers system tahe will give so much better sound than the built-in speakers in your monitor.

Look at the board where the AC power connector comes in that is the power supply board, there are more than one versions so it nay not have the same caps value.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 Viewsonic/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.

You need to download the driver from DELL for your video card, my 3000 use video driver R79733.EXE.
You may have virus in your computer if you cannot update the drivers, sometime it is better to start from clean drive to help get rid of stuff that get installed into the computer.

You are going to have to open it up, the first place to check will be the power supply section for bad caps (bulging/leaking). Post back what you see so we can guide you further. See example of failed VIEWSONIC monitors here for a guide:

sgcb1971, There are lots of pics on web for you to view and then you will know what to look for. Electrolytic filter capacitors are not to hard to spot on a "switch-mode-power-supply"/"ccfl inverter supply" combo board. Why don't you visit YOUTUBE for some video clips of "lcd monitor disassembly" and "lcd monitor repair" . Also try www.ccl-la.com/badcaps.htm for more clues as to just what to look for. Ya know , you need a soldering iron to replace them if they are bad!!! It's not like changing batteries in a flashlight 12fixlouie

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

You can take the unit apart, in there you will see the power supply, check the fuses(small) and check the caps to see if the tops are bluging...

ViewSonic... | Answered on Feb 25, 2010


You can have the a LCD controller (circuit board on the LCD panel where the flat connector from the digital/controller board is connected to) failure or the falt connector came loose. Check that out first.

This happened to me as well, and after looking around, it looks like its a common problem with these monitors. I was able to fix it by replacing a capacitor on the power board. It was the 1000uF 25v one that went bad for me. $1.79 @ Radio Shack. Granted there are 6 or 7 capacitors in there, so your milage may vary a bit.

Look in the power supply section first for bad caps, then report back what you see so we can guide you further. Bad inverter or bad lamps can also give you the same symptom, see example of failed monitors and bad caps here: http://s807.photobucket.com/home/budm/allalbums

Hi,
It's probably a setting on the monitor itself. Try pushing the menu buttons on the monitor, and see if there is an automatic image adjust. Or, just try turning the monitor off and on - it might readjust itself when turned on.
Please rate my response!!!

Ahh sounds like monitor requires repair at specialist......get a quote first.

it might be set to a different output setting, try to set it to LCD.

I would check the power cable is inserted fully, then check PC to monitor cable is also inserted firmly.

If still same try monitor on another PC as it may be a video fault from PC.If it works OK on another PC then video card / mobo is faulty.
If your PC has a video card shut down PC pull power plug out of PC and remove replace video card, quite often fixes that problem.
