Question about ViewSonic Optiquest Q19wb LCD Monitor

1 Answer

I recently obtained a optiquest Q19wb monitor to add as an extra screen to my laptop. When I plug it in the picture is all green and does not use the whole screen. I tried to decrease the green value but with it all the way down it remained quite green. I tried reseting the monitor but that did not help. What else is to be done?

When you get color casting on the screen (Red, Blue, or Green casting), it is either the pin on the video cable are bent or not insert properly, or broken cable inside the video cable, it can also be the video card/jack itself. You need to try this monitor with another PC first to find out where the problem is.

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.

Viewsonic Optiquest Q19wb lcd Monitor goes blank after 2 secs. A couple of posts say replace the 1000uf 16v Cap My problem is i can't find them on the pcb (where are they?)


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.

Q19wb Monitor Replacement Part Numbers Needed


Look on eBay for "Optiquest Q19wb repair" or "Optiquest Q19wb power"

This is a common failure mode. You can either buy a set of capacitors and solder them in, or buy a replacement power supply board if you cannot solder.

One eBay seller notes the power board as an ILPI-025, which is common among the following models:

Power Board ILPI-025 For LG W1934S & Viewsonic VG1930WM & Optiquest Q19WB & Acer AL1916W Ab etc
Model:ILPI-025 REV:E 79069140

Just let Windows install IE 8 and now the desktop picture is over


Change the resolution. Right click in the middle of the screen over nothing, and select properties then select the settings tab and move the slider left for larger resolution.
