Question about ViewSonic Optiquest Q19wb LCD Monitor

1 Answer

How do I open the monitor case on my Optiquest Q19wb I have the problem of the screen shutting down after a few seconds. I can turn it off and then back on and I get a few seconds of life again. It was abused by an Ex-Wife and I think she shook something loose or it just needs the capacitors changed like I have read about others with the same problem.

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.

Optiquest is the Viewsonic low end products. You can take it apart and look inside.

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
