This happened to me and I was able to fix it. I cracked it opened and found a bad capacitor, bought a replacement at Radio Shack and I'm back in business. Actually using it right now to post this.

Check the directx if it's up-to-date or not. It might be the reason why you are having this issue. Or it could be that there is a driver that you need to update. To make sure that it's not a driver problem, I suggest that you scan your computer with RadarSync. It's a PC driver updater.

I had this problem with my Q9 and I was glad to find the FixYa website with help. But I will offer more detailed info for novices to make sure you find the capacitors. First of all, it is not easy trying to find out how to open the monitor up! First, set it down flat on it's face, being careful not to scratch the screen. Pop off the cap that covers the stand mount to the screen. You might also want to remove the base by squeezing the bottom tabs to the middle and pushing them out. Once the base cover is removed, you will see the 6 screws holding the base arm to the screen. Remove those and the arm will come off. Now, on the bottom right, there is a beveled slot where you can fit a flat bladded screw driver to start to snap open the case. Move around the case separating it carefully until it is completely un-snapped. Unplug the speaker cable (mine gave me some trouble but I worked it side to side and it finally let go). You can push the videop cable through the the back case to get the case out of the way. Once you have removed the back half of the case you will not immediately see the offending capacitors. You will need to remove 4 phillips screws holding down a metal shield on the power board. You may also have to remove some metal tape covering 2 of the screws. When the screws and tape are removed, you will need to slide the metal shield to the right to release it from a 3 pin connector that the two boards. Be careful that you don't damage that connector. Lift up on it a little and slide it left until the connector is disconnected. Now you can see the capacitors. I only had to replace the 3 bulging ones and that fixed my problem as well. Thanks all for your helpful comments in saving me money on a new monitor!!

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

Hello,

This type of problem is usually caused by a failure of the power supply board. The power supply puts out 5v and 12v to the electronics. If the power supply 5v side fails then the electronics does not get the right power but the back lights do so you get a white screen and no picture. The audio electronics are powered by a different power output. Here is a link to a repair guide for the Q19w that shows how to dis-assemble the unit and then which capacitors need to be replaced to revive the unit.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Hello,

This is usually caused by a failure of the power supply board because of capacitor failure. The board is easily repairable if you can do a little soldering. Here is a a link to a page that shows how to open the monitor, remove the power supply board and what needs to be replaced to repair the unit.
