Question about ViewSonic VA721 17" LCD Monitor
Our monitor would stay dim for a few minutes after turning it on. It would become bright after it "warmed up". Eventually, it would stay dim for hours and now it is always stays dim. The monitor is not only constantly dim but is getting darker and darker. It is now to the point that we can barley see any imagaes. We purchase it 18 months ago. Anybody know what the issue is and whether it is repairable? Thanks in advance!
Chances are it's not the actual CFL back-light bulbs themselves, but the back-light inverter board. If it was the bulbs you would have not had the "warm up and it get bright" issue. The board IS replaceable, (as well as the bulbs) ViewSonic charges about $36.00 USD for the board when they have them in stock. (out of stock as of yesterday 11/14/2006) It should be covered under warranty if you got longer than one year. (I know the warranty was only one year on MY VA800 but I have seen longer offered since i got mine) Good Luck I hope this helps! El Duderino

I'm no expert, but I do know thatvthis is caused by a bad backlight, which is a tiny little fluorescent tube in one edge of the moniter, it provides the light to see the image from your computer. It is repairable, but as a practical matter, for what moniters cost versus the cost of repair, usually you are better off getting a new one.

Where is the fluorescent bulb on the monitor located?

In this dell monitor it is normal for the monitor to be dim at first turn on until it gets warmed up.

It does sound like you have a bad backlight. This monitor has a 3 year warranty on the backlight, if you are the original purchaser, contact viewsonic for repairs. If you are not the original purchaser, you can repair it yourself for less than $50 by replacing the backlights.
