    I just notice glaring at the screen that there is image coming but very very dim. Also, resolution looks like 640x480.
    I also did not have the driver for this monitor installed. i am using windows 2000. Any suggestion would be much appreciated.
    I did download the driver from site but it is in zip format , now i am trying to download unzip software.

If you can see the screen faintly still the backlight is dead. If the inverter of inverter fuse was dead there would be nothing at all on the screen period.

If you have the pc on and the monitor light stays green, take a flashlight to the screen. If you can see the images while shining the flashlight into the screen, they will be hard to see but they will be viewable, then its most likely the back light. The vx900 takes 4 bulbs and they are about $12 US each. Anyone who knows how to solder should be able to replace them.

My symptoms were exactly the same as what Fuzzytek described and not wanting to hassle with soldering issues, I went looking for a replacement inverter board. Lo and behold, I found They seem to have inverters for most monitors, I don't know how reasonable the price is, but it was good enough for me....about $95 with shipping. Ordered it Sunday night, it arrived today (Wednesday) even with the cheap shipping, and it took me about 1/2 hour to get everything reassembled, checked out and running. They even have how to documents with pictures to walk you through the process. That alone is valuable...I think the cases on these things were designed by the Ex-wives association to torment us. They also have the replacement CCFL bulbs in case that is the problem.
