Happily using system and suddenly display just fades out quickly to complete black, then starts pulsing every 3 seconds - a very quick slight white flash over screen accompanied by green flashing on/off button on front of display - every 3 seconds.
Cannot turn off - pulsing just keeps going until pulling the plug. Have tried monitor on different computer, same problem.
No picture, just pulsing.
Monitor is not quite 2 years old.
My name is Todd and I'm a customer advocate at Dell's corporate headquarters. My team helps customers via blogs, forums, and other tech sites online.
You said the monitor is 2 years old. Do you have the original order number still? Depending on how you purchased the monitor it may have up to a 3 year manufacturer warranty and I may be able to replace it if it is within that warranty period.
Please email me at [email protected] if you can locate the order number and I'll be glad to see if its still under the manufacturer warranty. Include my first name (Todd) in the subject line of the email so it can quickly be routed through to me, and include the order or customer number if you have it.

You should be able to remove the LCD hingecover and reeseat the video cable. But hte issue may be a damaged cable going thru the hinge assembly which would require a replacement LCD.http://support.dell.com/support/edocs/systems/vos1500/en/sm/display.htm#wp1179838
You can check the brightness with AC in the BIOS and match it with running in battery or else, when you plug the ac adapter, the lcd goes dim, press and hold the FN buttong and tap the up arrow then reboot and try to see if it will still do it. But still the best way to do it is going to the BIOS by pressing F2 at the Dell logo startup.
I had this problem! It was the Cars Battery. Kenwoods unit's fade or go completely blank when there is little power to power the stereo. Try charging your battery or grabing a new one from a scrappy! I was all over the net looking for help but finally sorted it!
P.S. My younger brother had to do the exact thing and it worked for him as well!!!
It sounds like the backlight in he LCD display has gone bad in the phone. Most displays now have an integrated backlight, so the entire display will need to be replaced. Its not considered to be a user replaceable component. Unfortunately, you'll have to take it to be repaired. The fact that you said it was "fading" before it completely went black tells me that it was going bad and about to fail.
