lascapa,

First, reset the monitor to Factory Defaults and see if it fixes the issue.
* Press the Menu button on the front of the monitor
* Press plus or minus to move to Factory Reset
* Press the Menu button
* Press plus or minus to move to All Settings
* Press the Menu button

Does the issue appear in safemode?
* Click Start- Turn Off Computer- Restart
* At the blue Dell, tap F8 to bring up the Windows boot menu
* Scroll to and select Safe Mode, press the Enter key
* Select the first or only operating system, press the Enter key

If the issue appears in safemode, does the issue also appear during the monitor Self Test?
* Turn off the monitor
* Unplug the monitor video cable (either the VGA or DVI) from the back of the computer. They should never be connected at the same time to the same video card
* Turn on the monitor
* The floating dialog box should appear on-screen (against a black background). Does the dialog box float around the screen without any visual problems? If yes, the monitor is working correctly. Look to the video card driver or the video card itself as the culprit

If the monitor issue is present in safemode and the Self Test, get it replaced if still under warranty. If you have a service tag number associated with your monitor, you may use Chat or Email support to setup the monitor exchange.

If you only have an Order number associated with the monitor, you must call in (1-800-624-9896). They will need the following information -
Monitor 20 digit PPID number
Name, address, phone, email address
Order number
Issue
Troubleshooting done

lardbros,

I bought it from Ebay, so i was wondering if i got the warranty details from my seller, would I still be eligible for a replacement?
=====

Reseller (CostCo, Ebay, etc..) Monitor Warranty policy

Contact the reseller and get his Dell order number. That order number will tell us if he bought the standard monitor 3 year warranty. If he paid for the warranty, we can transfer the monitor warranty into your name. If he cannot provide a Dell order number, he most likely did not buy the warranty and bought them from us in AS IS condition. He then sold you a AS IS monitor with no warranty.

lardbros,

If he didnt pay for a 3yr warranty, then there is no standard 1yr manufacturers warranty at all?
* Correct. The resellers typically buy a pallet of our products in as is status.

So what happens to Dell customers who hae their monitor for month or 2 and it develops a fault?
* If they bought from a reseller, they must go to the reseller and fight for an exchange.

Can you tell me what causes the issue with my monitor so maybe i could fix it, or is it simply faulty?
* We do not repair them so it wold be difficult to say. A local monitor repair service could possibly diagnose it.

its yellow tape in between the backlight and lcd itself. mine had it on all four corners so i took it apart and removed the tape. refer to http://www.dellcommunity.com/supportforums/board/message?board.id=dim_monitor&message.id=64225&query.id=145591#M64225
