intel iMac 24" smudge/grey/dark spots and area BEHIND the LCD...

Got a BTO 24" iMac in July 08, which is running reasonably well. A few months back I noticed what I first thoughts was dust spots on my dSLR sensor showing on the iMac screen, the realized it was on the screen itself, thought it was from the desktop (Earthdesk) burn-ins or similar. Now after carefully viewing the screen it seems to be smudge or burn in marks BEHIND the LCD but in front of the back light. It is located in the middle top part of the screen, slightly darker covering a irregular areas, but rather large stretching over 2 areas approx. 2x4 inches each. Not changing with heat, but is persistent, always there. The iMac is not running very hot at all normally, this was the reason for the BTO and not taking the standard 3.06 GHz. In comparison the 2.8 runs with almost 50% less heat. Tried to take pictures of the spots, but the screen+sensor creates a terrible moiré pattern, will try again with my other camera.
* Has anyone seen this and have any tips how to deal with it?
* What is the best way to test the screen in osX (yes, I am a switcher...)?
* Can I attach pictures to posts in this forum?

Spoke to Apple today regarding a very similar situation with the screen. I have change the screen every 2 months since August 2009, because of screen burn in or some other issue with the screen.
Just spoke to them today, they are saying it is an environmental issue where the machine is being used and as such they are not willing to replace the screen, given the history of my machine’s screen replacement.
This is what they replied, “the dark patches may be environmental but its impossible that this customer is the only one to get panels with this defect consistently.”
This is Apple saying this is not their problem anymore and they are not going to honour the warranty.
