42 inch DLP was also making a loud whinning sound which would gradually fade out over 5 to 10 minutes. Had it serviced Oct 2009. Told dust had clogged fan. Was cleaned out and was told sound would soon stop. Never did. Just had serviced by another technician, who immediately diagnosed it as the light engine. Part was ordered, but it's taking 3 weeks for the repair. In the meantime the light engine has completely failed-no picture. Fortunately extened warranty was purchased so repair is covered. Oh yeah! Its on the 2nd lamp. Hope to be able to get another before Oct when the warranty expires. Good luck with your problem.

id the sound is to loud i think its the Color Wheel maybe its broken or louse you need to check and see that you color wheel is not making the loud sound!
Good Luck on fixing your TV
Is it a clicking noise or a loud humming noise?
If it is a clicking noise I would open the set and check for something in the way. if nothing is in the way I would remove the fan and try spinning it by a finger. If it seems like it isn't spinning right, I woule buy a new fan.
If the fan makes a humming noise try to clean it out well. It should fix the problem with the noise.
Big TV's seem to **** in alot of dust. I am sure the fan is just clogged..
