Are you sure it is a dead pixel? A single dead pixel would be rather difficult to spot on most cameras. Also, if it is a dead pixel, it would likely have been there from the start. I'm not saying impossible, but if this developed over time, then it probably isn't a dead pixel.

Quite possibly it is a speck of dust on the sensor. This is a frequent problem with interchangeable-lens digital cameras. It is possible to clean it yourself if you have the correct tools, or most camera shops could likely take care of it for you (for a fee of course). Warning: DON'T try to touch the sensor with a Q-tip, Kleenex, or your fingers. Don't try to blow on it with your mouth. You WILL make the problem worse.

There is a post on cleaning here:

You can also readily find more information if you search on the Internet.

I'm glad to see people referring to that article.

+1 on making sure of what it is before proceeding. A pixel map will knock out any pixel problems (usually in the setup menu of the camera) and it won't hurt to run it. The only time I've ever had a problem was with a hot pixel (I guess it could also be considered to be dead) and it showed up Red. I've also seen them show up Green. If it is Black however and remains after the pixel map, chances are pretty fair, it's dirt.
