TV Bug

No, not a software problem with my TV but an actual bug!

I've got a DLP TV and somehow a bug has gotten inside and is now projected onto my screen!

Yesterday I noticed an irregular black spot on the screen about an inch long. Of course the first thing I thought that someone banged into the screen and damaged it. I was giving my son the stink eye and then the spot moved! And then it flew around and landed in another section of the screen. It's been doing that all day. Lightly tapping on the screen does nothing so that makes me suspect that it is not in the screen section itself but the projection engine or lamp. I really don't want to take the TV apart, I'm sure to do more damage than good.

Anyone have this happen to them? Any suggestions? I guess I will wait it out and hope this bug dies and doesn't damage anything.....
