Dark speck on rear projection sony

[weren]

Hello I have owned my Sony 57WS510 for about 6 months now with no problems. This morning I turn the TV on and notice a dark speck in the center of the screen which looks like it is behind the inside glass. Can anyone tell me what this could be or why this happened? Can it be a burn mark or what i am hoping is just dust that got in on the inside of the glass. This is very visable and would make watching this TV very annoying from now on. PS. Never have used video games just normal TV on this set. Thank you for you help.

It is probably:
a) dirt, dust, insect (dead) on the back of the screen
b).... on a lens
c) .... on the mirror
