Led Light Engine What Are The Spots On My DLP Picture?

What are the spots on my DLP Picture? - led light engine

I bought a brand new Samsung LED DLP again with the engine. Out of the box I have these spots on my picture, regardless of source you choose. They are dark gray. For points, I think in a strange and dark, to think that there are some that are more squiqqley. The points are not on the TV screen are in the picture. Has anyone heard of the mirrors are dirty and design something similar to what I got? The picture still comes through fine, just a few places in some places. I have the Samsung TV service every time I remember, but I'm harmful, if my hypothesis could be correct on the mirrors.
