Black spots

I received my 51S715 yesterday. It looks like the (anti-)glare screen is scuffed and a Hitachi service tech should be out sometime next week to fix that. But after looking at the tv today I've seen another problem.


When I put up a 100 IRE grey field via Avia I notice tiny black spots in different areas on the screen. They look pretty similiar to stuck pixels on a LCD except that they're all either black or dark grey. Any idea what that would be?
