Black specs on the LCD screen

Question

I have a brand new Toshiba 52HL167 Regaza, 2 days old that is showing black dots in the lower left center of the screen, i realize that some dots may be present due to the nature of the LCd technology, But these are very prominent, and almost in a perfect circle, around 3 to 4 inches wide.

What is this and can it be repaired or does the TV have to be replaced, it is under warranty.
