You were correct - they took it back and gave me a pre-paid UPS label.
The DSA815 is now with the UPS man back to Tequipment, and they said they will ship a new one out when they receive it.
At least I'm not out of pocket, though I do get to wait for another shipment California->NJ, and then NJ->California, which should take a little over two weeks. Lame.
Oh well, at least I won't have to live with the dead pixel(s).
I was going to try to deal with it, but black pixels in the menu area were quite obvious whenever I looked at the screen.
Thanks Tequipment
