Well, this thing was already discussed in HW10 thread and as far as I understood its common thing for LCOS PJs - Sony and JVC.
It's annoyingly visible during start-up. Mine has top left and lower right corners too bright. After 5-10 minutes bright corners became much less visible, but during dark scenes or 2:35 format movies top left corner still little brighter.
After week of owning I've returned to dealer's store with my PJ and checked 2 more HW10s. One had all four bright corners at start up and slightly worse color uniformity than mine (mine is very good - tested thoroughly). Second had two bright corners but opposite to mine top right and low left.
At that time I still had mine Panasonic PT-AE2000 with good color uniformity, but "infected" with dust blobs that I had to blow out again and again.
So I've decided to keep HW10 and sold my AE2000. That's it.:-)
