My hl-t6756wx-xac developed the white dot syndrome last week. It went from one dot to over 20 dots in less than a week. The samsung customer service (1-800-samsung) said my model was not covered and could not process my call to a supervisor. Ticket #5104752318 (Katie ext.12802). I have ordered the dmd board and hope this is the problem and not the dmd panel (mirrors) that some on blogs have suggested.
