I just recently bought a Mitsubishi HC3 LCD projector and have been mostly happy with it, but there is a blue spot on the bottom of the screen. I am assuming that it is a dead pixel, but I have a question for someone out there. With a dead (or always on blue) pixel, will the surrounding pixels be perfectly normal, or will they have some degree of blue discoloration as well? Could a dust blob look like a discreet blue pixel with some surrounding haze? This changes whether or not I can exchange the projector. Otherwise, I am happy with the projector, especially for the price. Thanks in advance for the info.
