Hey,
I found 1 dead pixel on mine, I believe it's a red pixel. It ends up being in the middle-lower right hand side when in "ceiling" mode. I purchased mine from the US and although I can see it if I look for it, I don't see it all the time. I decided to not take the chance in getting another unit that may have a problem somewhere else and just stick with the one I have. I haven't tried to get any service from Panasonic in Canada yet.
