Can anyone help. Have sent py pj back to panasonic as have seen what I thought were dead pixels, 4 green and 1 blue. Only really visible on grey background screen. Engineer phoned me to say they were not dead pixels but illuminated pixels? said that they were not visible on a white screen and something about intensity degree's and percentages thereof. Outside of Panasonics tolerances so have to lump it. Anyway, if anyone could give me their definition of dead pixels I would be very grateful.
