Black Dots Appearing On Screen
Black dots started appearing in strips across the screen. The image is visible but little by little the black dots are becoming bigger and bigger. The 2 cooling fans are working properly so no apparent overheating.

If the dots are always there even with HD HDMI signals and menu OSD, then the DLP chip is failing. This is a lengthy process to change, and some people opt for a complete optical engine to get the new color wheel and light tunnel. If you have a technician do the chip, ensure that he purchases the IC from Mitsubishi since they have the best price (around $160) plus labor $250-$300.
