Causes of DLP white death

At the heart of every DLP TV, no matter what the brand is the DMD chip invented in 1987 by Dr. Larry Hornbeck of Texas Instruments. This optical semiconductor contains an array of up to 2 million hinge-mounted microscopic mirrors, so small they measure one-fifth the width of a human hair.

The DMD chip receives the digital or graphic signal reflecting it onto the TV screen to produce the stunning images that have made these TVs a frontrunner for the consumer. The mirrors themselves are made out of aluminum and mounted on a yoke with an axle that literally twists in the middle. The DMD micro mirrors switch on and off, either tilt towards the light or away from it.

This action creates the light or dark pixels on the screen and allows for a staggering 1,204 shades of gray. At the same time, the DLP lamp generates white light that passes through a red, green, and blue color filter to the surface of the DMD chip creating millions of colors.

DLP white dot syndrome happens when one of these micro mirrors gets stuck and can no longer reflect the signal. The result is a white or black dot on the screen. As more and more mirrors become stuck, more white dots appear on screen creating an image that can’t be viewed.
