Fortunately, there are companies offering the offering the DLP chip for under $230.


Causes of white death

No matter what the brand, at the heart of any DLP TV 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.

As the chip receives the signal, small mirrors rotate, either tilting away or towards light to produce those stunning images that have made RPTV a favorite for viewing. Since they are mounted on a yoke with an axle that twists in the middle, these micro mirrors get stuck so they 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 un-viewable image.

    So today I called Mitsubishi about the white dots problem AND the timer issue with my TV. Same script you pay for labor they pay for part $200. Then the free bulb. After refusing that they offered to cover everything. I have to sign the documents and send them back and they will send the technician. Thanks everyone.
