THE PROBLEM: An orange LED indicator lit up on my Mitsubishi DLP TV above the lamp icon. Not knowing what it meant, but having a bad feeling about it, I consulted the manual, which said that the indicator was a lamp end-of-life indicator and that I would need to replace the halogen lamp which provides the projection lighting for my TV. Wanting to do it myself and save the service cost, I ordered a replacement halogen lamp.

The DMD chip is probably the world's most sophisticated light switch. It contains a rectangular array of up to 1.3 million hinge-mounted microscopic mirrors; each of these micromirrors measures less than one-fifth the width of a human hair, and corresponds to one pixel in a projected image. g+
When viewed from directly in front DLP televisions have excellent picture quality that rival any of the other modern TV technologies. Like plasma there is no worry about motion blur and like LCD/LED televisions there is no worry about burn-in from having a static image on the screen for extended periods. While burn-in has been virtually eliminated from plasmas it can still happen if static images are displayed for extremely long periods of time. g+
