[ ]Samsung HL56A650C1FXZA 56-inch DLP TV DLP Chip Replacement
Introduction
The DLP chip in your Samsung television is a very fine piece of technology. Texas Instruments describes it as such: [ … ] "A DLP chip's micromirrors tilt either toward the light source in a DLP projection system (ON) or away from it (OFF). This creates a light or dark pixel on the projection surface. [ … ] The bit-streamed image code entering the semiconductor directs each mirror to switch on and off up to ten thousand times per second. When a mirror is switched on more frequently than off, it reflects a light gray pixel; a mirror that's switched off more frequently reflects a darker gray pixel. [ … ] In this way, the mirrors in a DLP projection system can reflect pixels in up to 1,024 shades of gray to convert the video or graphic signal entering the DLP chip into a highly detailed grayscale image." [ … ] When your chip begins to fail (from age or excess heat) these microscopic mirrors stick either on, or off. This can lead to spots on your TV, either white ones (for those mirrors stuck in the on position) or black ones (where the mirror is stuck off). [ … ] Usually this begins with one mirror. You'll notice a white or black pixel glaring at you while watching your favorite high-def movie. Slowly, as the chips continues to fail, the spots will spread across the TV until your movies and television are almost un-watchable. [ … ] The great thing about owning a DLP television is that many of these parts are readily replaceable. The DLP chip is one of those items. Learn how with this guide! [ … ] Note that the Samsung TV uses the same Texas Instruments across a number of models, and with some Mitsubishi and Toshiba DLP televisions. Make sure the chip your are buying matches the model number of your TV.
