DLP projectors, are popular because they produce clear and crisp images even in the low end range.\u00a0However, there is a downside. The DMD chips are highly sensitive to heat. When the air vents and filters of the projectors are clogged up for an extended length of time, the chip will start to develop\u00a0 dead pixels due to the accumulation of dust in the vents. Meaning that the micromirrors that make up the array on the DMD chips are failing. This event is irreversible. To fix an affected projector, the DMD chip has to be replaced. This is where we come in.
