In reality, I have been asking what is the part number of my BenQ projector. For sure, you won’t know the chip part number unless tearing the projector down to get the broken unite on hand. But in today’s post, I am sharing how to figure out which chip that assembled on your projector or projection TV.

What Is DMD Chip In Projector

Before we dive in how to find the chip for your projector, let’s talk about what is the DMD chip in the projector.

In order to make it easy to understand, I do not explain it so technical as Wikipedia did it.

In fact, a DMD is a light reflector which is in charge of reflecting light from the bulb through the lens and reach the screen.

While the image needed the black display, the DMD will reflex the light to the heatsink.

And become a black pixel appearing on the screen.

In contrast, it illuminates a bright pixel.

With millions of black and bright pixels reflected, it forms a picture as we can see.

That is to say, the DMD chip contains millions of small mirrors to project those pixels.

How Does DMD Chip Go Bad

No matter a DLP projector or TV, they are lighted up with a projector bulb which more than 100 wattages.

The bulb will produce lots of heat and need to be cooled down by a projector fan.

As time goes by, the fan will be dusty inside.

If you don’t clean the fan and the optical system, the device will be lack of cooling.

Then causes the chip to become aging quickly.

Under those circumstances, some pieces of the small mirror inside the DMD chip will be out of work.

That is the main reason that the chip goes bad.
