Audio-visual systems are like most other high-maintenance electronic solutions. If you work with the equipment regularly, you may start to notice the effects of dust (especially in Arizona), changes in the optical features and other problems. This general wear and tear is normal, but with a little maintenance, you can help to maintain its normal lifecycle and protect your investment.
If you’re experiencing some wear and tear with your audio-visual systems from CCS Presentation Systems, then it might be time for our CCS Factory Authorized Service Centers to take a look. The CCS audio visual services group can diagnose problems and show users how to take care of the equipment. The team provides a fast turn-around on all your audio visual repairs, as well.
If you’re using a visual projector in your place of business, it’s important to keep your projector free from harmful dust elements, and making sure to turn off the light on the projector after use. We’ll describe the effects of dust below. But in the case of the light, your projector’s lamp deteriorates the optical coatings that ultimately create the colors in your projected image. So if the light is left on and burning the optical coatings, you might find your audio-visual presentation is less than you’d prefer. Additionally, dust in the light path has a direct effect on the image color, as well as the indirect effect of retaining heat against the LCD’s and polarizers, thereby shortening their life.
Here’s how you can spot if dust is becoming a problem: a dirty projector first shows itself as a magenta colored cloudiness in what should be a white background. If your lens has enough focal range, you can shift the focus away from the front of the prism (your projected image) back to the surface of the LCDs.
The actual particles of dust can then be seen, and their location can be determined by their color. Magenta specs are contamination on the green LCD, yellow ones are on the blue LCD, and blue ones are on the red LCD. The magenta color shows most to the human eye due to our eyes being most sensitive to green light.
Effective cleaning of these surfaces cannot be done without opening the projector, and should not be done by persons who are not trained to handle them, as they are easily damaged.
The CCS Service Department can help you protect your investment. It’s important to do so. Service contracts and preventative maintenance agreements can extend the life of installed equipment and can provide onsite response to ensure peak performance.
