Although a projector screen is only a fraction of the projector’s price, it plays an important role in delivering a good clear image. But how often do we look into maintaining a projector screen? Or is there any maintenance to speak of in the first place?
The most common problems with projector screens are:
– Warping on the sides of the screen
– Fabric of the screen crumbles/ wrinkles
– Fabric turns yellowish
Things to avoid during installation:
- Air-conditioning blowing directly at the screen
This causes water vapor to condense on the surface of the screen once air-condition is switched off. Prolong exposure to water vapor will results in fungus ‘growing’ on the screen causing it to turn yellowish or even brownish
- Brackets mounted on vibrating surface
Building structures like metal beams running across the ceiling of the room might have been used to support other equipments (e.g. Air-Conditioning Unit) such equipments will cause the beam to vibrate constantly. Screens mounted on these vibrating surfaces may cause mechanism in the roller to jam easily.
- Leveling of the screen
Un-leveled screen installation will cause tension on one side of the fabric and slag on the other. Over time, such tension and slag may cause the fabric to warp or wrinkled
A screen should always be retracted when not in use. This is to reduce the amount of tension on the hanging fabric hence relieving it of the stress. Less stress on the fabric will help to prevent it from warping and wrinkling.
Not much of preventive maintenance but more like preventive measures on prolonging the life span of your projector screen.
