White Dots on Projector Image Repair
Projectors equipped with digital micro-mirror device will fail after a period of use. The length of time depends on the environment where the projector is being used. The hotter the environment, the earlier the projector will fail. When it starts to fail, you may notice snowy dots or stars on projected images. Once this anomaly starts, it is irreversible. Images will gradually degrade until the whole screen gets covered with dots.
We can now repair this fault and give your projector a new life again. All repairs are with standard 3 months warranty but once repaired, the machine is guaranteed to work as new for up to 3 to 4 years, depending on the environment
This is a complex job, not for a DIY enthusiast.
Advantages and Disadvantages to DLP Projectors
DLP projectors require less maintenance than LCD projectors because they have a filter-free and sealed chip design, which means dust can’t settle on the chip and cause an image spot. They are effectively immune to color decay. Furthermore, they are not subject to the misalignment that can occur in LCD projectors with a three-panel design, which require each panel to be in perfect position to combine the image at the proper angle.
DLP projectors are not readily compatible with zoom lenses or lens shift functions, This result in poor viewing range. As such they are best suited to smaller environments.
