Routine maintenance:
1/ Mechanical aspect
Strictly prevent strong collisions, squeezes and vibrations. Because the strong shock can cause the

displacement of the liquid crystal, affecting the convergence of the three LCDs during the projection,

the phenomenon of RGB color not coinciding occurs, and the lens in the optical system, the mirror will

also produce deformation or damage, affecting the image projection effect, and the zoom lens will

damage the track under the impact, causing the lens to freeze, and even the lens rupture cannot be used.
2/ Optical systems
Pay attention to the use of environmental dust and ventilation heat dissipation.
3/ Lamp source section
Most intelligent projectors use LED bulbs, LED need to be due to the narrowness of a single luminous

surface, usually large-scale integration on the circuit board, the formation of a relatively large light source,

which will cause a lot of heat accumulation, sometimes break through the circuit board. Therefore,

the heat dissipation of LED lights must be good. In addition, reducing the number of switches on

and off is beneficial to the life of the bulb.
