When the problems below occur after the lamp is replaced, check the following.
Maintenance
Warning:
Do not use flammable solvents (benzene, thinner, etc.) and flammable aerosols when cleaning the projector body and lens. Flammable substances
may ignite causing fire or breakdown while the lamp is illuminating.
Caution:
Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on the projector.
Cleaning of the projector and the ventilation slots
Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft cloth dampened with diluted
mild detergent, and then wipe them with a dry cloth.
To protect the surface of the projector from fading or deteriorating:
Do not spray insecticide on or inside the projector.
Do not use benzine or thinner to clean it.
Do not let rubber or plastic materials contact with projector.
Cleaning of the lens
Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens cleaning fluid. The lens surface is fragile. Use only recommended,
nonabrasive lens-cleaning materials. Do not touch the lens with your fingers.
Problem Cause and solution
