Sony HD 3D Video Projector – Sony VPL-HW40ES – How to replace the lamp – How to clean the air filter – How to clean the lens – Projector repair and service

Cleaning the lens

The lens surface is especially treated to reduce reflection of light. As incorrect maintenance may impair the performance of the projector, take care with respect to the following:
# Wipe the lens gently with a soft cloth such as a cleaning cloth or glass cleaning cloth.
# Stubborn stains may be removed with a soft cloth such as a cleaning cloth or glass cleaning cloth lightly dampened with water.
# Never use solvent such as alcohol, benzene or thinner, or acid, alkaline or abrasive detergent, or chemical cleaning cloth, as they will damage the lens surface.
Cleaning the cabinet
# To remove dust from the cabinet, wipe gently with a soft cloth. If dust is persistent, wipe with a soft cloth slightly moistened with a diluted mild detergent solution.
# Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, benzene, thinner or insecticide.
# Using such materials or maintaining prolonged contact with rubber or vinyl materials may result in damage to the screen surface and cabinet material.
Replacing the Lamp and the Air Filter and Cleaning
1. Turn off the projector and unplug the AC power cord.
2. When setting the projector on a flat surface such as a desk etc.,
put a cloth to prevent the surface from being scratched. Reverse the projector as illustrated, then place it on the cloth.

Be careful not to touch the optical block inside the unit.
6. Close the lamp cover, then tighten the screws.
7. Remove the filter holder.

9. Attach the new air filter so that it fits into each claws (10 positions) on the filter holder.
Attach the air filter aligning it with the shape of the filter holder. Also, do not touch the fan after removing the air filter that is set deep inside the projector.
10. Attach the filter holder.
The projector will not turn on unless the filter holder is securely closed.
