SERVICE MANUAL

6 REPLACEMENT OF MODULE LEVEL ELEMENTS

The following procedures must only be carried out by qualified and experienced service
personnel authorized by means of the Module Level Service Agreement to perform module
level repairs on LCD projector units.

Always remember to test the product thoroughly immediately after service.

6.1 SAFETY GUIDELINES

The following safety guidelines should be followed at all times. Failure to do so could seriously damage the
projector unit, or create a hazard to the service personnel or projector unit owner, and may violate warranties
on the product.

This product operates on mains voltage. Make sure to unplug the power cord before
attempting to open the unit. To avoid burns, do not open the unit to replace parts until it has
cooled down completely after use. The interior of the projector becomes hot during operation.

Do not under any circumstances operate the lamp whilst the housing is open, as there is a risk
of permanent injury due to contact with high voltage elements, explosion of the glass lamp
bulb or exposure to high levels of UV radiation.

The UHP-lamp used is high voltage when starting and high-pressure when operating.

6.2 PROTECTIVE CLOTHING

The following protective clothing should be worn in addition to normal work clothing when servicing the unit:

• Static free cotton gloves

• Full face visor (for all replacements of illumination/optical module level elements)

6.3 TOOLS

The work should be performed at a static-free workstation. Work in a dust-free environment if possible and
have access to a high-pressure air blower to remove dust when assembling the unit.

The following tools are required to service the LCD projector unit:

ID TOOL USED FOR

1 Torx no. 10 screwdriver Replacing elements
