SERVICE MANUAL CP-X325W
Caution
Be sure to read this manual before servicing. To assure safety from fire, electric shock, injury, harmful radiation
and materials, various measures are provided in this Hitachi liquid crystal projector. Be sure to read cautionary
items described in the manual to maintain safety before servicing.
Service Warning
1. When replace the lamp, to avoid burns to your fingers. The lamp becomes too hot.
2. Never touch the lamp bulb with a finger or anything else. Never drop it or give it a shock. They may cause
bursting of the bulb.
3. This projector is provided with a high voltage circuit for the lamp. Do not touch the electric parts of power unit
(main), when turn on the projector.
4. Do not touch the exhaust fan, during operation.
5. The LCD module ass'y is likely to be damaged. If replacing to the LCD module ass'y, do not hold the FPC of
the LCD module ass'y.
