Maintenance
■ Protection Against Overheating
Your projector is provided with internal protection circuits for preventing fire and damage to
internal components due to abnormal temperature.
When the power indicator LED is blinking:
● Action
1. Unplug the power plug from the power outlet.
2. Check the air filter for dirt.
* If the LAMP LED also is blinking at the same time, replace the lamp.
For details of how to replace the lamp, see page 46.
When the ALARM LED is lit:
● Action
1. Unplug the power plug from the power outlet.
2. Check the following and take corrective actions.
Use your projector within an ambient temperature of
0°C to 35°C (32°F to 95°F).
Is the ambient temperature
more than 35°C (95°F)?
Are any vent holes blocked?
Is the air filter clogged?
A probable cause is an
internal circuit problem.
* When the ALARM LED is OFF, your projector is working properly.
Ask your dealer for repair.
Clean the air filter.
See "Cleaning and Replacing the Air Filter" on page 48.
Place your projector away from walls and other objects.
See "Do not block the air vents" on page 4.
