The projector provides 3 temperature sensor ICs, 2 sensors on the Main board and 1 sensor on the RC front board,
and 1 wind sensor on the intake duct. The sensor ICs monitor surrounding temperature of the lamp house and pan-
els/prism, and room temperature, and the wind sensor monitors airflow passed through the air filter in the intake
duct.
- Internal temperature sensor B (IC1816) (around the lamp house)
- Internal temperature sensor C (IC1814) (around the panels/prism)
- Room temperature sensor A (IC1692) (around the front cabinet)
- Wind sensor D (S901) (intake duct)

The projector is shut down and the WARNING TEMP. indica-
tor is blinking red.
When the temperature inside the projector reaches a certain level, the WARN-
ING TEMP. indicator starts blinking. If the temperature rises moreover, the
projector will be automatically shut down to protect the inside of the projector,
and the WARNING TEMP. indicator is blinking fast and the POWER indicator
turns off. When the projector has cooled down enough (to its normal operat-
ing temperature), the POWER indicator turns on and the projector can be
turned on again by pressing the ON/STAND-BY button.
✔Note:
• The WARNING TEMP. indicator continues to blink even after the tempera-
ture inside the projector returns to normal. When the projector is turned on
again, the WARNING TEMP. indicator stops blinking.
Check the items below
- Remove dust around the air filter.
- Ventilation slots of the projector are blocked. In such an event, reposition the
projector so that ventilation slots are not obstructed.
- Check if projector is used at higher temperature place (Norma; operating
temperature is 5 to 40 ºC or 41 to 104 ºF).
