*When the TEMP LED is OFF, your projector is working properly.
*Replace the lamp at the same time when the LAMP/COVER LED is on. For details on how to replace the lamp, see page
*A blinking TEMP LED is a warning that the temperature is too high. If the operating environment improves within 10 seconds after the LED starts blinking, the warning will stop. (When the TEMP LED goes out, normal operation continues.)
If the TEMP LED blinks for more than 10 seconds and the operating status does not change, the LED stops blinking and stays on and the lamp turns off.
