							126Solving Problems
Flashing 
orangeRapid cooling is in progress. Although this is not an abnormal condition, 
projection will stop automatically if the temperature rises higher. Make 
sure there is plenty of space around the projector for ventilation, and that 
the air filter and vents are clear. If you’re using the projector above 4900 
feet (1500 m), turn on High Altitude Mode; see page 112.
Red The projector is overheating, which turns the lamp off automatically. 
Wait until the cooling fan stops, then unplug the power cord. Plug the 
power cord back in and press the 
PPower button. Make sure the room 
temperature is not above 95 °F (35 °C), and there is plenty of space 
around the projector for ventilation. If you’re using the projector above 
4900 feet (1500 m), turn on High Altitude Mode; see page 112.
The air filter or vent may be clogged. Clean them or replace the air filter 
as described on page 117.
If the projector continues to overheat after you clean the air filter, the 
problem may be caused by damage to the cooling fan or temperature 
sensor. Contact Epson for help as described on page 138.
Warning: Except as specifically explained in this User’s Guide, do not 
attempt to service this product yourself.
