higher. Make sure there is plenty of space around and under the

projector for ventilation, and that the vents are clear.

The air filter may be clogged. Clean or replace the air filter.

temperature range of the projector and there is plenty of space

around and under the projector for ventilation.

meters), turn on High Altitude Mode in the Operation menu

Flashing red There is a problem with the fan or temperature sensor. Stop using

the projector, disconnect the power cord, and contact Epson.

Flashing red The lamp may be burnt out. First make sure the lamp cover is

securely installed. If that’s not the problem, the air filter may be

clogged. Clean or replace the air filter.

If this does not resolve the problem, let the lamp cool and then

remove it. If the lamp is cracked, replace it.

If the lamp is not cracked, reinstall it. If reinstalling doesn’t

work, replace the lamp.

If you’re using the projector above an altitude of 4,900 feet (1,500

meters), turn on High Altitude Mode in the Operation menu

If none of these suggestions resolves the problem, contact Epson.
