The projector is overheating, which turns the lamp off automatically. Wait until
the projector switches to standby mode (about 5 minutes). Make sure there is
plenty of space around and under the projector for ventilation.
The air filter may be clogged. Clean or replace the air filter as described on
pages 80 to 82.
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 (see page 71).

the projector, disconnect the power cord, and contact Epson for help as

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 as described on pages 80 to 82.
If this does not resolve the problem, let the lamp cool and then remove it. If the
lamp is cracked, replace it as described on page 82. 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 4,921 feet (1,500 meters), turn
on High Altitude Mode in the Operation menu (see page 71).
If none of these suggestions resolves the problem, contact Epson as described
