These indicators illuminate or flash to warn you about problems that have occurred inside the projector, so if you notice that one of the indicators is on, turn off the power and check the table below for the cause of the problem.

The metal halide lamp has turned off automatically because the internal temperature has risen to an abnormally high level.

It is nearly time to replace the lamp unit.

The metal halide lamp switches off automatically.

The air filter may be blocked.

Does “ LAMP” appear on the screen after the projector is turned on?

The power may have been turned on immediately after it was turned off.

There may be an abnormality in the lamp circuit.

Turn off the main power supply by following the procedure on page 11, and then clean the air filter (refer to page 39).

This occurs when the operation time for the lamp unit is nearing 1,800 hours. Ask your dealer or an Authorized Service Center to replace the lamp unit.

Wait for a while until the lamp unit cools down before turning the power back on again.

Turn off the main power supply by following the procedure on page 11, and then contact an Authorized Service Center.

NOTE:

Be sure to turn off the main power by following the procedure given in “Turning the power on and off” on page 11 before carrying out any of the procedures in the “Remedy” column.

If the main power turns off after the TEMP indicator starts flashing, it means that an abnormality has occurred. Please contact an Authorized Service Center so that the necessary repairs can be made.
