&Troubleshooting

Maintenance

•If the TEMPERATURE WARNING indicator illuminates, follow the above possible solutions and then wait until the projector has cooled down completely before turning the power back on. (At least 5 minutes.)

•If the power is turned off and then turned on again, as during a brief rest, the LAMP REPLACEMENT indicator may be triggered, preventing the power from going on. Should this occur, take the power cord out of the wall outlet and put it back in again.

Lamp

The lamp in this projector operates for approximately 2,000 cumulative hours, depending on the usage environ- ment. It is recommended that the lamp be replaced after 1,900 cumulative hours of use or when you notice a significant deterioration of the picture and color quality. The lamp usage time can be checked with the On-screen Display (see page 43).

CAUTION

•Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.

•As the usage environment can vary significantly, the projector lamp may not operate for 2,000 hours.
