indicator

The warning lights on the projector indicate problems inside the projector.

There are two warning lights: a TEMPERATURE WARNING indicator which warns that the projector is too hot, and a LAMP REPLACEMENT indicator which lets you know when to change the lamp.

If a problem occurs, either the TEMPERATURE WARNING indicator or the LAMP REPLACEMENT indicator will light up red. After turning off the power, follow the procedures given below.

If the TEMPERATURE WARNING indicator lights up, 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.

&Troubleshooting

Maintenance

Lamp

It is recommended that the lamp be replaced after approximately 1,000 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. (As the usage environment can vary significantly, the projector lamp may not operate for 1,000 hours.)

CAUTION

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