Projector Problems
The projector stops responding to all controls
If possible, turn off the projector, then unplug the power cord and ` `
wait at least 20 seconds before reconnecting power.
Lamp burns out or makes a popping sound
When the lamp reaches its end of life, it will burn out and may ` `
make a loud popping sound. If this happens, the projector will not
turn on until the lamp module has been replaced. To replace the
lamp, follow the procedures in the “Replacing the Lamp” section
on pages 49.
Remote Control Problems
If the remote control does not work
Check the operating angle of the remote control is within ±30° ` `
both horizontally and vertically of one of the IR receivers on the
projector.
Make sure there are not any obstructions between the remote
` `
control and the projector. Move to within 7 m (±0°) of the projector.
Make sure the batteries are inserted correctly.
` `
Replace batteries if they are exhausted. ` `
Sound Problems
If no sound from the projector
If you are playing an external source, make sure you have an ` `
audio cable securely connected between the source device and
the projector’s audio input.
Please make sure the external speakers are not connected.
