Problems with the Projector
121
If the Source button is pushed to switch video input sources and no
source is connected, the projector enters a cool-down mode
(flashing orange power light) and then goes into sleep mode (steady
orange power light). Connect a video source, then press the Power
button to resume.
◗
The power light does not come on.
Turn off the projector, check that the power cable is connected
securely both at the electrical outlet and the projector, and press the
Power button again.
◗
Projected images get darker or start to deteriorate, or the
projection lamp light is red.
Replace the projector lamp as described in Chapter 5.
◗
The temperature light is red.
The projector is overheating, which turns the lamp off
automatically. Let the projector cool for a few minutes, then turn it
back on. Make sure nothing is blocking the ventilation vents.
The air filter may be clogged. Clean it as described in Chapter 5 and
then let the projector cool for awhile.
If the projector continues to overheat after you clean the air filter,
the problem may be caused by damage to the cooling fan or internal
circuits. Contact a qualified service person.
