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.
