Circuit Protections When both of the WARNING TEMP. and READY Indicators are flashing: When the projector detects an internal problem, it will shut down FRONT INDICATORS automatically and both of the WARNING TEMP. and READY Indicators starts flashing. In this condition, the projector cannot be turned on even if you press LAMP READY the POWER ON-OFF button on the remote control unit or on the side control.
Page 7: Air Filter
Circuit Protections When the WARNING TEMP. Indicator is flashing: The WARNING TEMP. Indicator flashes red to let you know the internal FRONT INDICATORS temperature of the projector exceeds the normal level. If the temperature goes up further, the projector will be turned off automatically and the Ready indicator LAMP READY will go out.
Page 8 Circuit Protections ● Temperature Monitor System ■ To control the driving power of the cooling fans. This projector detects internal temperature and automatically controls operating power of cooling fans. The CPU checks the temperature and atmospheric pressure inside a projector. It checks a temperature using temperature sensor-IC5801and it checks an atmospheric pressure using pressure sensor-IC886.
Page 9: Lamp Replacement

Page 11: Lamp Replace Counter
Replacement Lamp can be ordered through your dealer. When ordering a Projection Lamp, give the following information to the dealer. ● Model No. of your projector PLC-XF46N / PLC-XF46E ● Replacement Lamp Type No. POA-LMP100 (Service Parts No. 610 327 4928)
Page 12: Lamp Handling Precautions
Lamp Replacement LAMP HANDLING PRECAUTIONS This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling may result in accidents, injury, or create a fire hazard. ● Lamp lifetime may differ from lamp to lamp and according to the environment of use. There is no guarantee of the same lifetime for each lamp.
Page 13: Maintenance And Cleaning
■ Maintenance and Cleaning After long periods of use, dust and other particles will accumulate on the LCD panel, prism, mirror, polarized glass, lens, etc., causing the picture to darken or color to blur. If this occurs, clean the inside of optical unit. Remove dust and other particles using air spray.
Page 14: Air Filter Care And Cleaning
Maintenance and Cleaning AIR FILTER CARE AND CLEANING Air Filter prevents dust from accumulating on surface of Projection Lens and Projection Mirror. Should Air Filter become clogged with dust particles, it will reduce Cooling Fans' effectiveness and may result in internal heat build up and adversely affect life of a projector.
