■ Circuit Protections This projector is equipped with the following protections to operate in safety. If the abnormality occurs inside the projector, it will turn off the projector by operating one of the following protections. ● Fuse The fuse is located on the ass'y-Inlet. When either the LAMP indicator or the READY indicator is not illuminated, Ass’y Inlet fuse may be opened.
Circuit Protections ● Front cover switch (Door switch) When the front cover is closed, the ready indicator lights orange and the projector cannot be turned on. While operating the projector, if the front cover is closed, Door SW (inside the cabinet) turn off the projector.
ORDER REPLACEMENT LAMP 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 PLV-Z1X ● Replacement Lamp Type No. POA-LMP86 (Service Parts No. 610 317 5355) ■...
■ 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.
Cleaning Cleaning the Air Filter The air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the air filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector.
