Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the pro- jector, it will automatically turn off by operating one of the following protection circuits. Thermal switch There is the thermal switch (SW90) inside of the projector to de- tect the internal temperature rising abnormally.
Circuit Protections Warning temperature and power failure protection The projector will be automatically turned off when the internal temperature of the projector is abnormally high, or the cooling fans stop spinning, or the power supplies in the projector are failed. - If the WARNING indicator is flashing, it may detect the abnormal temperature inside the projector.
Lamp Replacement Lamp replacement order rePLAceMeNt LAMP Type No. Parts No. WArNING: POA-LMP115 610 334 9565 - For continued safety, replace with a lamp assembly of the same type. Screw Lamp Cover - Allow the projector to cool for at least 45 minutes before you open the lamp cover.
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.
Security Function Notice This projector provides security functions such as "Key lock", "PIN code lock" and "Logo PIN code lock". When the pro- jector has set these security function on, you are required to enter correct PIN code to use the projector. If you do not know the correct PIN code to the projector, the projector can no longer be operated or started.

Troubleshooting Indicators and Projector Condition Check the indicators for projector condition. Indicators LAMP Projector condition PoWer WArNING rePLAce red/green yellow The projector is off. (The AC power cord is unplugged.) The projector is preparing for stand-by or the projection lamp is being cooled down.
Troubleshooting No Power This projector provides a function which can be specified a defective area simply by indicating the LEDs. Connect the AC cord and press the Power button once and then check the LED indication. - When all of Led indicators are not lighting, the symptom indicates that the primary power supply circuit does not operate properly.
Troubleshooting No Picture check following steps. No picture with all of in- put sources Check signal processing stage and LCD driving stage; Check RGB S&H signals at test points TP_B1, TP_G1, TP_R1. Check power supply circuit 15.5V and peripheral circuit. Check ICs IC501, IC531, IC561, IC501, IC531, IC561, IC401, IC301 and peripheral circuits.
