Safety Instructions Safety Precautions WARNING: The chassis of this projector is isolated (COLD) from AC line by using the converter transformer. Primary side of the converter and lamp power supply unit circuit is connected to the AC line and it is hot, which hot circuit is identified with the line ( ) in the schematic diagram. For continued product safety and protection of per- sonnel injury, servicing should be made with qualified personnel. The following precautions must be observed. 1: An isolation transformer should be connected in the power line between the projector and the AC DO NOT OPERATE THIS PROJECTOR WITHOUT T line before any service is performed on the projec- HE PROTECTIVE SHIELD IN POSITION AND PROP tor.

Page 5: Circuit Protections
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. When the internal temperature reaches near 100˚C, the thermal switch opens to stop the operation of the power supply circuit. The thermal switch cannot be reset itself automatically even if the internal temperature becomes normal. Reset the thermal switch following to the below procedure. How to reset the thermal switch 1. I nsert the sharp tool like a screwdriver into a hole on the cabinet from the cabinet bottom. . P ress the reset button on the thermal switch with the screw- driver.
Page 6: Warning Temperature And Power Failure Protection
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. - I f the WARNING indicator is flashing, it may detect the abnormal temperature inside the projector. Check the follow- ing possible causes and wait until the WARNING indicator stops flashing, and then try to turn on the projector. - I f the WARNING indicator lights red, it may defect the cooling fans or power supply circuits. Check fans operation and power supply lines referring to the chapter “Power supply & protection circuit” in the Chassis Block Diagram section. Possible causes - A ir filters are clogged with dust particles. Remove dust from the air filters by following instructions in the “Air filter care and cleaning” below. - V entilation slots of the projector are blocked. In such an event, reposition the projector so that ventilation slots are not obstructed. - C heck if projector is used at higher temperature place (Normal operating temperature is 5 to 35 ˚C or 41 to 95˚F) the projector is shut down and the WArNING top Control indicator lights red.
Page 7: Maintenance
Maintenance Cleaning the Filter Filter prevents dust from accumulating on the optical elements inside the projector. Should the filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup and adversely affect the life of the projector. If a Filter warning icon appears on the screen, clean the filters immediately. Clean the filters by following the steps below. Turn off the projector, and unplug the AC power cord from the AC outlet. Turn the projector over and remove the filters by pulling the latches upward. Gently clean the filters by using a brush or rinse it softly. When rinsing the filters, dry they well. Replace the filters properly. Make sure that the filters are fully inserted to the projector. CAUtION Filters Do not operate the projector with the filters Pull up and remove. removed. Dust may accumulate on the optical elements degrading picture quality. Do not put anything into the air vents. Doing so may result in malfunction of the projector. reCOMMeNdAtION We recommend avoiding dusty/smoky environments when you operate the projector. Usage in these environments may cause poor image quality. When using the projector under dusty or smoky conditions, dust may accumulate on a lens, LCD panels, or optical elements inside the projector degrading the quality...

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. - W hen all of Led indicators are not lighting, the symptom indicates that the primary power supply circuit does not operate properly. Check the power primary circuit and parts as follow; AC cord, F601 (Fuse), Power board, SW90 (Thermal sw.) short in normal S W90 opens when the surrounding temperature of the switch exceeds 100°C. - When the WArNING (red) and POWer(red) indicators are blinking, the symptom indicates that the projector detected an abnormal temperature risen inside the projector. Check the air filters and remove the object near the intake and exhaust fan openings, and wait until the POWER indicator stops blinking, and then try to turn on the projector. T he internal temperature is monitored by sensor ICs, IC6611(Lamp), IC661 (Panel) on the Main board and IC4831 (Room) on the Temp. board - When the WArNING indicator lights red, the symptom indicates that the projector detected an abnormality in the cooling fan operation or in the power supply secondary circuits. Check fan operation and power supply lines, and the driving signal status.
