  • 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. Led indicator WARNING emit a red light the projector is shut down and the WArNING indicator is blinking red. When the temperature inside the projector reaches a certain level, the projector will be automatically shut down to protect the inside of the projector and the WARNING and POWER indicators start blinking. When the projector has cooled down enough (to its normal operating temperature), the POWER indicator stops blinking and lights red, The projector can be turned on again by pressing the ON/STAND-BY button. Note: The WARNING indicator continues to blink even after the temperature inside the projector returns to normal. When the projector is turned on again, the WARNING indicator stops blinking. Check items - Remove dust around the air filter. - Ventilation slots of the projector are blocked. In such an event, reposition the projector so that ventilation slots are not obstructed. - Check 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 indicator lights red. When the projector detects an abnormal condition, it is automatically shut down to protect the inside of the projector and the WARNING indicator lights red. In this case, unplug the AC power cord and reconnect it, and then turn the projector on once again to verify operation.

(The AC power cord is unplugged.) The projector is in stand-by mode. Press the ON/STAND-BY button to turn on the projector. The projector is operating normally. The projector is preparing for stand-by or the projection lamp is being cooled down. The projector cannot be turned on until cooling is com- pleted and the POWER indicator stops blinking. The projector is in the power management mode. The temperature inside the projector is abnormally high. The projec- tor cannot be turned on. When the projector is cooled down enough and the temperature returns to normal, the POWER indicator stops blinking and the projector can be turned on. (The WARNING indicator keeps blinking.) The projector has been cooled down enough and the temperature returns to normal. When turning on the projector, the WARNING indi- cator stops blinking.

  • Page 53: No Power

    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. Check the power primary circuit and parts as follow; AC cord, F601 (Fuse), Power board, SW902 (Thermal switch) ..short in normal S W902 opens when the surrounding temperature of the switch exceeds 85°C. - W hen 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, IC8821 on the main board and IC8811 on the temp sensor A board, IC8831 on the temp sensor C 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.
