Circuit Protections

Warning temperature and power failure protectionThe 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. Check the following possible causes and wait until the WARNING indicator stops flashing, and then try to turn on the projector. - If 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- Air filters are clogged with dust particles. Remove dust from the air filters by following instructions in the Air filter care and cleaning below. - 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 95F)

Air filter care and cleaningThe removable air filter prevents dust from accumulation on the surface of the projection lens and projection mirror. Should the air filter become clogged with dust particles, it will reduce the cooling fans effectiveness and may result in internal heat build up and reduce the life of the projector.

To clean up the air filters, follow the cleaning procedure below: 1. Turn the power off, and disconnect the AC power cord from the AC outlet. 2. Turn the projector up side down and remove air filters by pulling the latches of it upward. 3. Clean the air filters with brush or wash out the dust and particles. 4. Replace the air filters properly. Make sure that the air filters are fully inserted.

TroubleshootingNo PowerThis projector provides a function which can be specified a defective area simply by indicating the LEDs on the control panel. 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 sw.) ......short in normal SW902 opens when the surrounding temperature of the switch exceeds 90C.

- When the WARNING (red) and POWER(red) indicators are flashing, 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 flashing, and then try to turn on the projector.The internal temperature is monitored by sensor ICs, IC2801, IC2831 and IC2861 on the Main 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.The P_FAIL signal (Error: L) is sent to pin 48 of IC801 when the abnormality occurred inside the projector, and then the IC801 sends the shut down signals, 5V_SW and LAMP_BST_SW, to the power supply circuit to stop the operation. An abnormality occurs on the secondary power supply; Check power supplies 15.5V, S15.5V, S6V, S-5V. P_FAIL signal becomes Low when the abnormality occurs on any of the power supply lines. An abnormality occurs on the fan control circuit; Check FN901, FN902, FN903, FN904, FN905, FN906 and peripheral circuit. Check Q67P, D67P, Q68P, D68P and peripheral circuit (Over voltage detection circuit). An abnormality occurs on the drive signals; POWER_SW signal (Power-on: H) is output from pin 1 of IC801 and input to pin 17 of IC1881, and output from pin 3 by the name of 5V_SW. LAMP_BALAST_SW1(Power-on: H) is output from pin 12 of IC1851(D/A) and supplied to the P.F Control IC, IC621, through the IC1881, Q651, and PC643. BALAST_AC signal (Power-on: H) is output from pin 39 of IC801 and input to pin 11 of IC1881, and output from pin 9 by the name of BALAST_AC1. BALAST_AC1 signal is applied to pin 2 of IC4891 and output pin 4 and then supplied to the lamp balast unit through the Lamp Cover switch(SW901). CHO_RXD signal at the pin 77 of IC801 is applied from the lamp balast unit. If the abnormality occurred on the lamp balast unit, CHO_RXD(LAMP_DET) signal becomes High and then IC801 shuts down the power supply circuit.

Lamp Cover switchMake sure that the lamp cover is mounted correctly. If not or the lamp cover removed, the lamp does not light on for the safety. Check the lamp cover and lamp cover switch (SW901).

Reset switchThe microprocessor inside the projector may occasionally malfunction and does not accept any controls. In this case, press the reset switch on the rear panel with a sharp tool to restart the projector.
