When the life of the projection lamp draws to an end, the LAMP REPLACE indicator lights yellow. Whenthis indicator lights yellow, replace the projection lamp with a new one promptly. Reset the Lamp replacecounter after replacement of the lamp.
The projector is OFF. (The AC power cord is unplugged.)
The projector is preparing for stand-by or the projection lamp is beingcooled down. The projector cannot be turned on until cooling is completed.
The temperature inside the projector is abnormally high. The projector can-not be turned on. When the projector is cooled down enough and the tem-perature returns to normal, the POWER indicator lights red and the projec-tor can be turned on. (The WARNING . indicator keeps flashing.) Check andclean the Air filter.

No Power
- When all the LED indicators are not lighting, the symptom indicates that the primary power supply circuitdoes not operate properly. Check the power primary circuit and parts as follow;
AC cord, F601 (Fuse), Power board, SW902 (Thermal sw.) short in normalSW902 opens when the surrounding temperature of the switch exceeds 90°C.
This projector provides a function which can be specified a defective area simply by indicating the LEDs on the con-trol panel. Connect the AC cord and press the Power button once and then check the LED indication.
- When the WARNING (red) indicator lights, the symptom indicates that the projector detected an abnormalityin the cooling fan operation or in the power supply secondary circuits. Check fan operation and power supplylines, and the driving signal status.
An abnormality occurs on the secondary power supply lines.Power failure detection diodes detect abnormal voltage on the power supply circuits.POWER_FAIL (Error:L) signals are sent to pin 174 of IC301(System Controller) via IC1871(Comparator).Check the shortage of secondary circuits, ICs, condensers, etc.Check power supply lines, 15VP, 9V, 12V, 3.3V and 1.8V, 5V_AUDIO, S5V on the Main Board.
An abnormality occurs on the fan control circuits.Power failure detection diodes detect the fan operation stop. Check FN901, FN902, FN903, FN904, FN905,FN906 and peripheral circuit.Check fan's power supply lines and detection diodes D3616 and D3614.Check fan lock signal(Lock:H) and Q3601, D3617 and peripheral circuit.
An abnormality occurs on power starter signals (ON_5VA, ON_3.3V, ON_15V, LAMPDC_ON, DC_ON).LAMDC_ON signal (Power-on:H) is output from pin 15 of IC1803 and applied to PC643 on the PowerBoard. It drives the power oscillation circuit and power supply in the Power Board.DC_ON signal (Power-on:H) is output from pin 16 of IC1803 and switches Q661<15.5V> on/off.ON_15V signal(Power-on:H) is output from pin 72 of IC301 and sent to Q2501, then 15VL line is supplied.ON_5VA signal(Power-on:H) is output from pin 71 of IC301 and sent to IC5081 and Q3582 to switch powersupply 5V_AUDIO and 5VA.
- When the WARNING(red) and POWER(red) indicators are flashing, the symptom indicates that the projec-tor detected an abnormal temperature risen inside the projector. Check the air filters and remove the objectnear the intake and exhaust fan openings, and wait until the POWER indicator stops flashing, and then try toturn on the projector.
The internal temperature is monitored by sensor ICs, IC8811, IC8821 and IC8831 on the Main Board.
Reset switchThe microprocessor inside the projector may occasionallymalfunction anddoes not acceptany controls. Inthis case, pressthe reset switch onthe rear panel witha sharp tool torestart the projec-tor.
Lamp Cover switchMake sure that the lamp cover is mounted correctly. If not orthe lamp cover removed, the lamp does not light on for thesafety. Check the lampcover and lamp coverswitch (SW901).
Troubleshooting
- When the projector switches into the standby mode.An abnormality occurs on Lamp drive signal (LAMP_POW, LAMP_ERR).
- LAMP_POW signal(Power-on:H) is output from pin 140 of IC301 and sent to IC4811 via IC4852.SCEL signal(Lamp-on:L) is output from pin 2 of IC4811 via IC4801 and sent to Lamp Ballast Unit throughSW901(Lamp Cover SW).
- TXL signal is output from pin 12 of IC4811 and sent to Lamp ballast Unit via IC4801.(TXL signal is applied for lamp power control. Lo: Low power, Hi: High power)
- RXL signal(Lamp status signal) is output from Lamp Ballast Unit and sent to pin 9 of IC4811 via IC4801,then LAMP_ERR signal is output from pin 3 of IC4811 and sent to IC301 via IC1811.If an abnormality occurs on the lamp ballast unit, RXL signal and LAMP_ERR signal become "H" and thenIC301 sets the projector into the standby mode..

Cleaning
Cleaning with air spray
1. Remove the cabinet top following to “MechanicalDisassemblies”.
2. Clean up the LCD panel and polarizing plate by usingthe air spray from the cabinet top opening.
Caution:Use a commercial (inert gas) air spray designed forcleaning camera and computer equipment. Use a resin-based nozzle only. Be vary careful not to damage opti-cal parts with the nozzle tip. Never use any kind ofcleanser on the unit. Also, never use abrasive materialson the unit as this may cause irreparable damage.
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. If dirt cannot be removed by air spray, disassemble and cleanthe optical unit.
Disassembly Cleaning
Disassembly cleaning method should only be per-formed when the unit is considerable dirty and cannotbe sufficiently cleaned by air spraying alone.Be sure to readjust the optical system after per-forming disassembly cleaning.
1. Remove the cabinet top and main units following to“Mechanical Disassemblies”.
2. Remove the optical base top following to “Optical UnitDisassemblies”. If the LCD panel needs cleaning,remove the LCD panel unit following to “LCD panelreplacement”.
3. Clean the optical parts with a soft cloth. Cleanextremely dirty areas using a cloth moistened withalcohol.
Caution:The surface of the optical components consists of mul-tiple dielectric layers with varying degrees of refraction.Never use organic solvents (thinner, etc.) or any kind ofcleanser on these components.Since the LCD panel is equipped with an electronic cir-cuit, never use any liquids (water, etc.) to clean the unit.Use of liquid may cause the unit to malfunction.
