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 personnel injury, servicing should be made with qualified personnel. The following precautions must be observed.

Circuit Protections This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the projector, it will automatically turn off by operating one of the following protection circuits. Thermal switch There is the thermal switch (SW902) inside of the projector to detect 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.
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. Check the following possible causes and wait until the WARNING indicator stops flashing, and then try to turn on the projector.
Maintenance Cleaning the Filter Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes 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 filter immediately. Clean the filter by following the steps below. 1 Turn off the projector, and unplug the AC power cord from the AC outlet.
Maintenance Lamp Replacement When the projection lamp of the projector reaches its end of life, the Lamp replacement icon appears on the screen and LAMP REPLACE indicator lights yellow. Replace the lamp with a new one promptly. The timing when the LAMP REPLACE indicator should light is depending on the lamp mode.
Maintenance Resetting the Lamp Counter Be sure to reset the Lamp counter after the lamp is replaced. When the Lamp counter is reset, the LAMP REPLACE indicator stops lighting and the Lamp replacement icon disappears. 1 Press the MENU button to display the On-Screen Menu. Use the Point 7 8 buttons to move the red framed pointer to the Setting Menu icon. 2 Use the Point ed buttons to move the red framed pointer to Lamp counter and then press the SELECT button.
Maintenance 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. If dirt cannot be removed by air spray, disassemble and clean the optical unit. Cleaning with air spray Disassembly Cleaning 1. Remove the cabinet top following to “Mechanical Disassemblies”. 2.
Security Function Notice Security Function Disable This projector provides security functions such as "Key lock", "PIN code lock" and "Logo PIN code lock". When the projector 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 POWER red/green WARNING red LAMP REPLACE yellow Projector Condition The projector is off. (The AC power cord is unplugged.) Q The projector is preparing for stand-by or the projection lamp is being cooled down. The projector cannot be turned on until cooling is completed and the POWER indicator stops blinking. Q The projector is ready to be turned on with the POWER ON-OFF button.
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 sw.
Troubleshooting No Picture Check following steps. No picture with all of input sources Yes Check signal processing stage and LCD driving stage; Check RGB S&H signals at test points TP35B, TP35G, TP35R1. Check power supply circuit 15.5V and peripheral circuit. Check ICs IC501, IC531, IC561, IC2501, IC2531, IC2561, IC401, IC301 and peripheral circuits. No No picture with PC1 [Digital] input source only Yes Check DVI interface stage; Check IC8001 and peripheral circuit.
Troubleshooting No Sound Check following steps. Check if the audio signal is observed at pins 10 and 21 of IC5001. No Check IC5001 and peripheral circuit. Check 5V_AUDIO, 9V power supply.

Note on Soldering Do not use solder containing lead. This product has been manufactured using lead-free solder in order to help preserve the environment. Because of this, be sure to use lead-free solder when carrying out repair work, and never use solder containing lead. Lead-free solder has a melting point that is 30–40 °C (86–104 °F) higher than solder containing lead, and moreover it does not contain lead which attaches easily to other metals.
