110 Problem SolvingIf you are having a problem with the projector, first check the projectors indicators while referring to Reading the Indicators below. If the indicators do not show clearly what the problem might be, refer to When the Indicators Provide No Help. p.113Reading the Indicators The projector is provided with the following three indicators. These indicators notify you of the operating status of the projector. The following tables show what the indicators mean and how to remedy the problems that they indicate. : lit : flashing : off Status Cause Remedy or Status Internal error Stop using the projector, disconnect the power cable from the electrical outlet, and contact your dealer or the nearest address provided in the International Warranty Conditions section of the Safety Instructions/World-Wide Warranty Terms booklet. Fan related error/Sensor error Stop using the projector, disconnect the power cable from the electrical outlet, and contact your dealer or the nearest address provided in the International Warranty Conditions section of the Safety Instructions/World-Wide Warranty Terms booklet. Lamp indicatorOperation indicatorTemperature indicator RedRedRedRedRed
111 Problem Solving Lamp cover is open error/ Lamp timer failure/ Lamp out Take out the lamp and check if it is broken. Replacing the Lamp p.125 If the lamp is not broken, put it back in and then turn the power on. If the lamp still does not turn on, replace it with a new lamp. If this does not solve the problem, stop using the projector and disconnect the power cable from the electrical outlet. Then contact your dealer or the nearest address provided in the International Warranty Conditions section of the Safety Instructions/World-Wide Warranty Terms booklet.If the lamp is broken. Contact your local dealer for further advice. (Projection cannot be carried out until the lamp is replaced.)Check that the lamp and the lamp cover are securely installed. If the lamp or lamp cover is not securely installed, the lamp will not switch on. Internal temperature error (overheating) The lamp will turn off automatically and projection will stop. Wait for about 5 minutes without operating the projector. After confirming that the projector enters Standby state, check the following two points. When done the checking, press the [Power] button to turn the power back on. Check that the air filter and air exhaust vent are clear, and that the projector is not positioned against a wall. p.16 If the air filters are blocked, clean or replace them. p.123 If the projector continues to overheat even after the above points have been checked, or if the indicators show a problem when the power is turned back on, stop using the projector, disconnect the power cable from the electrical outlet, and contact your dealer or the nearest address provided in the International Warranty Conditions section of the Safety Instructions/World-Wide Warranty Te r m s booklet. High-speed cooling in progress (This is not an abnormality, However, if the temperature rises too high again, projection will stop automatically.) Check that the air filters and air exhaust vent are clear and that they are not up against a surface such as a wall. p.16 If the air filter is blocked, clean it. p.123 Lamp replacement notification Replace the lamp with a new one. p.125 If you continue to use the lamp after it has passed the replacement period, the possibility that the lamp may break will increase. Replace the lamp with a new one as soon as possible. * The indicator status will vary depending on the projector status at the time. : lit : flashing : off Status Cause Remedy or Status RedRedRed RedRedOrange Orange
112 Problem Solving If all indicators are switched off, check that the power cable is connected correctly and that power is being supplied normally. Standby condition (Not abnormal) Press the [Power] button on either the remote control or the projectors control panel to start projection. When turning off the projectors power, disconnect the power plug from the electrical outlet when the projector is in this condition. Warm-up in progress (Not abnormal) Please wait. Warm-up time is approximately 30 seconds. After warm-up is complete, the flashing green indicator changes to steady green. Projection in progress (Not abnormal) Cool-down in progress (Not abnormal) Please wait. The cool-down g period lasts about 20 seconds. (This varies depending on factors such as the ambient air temperature.) You cannot operate the [Power] button on either the remote control or the projectors control panel during cool-down. Press the button again after cool-down ends and the indicator changes to steady orange. : lit : flashing : off Status Cause Remedy or Status OrangeGreenGreenOrange TIP If the projector is not operating properly even though the indicators are all showing normal, refer to When the Indicators Provide No Help.
