Problem | Check These Items | |
Does not turn on | • | Check that the power cord is plugged in and that the power button on the projector cabinet or the remote control |
or shut down |
| is on. (→ pages 19 and 20) |
| • Ensure that the lamp cover is installed correctly. (→ page 83) | |
| • Check to see if the projector has overheated. If there is insufficient ventilation around the projector or if the | |
|
| room where you are presenting is particularly warm, move the projector to a cooler location. |
| • Check to see if you continue to use the projector for another 100 hours after the lamp has reached the end of its life. | |
|
| If so, replace the lamp. After replacing the lamp, reset the lamp hours used. (→ page 79) |
| • | The lamp may fail to light. Wait a full minute and then turn on the power again. |
| • | Set [FAN MODE] to [HIGH ALTITUDE] when using the projector at altitudes approximately 5500 feet/1700 |
|
| meters (3000 feet/900 meters on V300X/V300W) or higher. Using the projector at altitudes approximately 5500 |
|
| feet/1700 meters or higher without setting to [HIGH ALTITUDE] can cause the projector to overheat and the |
|
| projector could shut down. If this happens, wait a couple minutes and turn on the projector. (→ page 70) |
|
| If you turn on the projector immediately after the lamp is turned off, the fans run without displaying an image |
|
| for some time and then the projector will display the image. Wait for a moment. |

|
| than approximately 5500 feet/1700 meters (3000 feet/900 meters on V300X/V300W) and setting to [HIGH |
