8. Troubleshooting Common Problems If you think a malfunction has occurred, check the following before contacting your service representative. Problem Power does not turn on. Power turns off during use. Solutions • Make sure the power plug or connector is connected correctly. • Make sure the lamp cover is mounted correctly. For details, see page 159 "Replacing the Lamp". • When projecting an image on the tabletop, be sure to press the [Power] button and wait until the projector cooling process completes before disconnecting the power cord. If you disconnect the power cord without pressing the [Power] button or the projector's power is turned off suddenly due to a power outage, you cannot turn the projector back on for up to approximately 25 minutes because it needs to release the internal heat. Wait until the projector cools down. • Make sure the environment in which the projector is being used is within the acceptable temperature range. • Make sure the vents are not blocked. 148
