							Common Problems
If you think a malfunction has occurred, check the following before contacting your service
representative.
Problem
Solutions
Power does not turn on. • 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.
Power turns off during use. • Make sure the environment in which the projector is
being used is within the acceptable temperature range.
• Make sure the vents are not blocked. 8. Troubleshooting
