Solutions
• Make sure the power plug or connector is connected
correctly.
• Make sure the lamp cover is mounted correctly. For
details, see page 81 "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.
