Troubleshooting

Refer to the symptoms and measures listed below before sending the projector for
repairs. If the problem persists, contact your local reseller or service center. Please
refer to "LED Indicator Messages" as well.
Start-up problems
If no lights turn on:
• Be sure that the power connection is correct.
• Press the power button again.
• Unplug the AC adapter and wait for a short while, then plug it in and press the power
button again.
Image problems
If the searching source is displayed:
• Press MENU on the projector or Source on the remote control to select an active
input source.
• Be sure the external source is turned on and connected.
• For a computer connection, ensure your notebook computer's external video port is
turned on. Refer to the computer manual.
If the image is out of focus:
• While displaying the on-screen menu, adjust the focus ring.
• Check the projection lens to see if it needs cleaning.
If the image is flickering or unstable for a computer connection:
• Press MENU on the projector or Menu on the remote control, go to Video/Audio and
adjust Frequency or Tracking.
Remote control problems
If the remote control does not operate:
• Be sure nothing is blocking the remote control receiver on the rear of the projector.
Use the remote control within the effective range.
• Aim the remote control at the rear of the projector.
• Move the remote control so it is more directly in rear of the projector and not as far to
the side.
