Troubleshooting
If the receiver does not perform as expected, the following tips may help. If you need
further assistance, contact your service provider.
No Picture
• Verify that the power to your TV is turned on.
• Verify that your wireless receiver and wireless access point are powered on.
• Verify that all cables are properly connected.
• If your system includes a VCR, DVD recorder, or stereo, verify that you have properly
connected the device to the receiver.
• Verify that you are using the proper input selection to the home theater receiver or TV.
• Verify that the receiver is set to the proper screen type and resolution.
• If you are using coaxial cable to connect to your TV, verify that the TV is tuned to the
channel designated by your service provider (usually channel 3). Contact your service
provider for the channel information.
Wireless Receiver Signal Strength
• Verify that you are able to receive wireless signal. See
page 11
for details.
• Optimal operating conditions for wireless receivers can vary. Performance depends
on many factors, including distance from the access point, building materials,
interference, and other environmental conditions.
No Color or Incorrect Color
• Verify that the current TV program is broadcast in color.
• Adjust the TV color controls.
• If you are using a component video connection (YPbPr), check that all connectors are
completely and properly plugged into the receiver and TV.
• If you are using a component video connection (YPbPr) and your HDTV has only RGB or
RGB-HV connectors, you must use an adapter. You can obtain the adapter through an
electronic parts retailer.
No Sound
• If your setup includes a VCR, DVD recorder, or stereo, verify that you have properly
connected the device to the receiver.
• Verify that the volume is turned up.
• Verify that the mute function is not on.
• Verify the proper input selection to the home theater receiver or TV.
• If you are using coaxial cable to connect to your TV, verify that the TV is tuned to the
correct channel.
Avoid Screen Burn-In
Images such as letterbox bars or side bars, bright closed-captioning backgrounds, station
logos, or any other stationary images may cause the display in your HDTV to age
unevenly; this is known as screen burn-in. Refer to the owner’s manual that came with
your HDTV for more information.
CAUTION: Avoid screen burn-in. Do not display the same fi xed images on
your HDTV screen for extended periods of time.
