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.
• If the receiver is plugged into a wall switch, verify that the switch is in the ON position.
• 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.
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 peri-
ods of time.
