If the receiver does not perform as expected, the following tips may help. If you need further 
assistance, contact your service provider.

•  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.

•  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.

•  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.

•  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.

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.
