Performance Tips

If the set-top 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 HDTV is in HD mode. If necessary, run the HD Setup Wizard to select HD mode.

• If the set-top is plugged into a wall switch, verify that the switch is in the ON position.

• Verify that all cables are properly connected.

• Verify that the M-Card module is installed.

• If your system includes a VCR or stereo, verify that you have properly connected them to the

set-top

• Verify that the set-top is set to the proper screen type and resolution.

No Color

• Verify that the current TV program is broadcast in color.

• Adjust the TV color controls.

• If you are using a component video connection (PrPbY), check that all connectors are

completely plugged into the set-top and TV.

No Sound

• If your setup includes a VCR or stereo, verify that you have properly connected them to the set-

top.

• Verify that the volume is turned up (analog audio only).

• Verify that the mute function is not on (analog audio only).

Automatic Software Updates

A message appears on the TV screen when the set-top and the M-Card module are receiving

software updates. In addition, download information also appears on the front panel of the set-top

during these updates. Wait for the current time to display on the front panel before continuing.

When the time appears, the update is complete.
