Troubleshooting

If the set-top does not perform as expected, the following tips may help. If you need further

assistance, contact your cable service provider.

No Picture

• Verify that the power to your TV is turned on.

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

Note: You should avoid plugging the set-top into an outlet controlled by a wall switch.

• Verify that all cables are properly connected.

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

set-top.

• Verify that the TV is set to the proper input channel.

No Color

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

• Adjust the TV color controls.

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.

• Verify that the mute function is not on.

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.

Note: If you need further assistance, contact your service provider.
