Televisions need to go through a process called Channel Scan to allow the television to receive digital channels. Follow the steps below to successfully run a Channel Scan.
Go to the menu screen on the television.
Find a section named Channel or Setup; select Cable.
Look for Auto Channel Search or Channel Scan.
Begin the search or scan for digital and analog channels. The scan can take up to 45 minutes. Allow the channel scan to complete since some channels are added right at the end.
When complete, scroll through some channels to verify that there are digital channels.
Some less expensive TVs sometimes come with a lower quality QAM tuner that may be unable to pick up all the digital channels. Users with less expensive brands such as Dynex and Insignia reported these types of problems.
