This is the most common reason for missing channels and if your channel scan stops at 13, almost definitely the cause, but you said you're only getting HD channels, which is less common. It ispossible for one outlet to have a problem the others don't, andif the HD channels you get are freezing or tiling, you might have a signalissue. But your TV might also have a setting to only scan for digital channels. You may also have a separate input option for "TV" vs. "DTV" so it may have found both sets of channels but you're only seeing one. If you give us the model number of your TV we can check if Vizio has the manual online so we can see if this is buried in there somewhere.
