Digital Television: Do You Need to Rescan?
If you’re enjoying free over-the-air TV with an antenna, you might be missing out on channels. Periodically rescanning your TV ensures you receive all available local broadcasts. This simple process is the same one you used when initially setting up your TV or converter box. You might be surprised by the number of new channels you discover!
Why Rescan for Digital TV Channels?
Broadcasters occasionally change their frequencies, and new channels may be added in your area. Rescanning your digital television allows your tuner to locate these updated frequencies and add any new channels to your lineup. Think of it as refreshing your channel list to reflect the current broadcasting landscape.
The FCC’s DTV reception map can help you determine which channels are available in your location. Input your address to see a detailed list of broadcasters and their signal strength in your area. This tool helps you optimize your antenna placement for the best possible reception.
How to Rescan Your TV
Rescanning your TV is a straightforward process, though the exact steps may vary depending on the brand and model of your television. Common terms for this process include “auto-tuning,” “channel set-up,” “channel scan,” “channel search,” “auto-scan,” and “auto-program.”
Generally, the process involves accessing your TV’s menu using your remote control and selecting the option to scan for channels. Your TV will then automatically search for available broadcasts and update your channel list.
Consult your TV or converter box owner’s manual for detailed instructions specific to your device. You can also often find these instructions on the manufacturer’s website under support or FAQs.
