The switch from analog to digital is here. Television stations are still changing their channels, and thus, if you have a converter box, you should be rescanning your converter boxes periodically to update these new channels. Scanning searches for and “remembers” the available digital broadcast channels. But in some cases where stations moved their digital frequencies on June 12, simple scanning may not be enough. There is a procedure – sometimes called “double rescanning” – that can clear your box’s memory of saved channels. These earlier scans may have saved channel information that is now incorrect. The following is from the DTV website regarding five simple steps to a double rescan for a converter box or digital TV:
- Disconnect the antenna from the box or digital TV.
- Rescan the box or digital TV without the antenna connected. As with any scan follow the on-screen instructions or owner’s manual for your device.
- Unplug the box or digital TV from the electrical outlet for at least one minute.
- Reconnect the antenna to the box or digital TV and plug the unit into the electrical outlet.
- Rescan the box or digital TV one more time.
