How to Reboot a Cable Converter After a Power Failure


Cable converter boxes typically revert to the factory settings when the electrical connection is cut to the component, such as during a power failure. Rebooting the box clears the component's memory so that the user can reprogram the digital channels and continue watching television. This two-step process takes only a couple of minutes. Depending on the converter-box model, it may take longer for the equipment to reprogram the available channels than it will to reboot.

  • Unplug the AC power cord from the back of the converter box, and wait at least 10 seconds before plugging the cord back into the box.

  • Disconnect the coaxial cable from the converter box by turning the coupler on the end of the cable counter-clockwise to remove it from the jack.

  • Press the "Scan," "Auto-Tuning" or "Auto-Scan" button, depending on the converter box model, while the cable is disconnected from the box. This will completely clear the memory.

  • Reconnect the coaxial cable by turning the coupler clockwise over the external threads on the converter box jack.

  • Press the "Scan" button once again to reprogram the box with all available cable channels after rebooting the component.

Tips & Warnings

  • Plugging the converter box into a surge protector can prevent damage to the component during an electrical storm that can lead to a power outage. The box may still need to be rebooted, but it is less likely to sustain internal damage when connected to a surge protector.
  • The coaxial cable must be removed from the converter box during the initial rescan to clear the memory so the box will reboot.
