The Comcast Digital Transport Adapter, or DTA, facilitates the connection between your television, VCR or DVD player and your cable wall outlet to provide premium cable channels. Resetting will correct a number of issues including a lost signal, frozen channels or channels that display a blue screen. Once the device is reset, it may take several minutes to refresh and for your display to return.
Locate the reset button on your Digital Adapter. The button will be located on the front or back of your device and will be marked "Reset."
