Resetting or rebooting your cable box is also referred to as power cycling the equipment.  Locate the set top box (cable box) and where it is plugged into electricity. Only remove the power cord from electricity. Leave unplugged for one whole minute. While it is unplugged verify that all the other connections are secure to the Set Top Box. Plug power cord back into electricity. The Set Top Box will take on average about 4-5 minutes for it to come back on fully. While The Set Top Box is rebooting and loading info back into it, stay below channel 72 for the first 20 minutes.
