If your cable television is giving you trouble, you can call up your cable company and ask the rep to send what are known as “reset codes” to your cable box. Here are some that we found:

Reset: Resets your cable box
Warm Reset: Turns the cable box off, then on.
CCV Hit (Cable Card Host Validation): if you have a cabe card, resets your premium channels (can get them to start working) Can screw up your system if you don’t have a cable card.

More specifically, if you look up your cable box’s product name in Wikipedia, there will usually be a section called Diagnostic Codes. The codes are escalating and the entries should say what it does and whether it has any negative side effects.
