From the model number it looks like one of the remotes that comes with the cable box, is this true? If so, it should work with the cable box, to change the channel, bring up the menu, etc, without any programming needed. It just wont do TV functions, like powering the TV on/off and volume.I would see if the remote works on other boxes(not TVs). If it does, then probably something wrong with the box. If it doesn't work with other boxes, then probably something wrong with the remote and need to bring it back or some how get a new one.
As for programming the remote, what is the model number of your TV and any other A/V equipment you want to program the remote for?
