I have a Sharp TV that I connect to a cable box. I unluged it to move it and when I plugged it back in it won't get off channel 2. It needs to be on channel 4 but when I click the remote or T.V.'s button to change channels it doesn't work. I've alread did channel search numerous times but nothing is working. Any ideas?
