we have hooked up uor converter box and nothing is happening? we did all of the steps in the leaflette, but onthe t.v all you see is a message that says, "unable to auto tune this channel, try moving antenna, to start going through channels " something along those lines! anyways we can't change the channel or nothing! we also have a really old pair of rabbit ears that are bearly hangin on anyways, could that also be part of the problem?
