Cable box gets weird channels....
Starting about a month ago the cable box has been acting very strange. When I turn it on it is on 105, Channel up gives 140, then 132, 185, 256 and so on. It used to be 105, 106, 107, etc.
I've unplugged it and plugged it back in, a couple times, but it doesn't change. The channels aren't random; the same sequence comes up everytime.
Is there anything to do, except have ti replaced?
