Programing a Phillip Magnavox color TV before remotes
How do you program the channels on a color Phillips Magnavox TV before they had remotes? This TV has a off&on button a volume button and a channel up and down button. There are no other button any where, front or back. It never had a remote. It is programed now to get channels 3, 4, 5, and 13. It has a great picture but we would like to add more channels.
