I have an old RCA television that I picked up from Goodwill for my kids, it didn't come with a remote control, I assume it was lost. There are no buttons on the tv to program the channels and I can't figure out how to get to the line in channel, I can't hook up the DVD player or the video game. I can't figure out how the code in the Universal remote works. I have the RCA Universal Remote but it won't work on the T.V. Section, only the VCR section which doesn't program the T.V. Is there a code to manually program the remote to the T.V. part of the T.V. Or is there a way to program the T.V. Directly?
