I just bought an RCA model F27676BC. I cannot get it programmed to watch cable. The autoprogramming seems to delete channels, not add them. The manual is not online, nor does RCA have it. HELP!

Your TV is from the late 1990's. If you want a free manual there are none. You could Google and pay for a manual from a web site to help with your problem. I tried googling and I found several sites that charge for manuals but they do have them for a fee.

I found some manuals that are close. Check nearby model numbers and see if things are similar.

I used 27" and then looked for a nearby model number.
