I have a universal remote, I believe my father has the manual but he can't find it, it's an old AT&T one, according to [Link: replacementremotes.com] it is a AT&T MKT477A00 Remote Control. I figured out from memory and logic how to set codes, but I don't know what codes I need, other than that they're four digit. I'm attempting to make it work with a Panasonic tv, a CT-25G7F, if it makes any difference.
