With maybe a dozen universal remotes over the years, not one was programmed like the others.
In short, if I lost the manual, there was no hope of programming it again if I forgot how.
I have done google searches for instructions on how to program my older tv with an older universal remote control. All the instructions I have found have you pressing buttons that are not on my remote. I may have to buy a new remote unless someone can tell me what to do or a link that I haven't seen.
