I'd like to say one huge great thank you to Philip Bradbury. My Humax remote's OK button stopped working last week and a cheaper all purpose remote didn't work to recover my recorded programs. I'm a 66 yr old female techno-phobe but decided to try and follow Philip's advice. It has worked! Brill!!! I used a blunt kitchen knife to open the case as he recommended and washed the buttons. I rubbed the contact for the OK button with an eraser as it was quite black compared to the others. I can't express my gratitude enough.
