My sky+remote became increasingly difficult to use, so I got a replacement. I still have the old one and thought that I would see if I could repair it, and keep it in reserve. When I opened it the contact area between the press buttons and the main board seemed to be covered in a transparent oil. I put it together, and it still works but you have to push the buttons down very hard for them to work. Am I being mean in trying to repair the remote instead of throwing it away? If not has anybody got any ideas?
