It is possible that the remote buttons are starting to fail. Most remotes these days don't really have mechanical button switches inside, but instead have PC board traces, which form a closed contact when the conductive rubber behind each button presses against them. It is possible to disassemble most of these remotes and clean the contacts. Usually all the buttons are together on one big piece, and all the conductive rubber pads will be easy to see. Clean all of it with alcohol and q-tips, (93% or better), and clean all the PC board traces too. Hardest thing is putting it all back so everything lines up exactly. The older the unit, the more likely this is the problem. Treat the remote to new batteries while you're at it, and you just might have solved your problem for another couple years.
