Remote has become dysfunctional because on off button, made of rubber, sticks and releases all the time. Takes multiple "clicks" to turn the receiver on and it often turns itself off if the on/off button sticks in the pushed in position, then pops back up. Has become a major irritation. Am looking for a used remote of the same model, that works properly, to replace it. As an alternative, if someone can tell me how to repair the button, that would be great. I don't have a clue as to separate the remote top and bottom - there's no obvious slot or lever that looks like it would open the remote. Figuring I couldn't do any more damage, I gave the on/off button a brief shot of WD 40 silicone lubricant, but it still sticks. Any advice would be appreciated.
