Roland SH-1000 keyboard problem

Hello, just thought I'd run this by any experts out there. I'm having a problem with my Roland SH-1000, every time I play the "F" key it plays the note as per normal, but when I release the key it triggers again, but in a slightly out of tune fashion. It only does this on this one note on the higher end of the keyboard, every other key is fine. I've taken it apart and cleaned out the trigger mechanism under the key to no avail. Any ideas appreciated.
Thanks

just a guess. if there are two contacts on each key, check to see (on that note) that the contact controling the ADSR opens before the 'pitch' contact opens (when you release the key).

I was just playing around with the sh-1000 and I noticed the problem is "eliminated" when I set the portamento to "2" (0-10 being the range), which is of course merely getting around it, just thought I'd add this in case it gives away any clues. I'll check that contact suggestion you mentioned later on today Rhino, cheers. Just my luck the F key contact has to be sandwiched between some supports for the keys, whereas every other key contact is easy to get at!
