same problem on Yamaha RX-V650 remote. but it's quite easy to repair it.
+
1. open battery housing and remove the batteries
+
2. remove the screw located in the center of the battery housing
+
3. top and bottom shell of the remote are held together by 4 latches per side. the most fore and aft ones are located about 1cm from each end. pry them open w/ a small flat head. if you're carefull that will leave only tiny scratches, but it does take some force
+
4. once open, remove the insides and clean them from all the drinks and what not that has been poored over the remote (mine was full of... stuff)
+
5. if necessary, at contact spray or alike to the buttom of the rubber buttons
+
6. put it all back together again. you might need some new batteries as well. should work like a charm
