I have a Yamaha PSR-280 keyboard which I bought about 4 or 5 years ago.
It still plays well and is in very good condition. However I noticed
some of the black keys in the lower register particularly seem to have
some play to them when moved from side to side, and sometimes make a
clicking noise when I'm playing them within the context of a piece of
music. Is this a normal occurence from use of the keyboard over time?
Thanks.
