Hi,
I've had a PX-160 since December and in general have been pretty happy with it. However, after two months the middle C and F above it felt noticeably more loose and clattered a bit. Since then a few other keys have had a similar feeling. Is this a normal/expected occurrence as the piano is played or is it something to be concerned about? (On a related note, I also had an issue where the speakers didn't come back on after using and removing headphones. Reinserting/removing the headphones and turning the unit off and on fixed it. That hasn't happened in a month or so, however).
In general, while I find these issues concerning and noticeable/somewhat distracting while playing, they haven't been enough of a problem to send the piano in for repair, particularly as I'll guess factory repair would take some time and this is my only piano. Thanks.
