About a year ago, I posted to this forum to say that I was having a problem with my PX-5S where it wouldn't boot up--instead it would display the "No Media" error. I followed Mike's advice and installed the 1.11 firmware update, which had just been released. That seemed to fix the problem, at least for a time. But then recently I've again encountered this same problem, twice. The first time I reinstalled 1.11, which worked for that session. But then the next time I attempted to boot up the keyboard, day before yesterday, again I got the same error. This time I checked online, found the 1.12 update, and installed that. I ran Initialize All, rebooted, and all was well. That's good, but really, the piano shouldn't be losing its firmware or its memory, or whatever setting controls this. Does this behavior indicate some kind of a hardware issue? Perhaps a bad chip? It's very disconcerting when this happens at a practice, or worse, at a gig! Has anyone else encountered this issue? Any thoughts or advice as to how I should proceed to make sure it doesn't happen again? Thanks! Saul
