this coming....!

Yes, fifty lashes with a wet noodle! Of course I saw it coming, but
it was never much of a problem before, and only happens very rarely.
Main thing is that I live in a typically small and crammed NYC
apartment, with four bicycles, a kayak, some weights and other
miscellaneous exercise equipment, a 52" RPTV, as well as and six six-
foot high bookcases full of, well, books!

chances are the ac adaptor is a sealed unit you'd be better off buying
another with the same voltage and similar spec. be sure to check the
polarity of the litle plug.

I hope it's just the adapter, then...but why would an adapter just
suddenly stop working simply because of being suddenly disconnected??
Of course, I can't imagine why the piano might, either, but that's my
real fear, as it's a ~$1K keyboard....

Then route the cable more safely. put a mat over it if need be.

I only plug it in when it's actually in use...unfortunately, I get so
lost in my musical revelries sometimes that I forget about the cord
and trip over it on my way to the kitchen!

I do that routinely, and it took an $11,000 broken elbow to make me quit
it and buy a $9 length of cable cover. Don't be me.

your problem: it wasn't just a disconnection, it was probably a
healthy yank too. Check to see if your adapter produces power. If not, get
another power supply. If so, it's probably the power jack on the keyboard,
these can usually be replaced if you can find one. Once I had to use a
different type and cut a hole in the case for it and run wires to it from
the PC board - worked fine.

If the jack tests OK, look for built-in fuses or fusible links on the PC
board or power circuits. It is somewhat possible your disconnection
generated a power spike.
