Hello,
I have a maybe 15-year-old model that was rarely used but always worked just fine.
Tofay I played it, went through some different sounds and wanted to switch it off.
But it wouldnt power off but showed some number on the display and didnt react anymore.
So I had to disconnect the power and after switching it back on it went into some weird setting, with most buttons not reacting and not playing a sound.
I tried all the troubleshooting tips from the manual without success.
Any ideas what I could do here?
Thanks a lot in advance,
Daniel
