I have a Casio Casiotone CT-660 to repair. The last 7 keys do not work, plus the LED lights are unstable, so something with the electronics too, I guess. Any chance to get it repaired? Who? Where? Thanks!

What country/city are you in, so people can suggest a repair shop near you?
Wrocław
Are you looking for a local repair person only, or also troubleshooting advice-and did the problem start suddenly (for example after storage, transport, spill, or power issue)?
I'm looking for both, and the problem started after I accidentally dropped the keyboard.
