Hello.
Got a long unused CTK-3000 for my kid.
Unfortunately, no sound when:
* pressing the key, nor
* trying to play any song from song bank
Beside of that everything works fine:
* display shows pressed key/note
* notes are displayed during song playback
Of course, I did check if volume is set properly ;)
There is no sound when connect headphones as well. (And nothing in the phone socket)
Is it worth chasing repair or costs will exceed value...?
