Casio CTK-3000: Static in right speaker and low volume in left speaker.

Sun, 20 Dec 2020 09:24:01 -0700

Hi. My father has a Casio CTK-3000 which he has owned for a few years. He turned it on today for th first time in several months and now there is static in the right speaker and low volume on the left speaker. We've tried connecting to an amp and the static is still there. We have even tried plugging it into a different outlet and still the same result. While it was not being used, it was covered.

Does anyone have any ideas what might be causing this. Thank you.

Casio CTK-3000: No sound at all

Tue, 24 Oct 2023 09:11:42 -0700

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...?
