My keyboard sounds the same as this one: It's the same problem, and the ct-s300 is basically the same as the lk-s250. I think it's a normal sound, because i hear the same thing on my computer, when the headphones are plugged. I contacted Casio, but they didn't answer. It's that buzzing sound that can be heared when speakers are turned on.

I think i'm going to contact Casio about this sound then.

Yes it is, not even 1 month old. I feel kinda sad that it's like this, because it's a very fun keyboard. I thought that it was normal because other speakers make the same sound, i even read some topics on this forum about static. Maybe it's something related to electric grounding?

Yes it is, and i tried it with the AC adapter, the AA batteries, in another outlet, everything. Tried with headphones and the same static is there.

I turned off all the electronics in the room (router, phone, computer, everything) and it's still making the noise, is it a problem on the keyboard?

I have my computer and my phone near it, and i normally use my keyboard with AA batteries but when i use the power supply, it's the only thing connected to it

My keyboard speakers make a buzz (like a static noise) when i'm not playing it, is it normal?

I got a Casiotone LK S250 yesterday (never had a keyboard before). I selected the Stereo Grand Piano sound and it is stronger in the speaker on the right. Is it broken or it's just the sound?
