Question about Casio Music

Open Question

My Casiotone MT-46 is having sound and volume problems! Need help to get the keys to make noise.

Just received a Casiotone MT-46 from a friend who warned me it might not even turn on, but I'm determined to fix it! It turns on and when plugged into my speaker system, makes a low humming noise on certain settings. Humming changes pitch and volume slightly when any keys between C and F are pressed (C, C#, D, D#, E, F, all octaves). The built in speaker makes no noise whatsoever. Any way to fix it, or is this thing a goner?

Thank you for the info. I would suggest to take it back from where you bought it from if the store will allow a 90 days return and replace it for a new one, or you can contact Toshiba to get it fixed under warranty. There should not be any humming noise on the speakers.

How to repair a casiotone MT-520


Did all those keys fail at once? If so, it's likely a simple fix, eg a single broken wire. Keys are usually wired on a grid array eg 25 columns x 3 rows.Pressing a key eg connects the 17th column to the 2nd row so the device knows which key it was. So if there is a broken wire to one of the rows, 1/3 of the keys will suddenly stop working.

HI, Your unit is very old and it can be repaired. Look for someone who does vintage synthesizer repair. John, Syntronics.

I lost my adapter to my keyboard and I need to find either a substitute or a new way to turn it on without the adapter, HELP!!!.


Some Casio Keyboards use 9V DC (center negative) others 12V DC (center negative).
If check what voltage your Keyboard use. Generic AC adapters are usually center positive. So you have to invert the wire with a new DC plug to make it center negative,
Easiest is to buy a Casio ac adapter made for your keyboard from a Casio retailer.

My Korg c15s has a lot of grating staticky noises when played ....I'm told it cannot be repaired as Korg no longer makes parts for this model?


I have a Korg C-15s and also experiencing loud crackling sounds when I turn it on. The problems seems to be either the sliding volume control or the amplifier itself. Honestly though, I believe the issue is the volume control. I opened my piano to get a closer look and attempted to clean the contacts on the volume. Unfortunately after cleaning the contacts, the crackling sounds became somewhat worse. After I turn the piano on, the volume control is generally rendered useless......volume set to low volume and the noise is quite loud and other times the volume control is set high and get very low volume crackling noise. No real consistency. The noise does diminish after a few minutes but so does the piano sounds to an inaudible level. There were a couple of instances where I turned it on and surprising enough, no no noise and perfect sound. For these reasons I believe the issue is within the volume control and not so much the amplifier. I have an electronics background and noticed that the volume control is very unique in design and is not something that can be substituted with another volume control from other sources.

My recommendation is to check the sound quality of the audio from the RCA L/R audio outs on rear of the piano by connecting to a stereo receiver. If it sounds fine you're in luck. If the crackling sound does not diminish after a few minutes like mine does, I would suggest disconnecting the internal speakers and using the audio out only. You can connect a pair of studio monitors or high quality computer speakers, preferably with a small subwoofer to deliver the full audio range and deeper tone of a real piano. I'm currently using a basic pair of Logitech computer speakers and is quite acceptable until I can afford a high quality set of monitors or relocate my piano closer to my high quality Yamaha receiver.

I hope this info helps a bit.

Casiotone MT-220 keyboard power cord


I would inspect the unit for corrosion on battery terminals AND the power connector. The connector has a switch when a cord is plugged in, and if this switch doesn't work (they get bent) the unit will not work on batteries.
Best source of power adapters is often your local thrift store.
MATCH the voltage and whether it is AC or DC required AND the polarity if the pin is + or -.
Get one with enough current.
