Sustain pedal does not work on brand new Suzuki mini grand digital piano..... who fixes it

It sounds like you may be experiencing issues with the sustain pedal on your Casio CDP-100 digital piano. The problem may not be with the pedal itself, but with the internal connections or circuitry of the piano.
If you're unable to factory reset the piano and it's not responding to the sustain pedal, it's likely that there is a problem with the main board. This is a complex issue that may require professional repair.
However, before giving up on it, you can try the following steps:

1. Check the connections: Make sure that all of the connections between the pedal, the piano, and the power supply are secure and that there is no damage to the cables.
2. Check the power supply: Make sure that the power supply is working properly and that the piano is receiving power.
3. Try to update the firmware: Check if there is a firmware update available for your piano on the Casio website. Updating the firmware may fix the problem.
4. Check the manual: Consult the piano's manual for troubleshooting steps, it may have some information that can help you.

If none of these steps work, it is likely that the problem is with the main board and it will need to be repaired by a professional technician. Unfortunately, this can be an expensive repair. Keep in mind that attempting to repair a digital piano can be dangerous if you're not familiar with the proper procedures and safety precautions.
It's important to keep in mind that the piano was second hand and you were aware of a problem with it and you have been given a lower price as a result. It is also important to note that buying second hand musical instruments may have hidden issues, which is why it's always advisable to inspect it thoroughly before buying it or to buy from a reputable seller who can give you a warranty.

To start with always best to use the correct power supply these should be readily available from any good Yamaha store. Is the sustain pedal a Yamaha pedal? The plug end of the pedal connect a multimeter across the two connectors and set meter to show continuity. If there is no continuity press pedal, hopefully this will now respond. If not then the break is in the pedal. If meter idea works then it could be the socket on the keyboard, these can work loose on the pcb they are mounted to if they are used a lot.

You could open up the keyboard and look inside checking the solder joints on the socket or simply take to a Yamaha service centre.

You could also try a master reset of the keyboard, hold down the highest note whilst turning on, this will reset to factory default.

Let me know how you get on.

The Casio Privia 410r has two pedal jacks at the back. One is the sustain pedal, the other is the soft/sus jack. Please use the other jack if you want to use sustain pedal. Only 1 of the 2 jacks can be used.


However, if you have the optional sp30a pedal which plugs UNDER the piano instead, then only can you have 3 different piano pedals.

Odds are it needs replacing or a technician. Contact a local music store that sells Yamaha pianos or call Yamaha at 714-522-9000.

The first question is has it ever worked? If this is new, the connector of the pedals is a mini DIN type which is REAL hard to get seated properly. Often something blocks it from seating fully. Remove the plug and with a bright light inspect the pins... they are EASILY broken off. Aligning the connector carefully and making sure it seats is important. This piano also has a foot under the pedals to screw down against the floor but that isn't wht cause the pedals to not work.

I assume you are plugging this into a ROLAND brand product as the Roland sustain uses a normally CLOSED contact while MOST other brands use NORMALLY OPEN contacts.

The Roland synths now monitor the pedal as the power is turned on and supposedly decides which contact type is used.

Remember that for MANY voices, such as piano, notes are held longer BUT they do not continue indefinitely just like the sustain on a real piano works. On a real piano the dampers are lifted, but the strings eventually stop ringing due to the losses of energy in the strings.

Some voices will be held,such as organ tones.

I don't have enough information from your post regarding what voice you are having trouble with.

The contacts of various switches and keys are likely dirty. They are often conductive rubber and need cleaning with 99% isoprophly alcohol and q-tip. Clean both the conductive rubber pill and th circuit board traces they contact.
