Yamaha CVP 609 Keyboard not working

I have a CVP 609 but I the keys won’t make any sound. It says Internal Hardware Error. If I leave it unplugged for a while it will turn on and I can play a song off the piano so the speakers work but the keyboard still doesn’t make any sound. I was playing it when it stopped working the keys just stopped making any sound and the display said “internal hardware error”. Any ideas? Is there a fuse that blew somewhere or is the keyboards mother board damaged. Please help

If it's anything like my old Yamaha keyboard they are notorious for having bad connection problems in the circuit. So take off the top so you can see all the wiring inside. Mine has many wiring ribbons which have soldered wires going into a connectors. Take out every connection one by one by gently prising the plastic clip up and spray each connector and ribbon wires with an electrical contact aerosol spray This drys in seconds then carefully push the ribbon wires back into the connectors. Plug in and try.... No harm done if it doesn't work... but mine has been magic since. good luck

by: YKG

Based on the symptoms you described, it is possible that there is a hardware issue with your Yamaha CVP 609 digital piano.

When the display shows an "Internal Hardware Error" message and the keys don't make any sound, it indicates that there may be a problem with the internal circuitry. Leaving it unplugged for a while may help reset the system, but if the issue persists, it may require further investigation and repairs.

It is unlikely that a blown fuse is causing this issue, as a blown fuse would generally result in a complete loss of power. It is more likely that there is a problem with the motherboard or another component of the keyboard's internal electronics.

To troubleshoot this issue, I would recommend contacting Yamaha customer support or a certified Yamaha service technician. They will be able to provide you with more specific information and help diagnose the problem. Depending on the severity of the issue, it may be possible to repair the keyboard, or you may need to consider replacing it.

In the meantime, avoid using the keyboard until the issue is resolved to prevent any further damage.
