Hello friends!

I have the following problem. A few days ago I connected a midi interface to the keyboard and it seems to defuse the midi of the keys D, F # and A #, and now I do not know how to repair it. I think the keys are not dead because it was just when I connect this interface, but I do not know how to make them sound again. this problem is in all octaves dem keyboard. Does anyone know how I can repair it? thank you!

If the symptom is that D/Gb/Bb are not working in all octaves, the cause might be a disconnected line in the keyboard array-scanning.
It could be caused by a broken trace on the circuit board (not likely) or by an unseated connector.

If you're keen to open up the piano and have a look ...I'd try disconnecting the cable(s) that join the keyboard to the electronics, and re-seating them.

If not you'll need to find a local Kawai-trained technician. The Kawai web site can help with that.

Is there an option to RESET keyboard to factory specs ?

I would try that.

the user manual says that each time the keyboard is turned on, it restarts, then they do not include a factory reset for this reason. This problem has driven me crazy. I hope a Christmas miracle frown

In that case, MacMacMac may be right and you may need to get out the tool box.

Hey Guys! The Miracle of christmas Happened! I do not understand what happened, but two days ago I turned it on, and the keys rang intermittently. Here I recorded a video to see how it behaves. this reaction is totally random, because I did nothing but turn it on and play.

Definitely get in touch with Kawai to have a technician look at it - that's not normal!

Some part of the circuit is loose... if it is out of warranty, open it and have a look!
