Hello,
I have a brand new AP-470 which I purchased 3 weeks ago. worked perfect and we all love it.
However, a few days ago a problem came up:
1. we are unable to turn off the piano.
2. we have disconnect the power and wait 15+ minutes before turning it back on. if we turn it on before that the lights in the panel light up but no sound comes out.
3. if we wait the time and plug the power back we can turn on the piano, it works for 2-3 minutes and then sound is gone and everything stuck again.
I tried reset the piano per the user manual instructions and no luck, also removed the USB cable etc... nothing works.
Any advise?
Thank you.
