Thank you for your question, my name is ***** ***** I look forward to assisting you.
Please note, a rating is only needed when we are finished.
Can you please remove the power to the piano (so unplug it from the power socket).
Then wait 10 minutes, connect the power again to the unit, turn it on and tell me please if it is now operating correctly.
Let me know the results please
It is the internal powerboard that has faulted. This will have been caused by a power surge or disruption on the line.
I am really sorry about this and you are going to have to return the unit to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you. I would also advise you invest in a surge protector like this to avoid losing your electrical equipment to these surges
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
