Hello zitpit and welcome to the forum. You have not provided enough information to answer your question.

Do you mean a Suzuki HG-425e digital grand piano? If so then the problem may be with the power supply or with a bad circuit board, you'll likely need to have an electronic technician look at it.

There is not a lot if information available to non owners on the Suzuki HG-425e. You may be able to get a better response from a keyboard forum.
