If overloading the power supply is the problem, wouldn't that shut the unit off completely? When this happened the screen was still on and scrolling.
My other question is if there is anything I can try or should I call for service. If I do, can a tech figure out if that is the issue easily?
I am living in a rural area, so it might take a while to get service. The piano was brought brand new and is still under warranty.
Thanks again for your reply.
