Hi thanks so much for that.
This isn't a display issues even though it appears a such.
The problem is more than likely the main power supply section of the piano has a problem and no longer supplying the correct current the unit needs internally.
This is not likely an expensive repair but it doesn't require testing by a skilled technician to determine the exact component failure and replace that part.
I wish I had better news for you but its a good thing the display is likely ok as that would have been an expensive part to replace.
The power supply is much cheaper even if they replaced the entire board which I doubt they will do.
Sear may take this in for repair Also BEst Buy as well;-)
