First of all, if she has saved any Registration setups, recorded any User Songs, or transferred any style files or song files to the keyboard's internal memory, then she should connect the keyboard to a computer or iPad and save the Backup File to the computer or iPad, so she doesn't lose them.

After she has backed up anything that she wants to keep, she can do a factory reset by following the steps for a "Backup Clear" and a "Flash Clear," as described on page 56 of the PSR-E403/YPT-400 Owner's Manual in the section about "Initialization." This may or may not fix the problem, but it's a good place to start.
