I have a Yamaha p140, and several of the notes have gone out of tune! Aflat and e-flat are now out by nearly a quarter pitch. I didn't think this was possible.
We do have a child who like to push buttons on the keyboard; is it possible he managed to "de-tune" the intervals some how? Is it possible to re-set the tuning?
turn off your keyboard and turn it on again while pressing c7 (last key on your piano)
Same problem happened and that fixed it

Technics SX-PX662 also out of tune by: Rob
... and turning off and then on holding down highest key on the keyboard didn't make a difference. The piano's in tune with itself, but the whole thing is about half a tone sharp. Much obliged for any help folks can give me.
