Do you have the latest firmware (2013 11 25 (5447)) on your Prime ? Have you tried a hard reset using the pinhole at the rear of the calculator ?

Yes, I do have the latest firmware. I was looking how to flash the memory and put the latest firmware again and accidentally I fixed the problem by pressing together the:
On+Apps+Esc for very short time and releasing them together. It seams to be working OK for now and I hope it stays like that.
Thanks Michael.
