Did you tryed the hard-reset? Remove one of the rubber foot on calculator's back (I don't remember which one). There will be a small hole. Insert a clip inside it until the calculator resets.
I hope this could help.

The reset might fix it but I doubt it. It could be under either the right or left upper rubber foot - it changed sides during the SX's lifetime so you've got a 50-50 chance.
If it does not recover with either the YES or NO choice, you have a contaminated or otherwise shorted keyboard. You might be able to clear it out by cleaning with an ultrasonic cleaner but it is likely to return. As the SX is at the bottom end of vintage HP values, it might be wise to pick up a used replacement. The 48G is less costly if you don't need the expansion ports.
