I don't know about electronics specifically and different country issues (I live in Ukraine), but in general store if you would accidentally* break anything then, regardless of store rules, the store can't require customer to pay for it. *I don't exactly remember about "accidental" part. I suppose that store would be required to prove that action was intentional in court.
