I don't like to mess around with a potentially bogus receiver. I replaced one earlier this year when I thought I could transfer a receiver from a crashed plane into the new plane. It wasn't working, so rather than try to send it off for repair, I "garbaged canned" it, and bought a new one. Why mess around with a potential problem, the new plane should have the best insurance I can give it. Too many other things to go wrong, like my thumbs.
