Do you have an idea as to how it was damaged? Just curious...
I recently had a probe go bad as well, with the same symptoms. I found the male plug was bad. So I cut it off, stripped the wires--a delicate job--and then attached them to a new male plug. You have to make sure to attach the wires to the appropriate connections (e.g. ground to ground, etc.), but some online diagrams help. And then of course, you have to be able to solder. But the new plug works--for about $3.00 in parts. The end is wrapped in a lot of electrical tape, so it's not pretty.
