"Most likely the detector is the bad part and not the LED (unless someone
plugged it in backwards)."
Doesn't Radio Shack sell a little piece of translucent stuff that
shifts the IR into the visible spectrum so you can see it? I seem
to remember a friend of mine that does a lot of IR work having one..
That would be one way to tell if it was a bad LED
