The resistor he's speaking of, is the one behind the battery. If it has actually gone south, it is replacable with (I believe) a resistor from the legacy.

Someone here, or maybe on Yahoo has stated that you can go to Radio Shack, get a resistor with the same value, and with a little soldering replace a bad one for just a few dollars. I spent around $90 for mine from a local dealer.
