I actually did repair this board instead of replacing it. The component that failed was a 10ohm 1 watt resistor available at Radio Shack. Removed the old one, installed the new one and it works just fine now. This board was from a basic range so there was only one logic chip and no surface mount components so it's relatively easy to repair. Most of the boards anymore are getting to complex to repair with readily available parts. But if you are in the middle of nowhere, it may be time to get creative as a tech.
