circuit board

IF the pot checks out ok and you suspect the circuit board, before buying one consider repairing it. Problems are sometimes obvious and simple to fix. You can often see where "the smoke came out" of some component or where there is a broken wire or bad conductivity at a soldered connection. I can't remember how many things I've fixed over the years by simply remelting "cold" solder joints - one day it was air conditioners on two separate family vehicles. (The hard part is finding the problem point!)

If lacking experience in testing and repair locating a friendly local electronics geek might result in a cheap or free fix, just for fun. Besides the Makers club mentioned, school teachers are a good source of referrals, especially those who work with robotics competition.
