Best suggestion would be to open the controller up and inspect for any corrosion or water damage. From the sounds of it, this is probably the case. If inspection doesn't come up with any leads then the only other suggestion I could make is replacing it with a used one off eBay. They're very cheap now and it's the most economical move to save time and/or money. Good luck.
