Sorry to hear. It is repairable, but that does take time and money. If you're like most ppl, the biggest issue is the time and hassle for such a repair. Some manufacturers (dunno about Keystone, though) will, for a price, let you bring in a rig to the factory to fix such things but it's on their schedule and they may not have the wall covering to do an exact match for older units.
Think of this, though, it just means that there's a rig out there somewhere that you'll like even better
