Mack, just call Apple tech support. Since you're beyond the 90-day free support period, they may ask for a credit card up front in case the problem is one of software, not a hardware fault, but if the problem is one that is covered by warranty, you will not be charged. Apple will send you a box to send your iPad it to them for replacement.
Alternatively, you can go through Apple's online service assistant to request service:
