keith harris, usually when the touch screen does not work in a specific area, it is the digitizer that has failed. Of course you should always try a reset/ recover on your device first, if it is unsuccessful you will have to replace the front display assembly. Follow [guide|7277|this guide] for that, and the part is available [product|IF115-000|right here] as well as many other places. There are those that say you can separate the digitizer from the LCD, I personally have not had any success with it due to the lack of proper (expensive ) equipment for that task. Hope this helps, good luck.
