Summary: I have one of these and the display began to fail after only 4 months. My friend has the same range and his display had similar problems as well. I researched the issue and it turns out that these touch screens fail quite often. Luckily mine failed while it was still under warranty. The part costs $171.00. I am not sure how much it will cost to have a "certified technician" replace it but i bet it will be at least $150.
