Communication has been slow, and the product has unfortunately failed. It has turned out to be a costly error to buy from this seller. My machine has a malfunctioning touchscreen cable, which cannot simply be replaced. Initially, they suspected a connection issue with the controller. I purchased that, but after consulting outside help, I found that the controller is functioning properly, while the cable from the touchscreen to the controller is unable to transmit data. The repair costs $100, which seems excessive!
