Unresponsive Asus touchscreen


May 16, 2013
I have an Asus tf101 tablet and on an OTA update the tablet's "touch" functions seems to be malfunctioning. In other words I cannot activate the "start" button via touch when the asus tablet starts up and the Android welcome screen appears. I can adjust the volume and I can reboot the machine however using the volume and power buttons. Research on google has shown the below techniques none of which seemed to have worked:-

I tried wiping the device
resetting the device to factory settings
flashing the device using EasyFlasher
updating the firmware
draining the batter life

And I am still not able to get any touch functions working
Could this be a hardware problem?(my warrenty is up)
Or is this a software problem?

What can I do to fix this?
