Hi

My Ipad 4 touch screen is unresponsive(already reset,restart etc). Went to other service center and got it fixed but in few days the screen is unresponsive again so I went back
and in 1 week they give up, telling me that they replaced the sensor chip few times already and within few hours/days the chip got burn again. So I got full refund.

Can you fix my Ipad 4 problem ? How about warranty ? Or my Ipad 4 is basically just paper weight ?
Will I get full refund if you guys tried to fix my Ipad but it still got problem later on ?

Please help
