Iphone 4s touch not working

Hi friend, Ihave a problem with touch screen of my iphone 4s. Suddenly after a charge touch screen not working, all the rest work perfect.

I try to replace it with several touch+lcd, but it isn't the problem. So i follow the solution of tesla in picture but:









- touch connector is perfect

- resistor around pmic is ok

- I replace touch ic with a new ic





The problem is the same!

I'm going crazy, please help me..
