Answer to: Entire touch screen totally unresponsive on right side of phone.I seen comments about there being lines on the screen. some one said it was leaking and need to be replace. NOT TRUE! I found an iPhone 5s on a bus bench and the screen was unresponsive, with white lines running vertically .I disassembled the iPhone 5s after getting to the bracket that hid the flex cables I detached them all cleaned them with denatured alcohol and put them back together. The screen worked perfectly. I was then able to return the phone to its proper owner.
