Hello, at first we'd removed the screen and connect it again ( to avoid of a human factor) if all is fine, try to connect a new one (the check of malfunction the screen). The both are the easiest approaches for analyzing of this fault.

Hello, I will try to heat it with a hair dryer but how do i know when the surface of the phone hits 70C?

We don't have things for temperature measurement too. Usually we heat the surface (30sec-1min) and after that trying to open carefully. If the glue still strong you have to heat the surface anew and carefully!
