Replacement screen wont light up when mid frame is fitted
I recently replaced a cracked screen in a friends Galaxy S4. When I first put the phone back together I thought the new screen was faulty as the phone would turn on but the display wouldn't light up. After some fiddling around I tried turning on the phone while I had the mid frame removed and to my surprise the screen worked just fine. Upon re-installing the mid frame the screen stopped working again. I removed the mid frame once more, turned the phone on and then began to snap the display assembly back into the mid frame. Everything was fine until I snapped the display assembly and the mid frame together around the top left corner near the volume button at which point the screen cut out. Does anybody know of a way that the screen could be shorting out? Or could it perhaps be pressure on the digitizer flex cable? Any assistance would be greatly appreciated.
