Chosen Solution

I recently did some simple repairs on my iPhone, was careful to not displace any components when disassembling and reassembling, but the power button no longer works. I have been told I need to replace the Power and Sensor Cable. I am simply shocked that I have run into this problem after being so meticulous. Has anyone else seen this sort of thing happen? What causes the cable to go? Thanks a lot fellow fixers.

You broke it. Gotta put in a new one
