iPhone 5 won't turn on after replacing camera

[domdud]

Hello.

Ahead sorry for my English.

Last week I was replacing my back camera cause I had pretty bad floaters when I was shooting some photos. I did it by one tutorial on youtube.
When I put together my iPhone I could not turn it on.
The power button doesn't work.
I plug it into my computer and it turned on.
Okay, I thought something bad with power button or flex cable.
Today I replace flex and button and still won't turn on.

Is any chance I broked something in mainboard? I don't understand why the power button doesn't work.

Thank you very much! I am frustrated of it.

The only thing I can think of is trying putting in the old camera, and see if it begins working after doing that.

Or you could try disassembling the camera again, and reassembling, since you might've left a screw loose or something.

And is any chance that motherboard is broken?
Or it is very small probability?

I will try it
