Replace back cover on xperia z3 now power button won't work

Hi, This morning I tried to replace the back cover of my xperia z3, because the glass was broken.. So everything was going great until I attached new back cover back on. Now the power button don't work, it's like nothing really happen, I tried holding the power button and volume up, nothing. I tried pushing the yellow button next to the sim card, nothing. But when I plug it into the USB or electricity it starts to charge normally, LED light goes on on on the screen I see % of the battery life. Do you have any idea what should go wrong with it?? But one strange thing happend while I was cleaning the glass from the battery, the phone just turned on, so I pushed the power button to turn it off and then continue to clean the glass and attached new cover. From there on the power button don't work at all.. I tried booting my device through Flashboot but I can't seem to get it to connect, probably volume up button don't work either.

Oh and one thing.. I didn't touch any of the flat cables or unplug them.. Only the one for battery

Has anyone have any idea how I can turn on the phone without the power button??

the yellow button near SIM works if the phone is plugged and charging.. but all it does is only vibrate and turn off and then charge again

It is not advisable to perform self repair of your device unless you are a professional technician. As this is more of a hardware problem, i suggest that you contact your local service center

I always repaired all of my Phones before, so I wasn't trying something New.. Back cover went off pretty easily so I'm sure I didnt damaged something. I got my Phone to Turn on, luckily my volume buttons still works so I manage to fastboot it. But the Power button still don't work, my Phone is still in warrancy But I Don't know if I can Use it now that I removed and change back cover. I could try.. All that I can find on Google is that Power button not working is a common problem for z3..

I do Think it's a bit odd that the flex cable is not visibly damaged and I didn't even touch it.. And if it were damaged its odd that only Power button won't work everything else works fine.. Main flex includes antenna, vibrating motor, main microphone, power button, volume buttons and charging port contacts But this is working okay.
