Screen don't turn on

[Bruno Moreira BM]

Hello, I'm have a problem with my Galaxy S5 (SM-G900M).
When I turn on my cell phone It works perfectly, but when the screen turn off by pushing Power button or waiting a little time, the screen don't turn on back when I click on power button. The touch is working, and I can use the cell phone without see what I'm doing. It just the screen don't turn on until I Power off the phone (hardly because I have to click in Turn Off and confirm without see) or take off the battery.
Any idea about what I can do to fix?
Thanks!

Welcome to Android Central! Try booting into Safe Mode, which temporarily disables all 3rd party apps. https://support.t-mobile.com/docs/DOC-10696

If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.
