Black screen after boot

[Guigo]

My xperia z3+ just updated itself last night to Android Nougat, but now every time I turn it on after the Android logo the screen auto turn off and no matter what I do it just wont turn the screen on again, tryed everything, hard reset, companion repair and nothing seems to turn the screen on, the only way to turn the smartphone off again its the combo power button + volume up. Then I can turn the smartphone on again, but the problem persists, after the android logo, the screen auto turns off and dont turn on again. Anyone with tha same issue? How to fix it? Sorry for my bad english
