Power Button not functional

Hello, after a display replacement on my Sony Xperia Z3 the power button is not functional. When I connect it to my notebook it starts charging the battery. So I replaced the main flex, but it doesn't worked. Same problem when I rebuild the old lcd.

Is this a good question?

Yes. But I'm sure that the logic board is not the problem. If I connect the Xperia to my computer it shows the charging symbol. If I disconnect the main flex nothing works, even if I connect it to my computer. So I think the connector on the logic board should be functional.
