My phone screen goes off by itself and it stays off and comes back on its own ....i changed the screen and the batteries but I'm still facing the same issue... Please any suggestion

Try flood-cleaning the Power button with alcohol. Any difference?

Welcome to Android Central! Which phone? There might be a problem with the connection or the motherboard. It can be very difficult to help you troubleshoot since you did the repair yourself. You may want to bring it to a qualified repair shop.
