I have a problem. And although my Ps4 does not work properly after a hard drive change, my ps4 no longer works. It no longer connects to the monitor, it no longer connects to my controller. I need help urgently!

Is everything connected correctly? Possibly reconnect the monitor?

In order to reinstall the software, the controller must be connected to the Playstation with a cable.
