Disconnection, motors disabled

A few days after getting the machine the controller quit powering up. It started displaying disconnected after attempting to home so I restarted it and the monitor. Started it back up and got a disconnected popup. So I shut it down again unplugged it and flipped the switch before plugging it back in. Now I just get silence from it after flipping the switch. Checked the E stop and other connections, blew everything off and checked the fuse. All good. The green light luminates and I checked everything I could. Then flashed the sd card with nothing but silence still. 1F sent me a new controller and I received it today but now I have a new issue with it saying disconnected and not moving with a controller. Its displaying an orange triangle with an exclamation mark. I hit reset on the config settings. All the motors show disabled. Any ideas?
