Nexus Player restarts after 10 seconds. Was working, started restarting from time to time, now its not working at all. TV screen says no signal (if you unplug the hdmi cable it says "check signal cable") If you connect it to a PC you hear the USB connect/disconnected chime every 10 seconds (give or take) and it appears and disappears in device manager. Any ideas whats wrong or how to fix it? Thank you.
