What rig do you have?
That’s s a Schwintek. There is no manual crank. You can disengage the motors and push the slide in but you’ll need some helpers just for muscle power.
Edit: looks like slim rack system. Just turned daylight here and looked at mine.
First tell us more about the failure. You said TV side not running, so is that the front side motor not running at all? Did the slide start to move and stop?
If nothing is moving or trying to move, then of course the breakers come first. Those are usually the 20 amp auto-resetting on the bottom row on your panel.
After that we find the digital controller and try to override it
