Electrical-sat controller and bed inflate-no power

Does the Satellite control box light up when you push the on button? If not that would indicate it does not have power going to it which may indicate no power to the outlet(as mentioned with the inverter), a loose primary plug in to the 120 volt outlet, a loose plug in to the back of the black 120 volt to 12 volt power supply, or a loose plug from the power supply box in to the back of the control box.
