If you have no power to the switch, the problem isn't the switch (as was suggested) but rather no power from whatever FEEDS the switch. (as was also suggested)
On most of these units that operate via a switch and a remote, there is usually a bank of relays somewhere (usually hidden) that control the separate current feed to both the remote and the switch.
If you have a multimeter and know how to use it, you can do some simple troubleshooting tests on those relays and trace the source of current throughout the circuitry.
