The unit runs on a 12vdc adapter. Check the output of your adapter with a meter and verify the voltage marked on it.

There is probably a SMT fuse on the board near the plug. It should be labeled "F1" unless there is more than one fuse. You could check to see if that is blown and replace it. Set the meter to OHMS and touch a probe to either side of the device. A good fuse will show 0 ohms.

You could check to see if that is blown and replace it if you have a solder iron. Set the meter to OHMS and touch a probe to either side of the device. A good fuse will show 0 ohms.
