I own a pair of C40's as well, Once they are working you will love the sound! I would double check the connections again, and look closer at the crossover for signs of issues there. I don't think there is a fuse in these, but I could be mistaken, I didn't poke around inside too much yet.
If the tweeters are peeling, and muffled like mine were, Parts-express has a truncated silk dome tweeter that are practically drop in replacements and sound fantastic.

Realistic fan.
Could be a bad connection. Check both ends.

I have this identical problem. Looked at connections. Tried using the speaker wire from the other speaker, Opened up speaker and looked at the crossover. Looks good no visible issues. All wires plugged in and no loose connections inside. I am assuming crossover is fried.
It is possible that all the drivers are fried, but that seems unlikely - one maybe, but not all. Test the drivers individually by putting a meter directly across the terminals of each driver (not the main connectors on the back of the cabinet) and check for resistance of about 6 or 7 ohms. If they measure ok the voice coil is intact. Then try touching the contacts of a 9V or 1.5V battery across the terminals of the bass drivers and the cones should pop outwards or inwards depending on which way round you have the polarity. If they do, they're good. I don't think I'd feel safe about doing the same with the tweeter, but you'll find out later if that's ok.
If the drivers are ok you can assume the fault is in the crossover and concentrate your efforts on that.
