Even after signing-up with a Yahoo/Flickr account I can't see these photos as it says they're private.Here are some pics we took before swapping the modules.
Is the controller a Mainpine EPC, a ZeroCarbonWorld EPC, or a Rolec unit?
If it's a Mainpine EPC then if the LED is not lit then it should mean that there is no power going to the device at that time. However, you've confirmed that there was power, and so if it is a Mainpine EPC it would seem to be defective. However, you've replaced it, and the behaviour is the same, so I'm thinking that it's not a Mainpine EPC.
