Dude,
There are reports that the module could work with some of sub modules removed. If the whole module is cold it probably means that there is a problem with power cable. If i remember the cable was damaged according to your pictures. Take a multimeter and make sure that power power cable is ok. The second thing to check is to disassemble the module and see if hash power PCB is damaged (the board with connectors where asic are plugged). If above two are ok, you can test all 6 modules separately this is presumption.
About the warranty that shall be commented by Avalon but i think it shall be replaced and it will take time for sure.
If all of the above fails we badly need 10 Asics for Klondike project
https://bitcointalksearch.org/topic/klondike-16-chip-asic-open-source-board-preliminary-190731 and we would be more than happy to buy part or whole 8 x 10 Asic chips.
PM me if interested
Did you see the STATE it arrived in though? You should definitely be offered a replacement, shipping you a used product that is 1/3 DOA. Think about it of course you're eligible for a repair!
It may be damage to the ribbon cable.
Go to cgminer api log tab and post this info copy paste here and we can tell what module may be down.
This is the log after 12 hours of operation at 300 speed setting.
