I was having a problem with my Coocase. The alarm, lights, open-close feature would only work if I pushed down on the lid. I removed the case and popped out the connector assembly on the bottom of the case. I found that two of the three connectors were no longer soldered to their respective brass connectors--just barely touching the connectors. I soldered the wires back to the connectors, and now all functions have returned. I thought if you notice your Coocase lights, alarms, or other features not working, you might want to check the connectors on the bottom of the case.
