Hello, i just installed 3 deco x60 v1. One of the three keeps shutting off. I get solid green light and it works for some minutes then goes offline and the green light starts to blink very faded. I tested other power supply but the problem stills remain. But it feels like a power supply problem because if a wiggle the power cable it can start sometimes but do the same after some minutes. Any solution? 
 

sorry bad english. Im from sweden.
