Were you replacing any of the drives? The single bay My Cloud, the subject of this subforum (My Cloud), is a completely different device and doesn’t have a front display screen like the EX4 has. And the LED lights on the My Cloud may indicate something different than those on the EX4.
There is this discussion (if you haven’t seen it already) in the EX4 subforum that might have additional information that may be relevant to your issue.
There are also a number of other discussions that may have information in the EX4 subforum. One can, if they haven’t already, find them using the forum search feature (magnifying glass icon upper right).
