-Does the light ever pause even for a second?
Please give me this information and I will be happy to assist you further.
Yes, I suspect the formatter actually, I need you to unplug the large connector on top of the formatter board and then plug the set in and see if the light stops blinking. If you do not know what one the formatter is...it will be easiest if you can take a picture of the boards there on the left side and I can circle the connector I need you to unplug.
