I have a major problem and need troubleshooting help! Today all 3 of my 1TH/s miners stopped working.  One stopped working after mining non-stop for a couple of weeks (it was left alone and untouched) so it couldn't of been hit at all. I turned it off and back on, nothing. I ordered a total of 3 from batch one and today all 3 stopped working after i turned them off and back on! all i did was power down and turn them back on & the screen just displays a dark blue square, a red light & the fans always run full blast, I cant even see them on my network. I find it strange that all 3 decided to kick the bucket on the same day. Should I RMA all 3 i'm not sure what to do.
