Hi Guy's i've been running my s4 for over a year now, have had a few problems  nothing i could not get my head round, last week a fuse tripped in the house but only the side with the router connected to, so all the miners started beeping away. I was at work so the wife turned all them of so they could grab an IP address but the s4  does not work only a steady red light and flashing amber light and it clicks. So i bought a new PSU of a company it does not tell if it's new few scratches on the new psu. But fitted that psu got the same problem, do you know if the Ethernet connection  point could cause the fault or do you think the company has sold me a dud PSU. Thanks in advance.
