Antminer S5 stopped working, won't connect/reset

[hansgruber]

So bit of a weird story.

I got an Antminer S5, factory reset it, connected it to a gold 605W PSU and pool and was mining at 350 hz, 1150 GHz and everything was working for around 12 hours at 60 degrees. Before I shut it down I changed the hz to 150 to see if it quieted the fan and shut it down.

I bought a new fan, removed the stock fan and tried to connect the 120mm new fan. The 4 pic connector was slightly different on the back and it wouldn’t fit the plug. I put the stock fan back on and powered up the machine.

Since then the only lights on the miner are 3 green and 1 red on the control board. There are no lights on the blades and I can’t connect to the IP anymore. The 2 lights in the Ethernet cable are on but not the green or red lights on the right of the Ethernet.

I have tried everything to connect, it won’t factory reset and nothing I do changes the power up sequence. The fan turns on and there are just the 1 red light and 3 green lights in a row on the control board. The Ethernet cable is connected and it works on other computers. I can see everything connected to my router but the antminer has disappeared. It seems like it is not powering up at all.

Please help.

 You changed the hz or the MHz ?
 I think you made confusion with the units
 Mining at 1150 GHz it's impossible

I changed from the standard 350 to 150. The fan slowed down considerably. I'm kind of lost, as there is no way to access the miner or reset it, it seems like a lost cause.

Humm
I think you are not reseting it well

Hi there,

Did you sort this out? I'm having a similar issue. Could it have been a power network issue? I'm in Canada so it shouldn't be a problem, but I am in an apartment building and thought that may cause issues.
Anything else you tried it would be good to know
