Hi guys,

You know what, I had a similar problem and I tried it all.

Reset button, power down for an hour, individual testing if hash boards. Did it all. When I contacted bitmain they just quoted the user manual. What a croc of shite!

Anyhow to cut this short I found my problem.

Disconnect all your power and hash cables.

Pull out your control board.

Flip it over and I found serious solder oxidisation.

My miner is in a controlled environment so no moisture or anything.

The oxidisation creates artificial paths between points which causes the machine to go WTF!!

To fix get a NEW very dry toothbrush and brush out any oxidisation.  Chuck your board back in and boot her up.

Mine ran like a dream.

Hope this helps guys.

Ill take a small BC OR BCC doni if your machine starts up.

Ok so lets see.

What have you tried so far as to trouble shooting?

 

Well also might be good to check your network setup.  Diasable your network adapter or reset it.  I had issues with mine when I relocated my machine.

For some reason it finds a new IP for the unit. Mine decided to add a number from XXX.XXX.X.105 to XXX.XXX.X.106.

We will work this out buddy. I tore hair out for 6 hours.
