Help with a Dead S1

[bgibso01]

I've got a week old S1 that has decided it doesn't want to turn on.  I've tried various psu.  They all kick off as soon as power is thrown.  I'm guessing there's a short?  Has anyone seen this issue and is there a resolution short of sending it back?

Thanks,
B.

I would try attaching a PC fan to the 5v molex line or connecting a hard drive/cd-rom drive to the psu.

Some power supplies need you to run something on the 5v power line before they will run right.

I had a similar problem, miner would run for a couple of minutes, then trigger the PSU safety off.

I'll give it a shot, but I'm using the corsair TX850 and CX500.  Neither ones have given issues with other units.

try only powering the side with the ethernet  so only use 1 pcie hook up and pull the white ribbon that links to the second board.

If that works.  do the same with the ribbon attached. if that works then the board with no control card is the issue.

Thanks for the response.  So far it looks like the LAN card side power is the problem.  I can plug in the other blade and it doesn't blow the psu off.  But as soon as I would plug into the LAN side, it shuts off the power.  I never even get a LAN light, just instant trip.  At this point, I'm thinking I now have something to rob parts off of in the future.

try fully moving the lan/controller from the one board to the other.  it can be done.  if you are lucky you will have 1/2 a miner.

Yep.  Tried it this morning and now hashing at 1/2 speed.  I've received a response from Bitmain wanting me to narrow down the issue.  Pretty sure we've narrowed it down to a bad board.  I'll keep everyone posted here as to how well my warranty experience works with them.

Good I  am glad I helped and you know the old saying ½ a loaf is better then none.
Hopefully they send out a board asap.  Let us know.

So here's the latest. Yanhua Qin has been corresponding via email with me.  Has offered to send board now for a .51btc deposit until they receive the bad board back.  Not quite what I'd say is reasonable, but it is at least an offered solution.

I've requested the RMA address and I think I'll just send the board back first as I've got other miners coming in Monday.  This is all assuming shipping doesn't cost more than it'd be worth to have a new board or just purchase a new miner.

I'll keep everyone posted.

Have you tried ATX power supply? Maybe fans should check if the boot when the fan is not working, it will refuse to start.

One board works the other is shorted.  the psu works on all of his other ants.  the psu works on one board but not the other.
