Do you have any  experience with  warranty claim   for bitmain.com   /error miner S3+/?
I have fail miner S3+. Its have only 220GHs speed.not working second hash board...

Back in batch 2 of the s1 units I had a defunct board with the fault appearing to be the dc regulator. They organised an RMA for me without much issue.

Does the second board just not show up? Open up the case and check for any issues before going for an RMA. A loose cable could be the cause, or a broken capacitor/resistor could be easy to fix at a local shop same-day.

If you have a voltmeter, look for 0.75v across the inductors (grey cube like objects)

thanks for info,i did  check all cable or wire,i measured 12V  on dc pin second hash board, and next day i will measure voltage on inductor

do you think that if i will not repair erorr myself,   they will send me new has board?

Thanks for experience

hi,and do you have any circuit scheme picture for hassing pcb board for S3 +    for better checking and fixing   error with some resistor or capacitor?

Dogie might.

Pretty easy though, the inductor has big pads. If each inductor has a 0.75v measured across it then it rules out any regulator issue. The next step would be to closely examine the chips to see if there's any obvious reason why it may not get comes or power.

 Likely it will be within the first cluster of chips on the leftmost side of the pcb, as an issue with these chips will prevent the chips to the right of them of working correctly

hi,
 i ordered two miner about 2 moths ago from official  bitmaintech.com web pages.
I am from  Czech republic Europe.
I  send lot of e-mail to bitmaintech  company.
They wrote me , for example  tests miner,change control board from my second working miner,  etc. but no succes.
Have you info about   bitmantech reseler or repair company in Europe?

I  think that second hash board is dead or damage.
for me no problem change new  board  myself.
for me every day without miner is lose money.

Hi,
i measured voltage on chain board 2   on  every inductors   1 - 8   and  only 0 or 0.15V is there,  no 0.75V
