Bought myself an antminer s9 from aliexpress come to setting it up and one of the hashing boards doesn't seem to be powering up, when i logon to the miner via my internet browser i can see boards 2 and 3 hashing away as they should but its like board number one isn't even connected so i switched some wires round to make sure they was all good and that it was not the psu and realized it has to be the hashing board thats faulty so ive taken it apart had a look round and there is a dent in one of the capacitorshttp://i.imgur.com/F9r24au.jpg http://i.imgur.com/QOAJXyF.jpg so im thinking this is my problem, anyone with a bit more knowledge than me id appreciate it if you could tell me if this is my problem or not? and if this has likely caused any more damage to the hashing board perhaps? or if a simple capacitor swap will do the trick maybe? ive only just got the miner so it should be still under warranty, this is the seller i got it from "BitPowerOn & EastShore Mining Devices Store'' so i should be able to just send the hasing board back then they send me a new one or just fix it, or do you think its worth just doing it myself and saving hassle of shipping back and forth?

BTW im a bit sketchy from the people i got it from as well as the miner was meant to be brand new which it clearly wasnt, one of the screws has been slightly rounded and the warranty sticker cracked so to me somebody has been inside, they also sent me a screen shot of it meant to be working before it was sent which was balls it showed the miner hashing with hashing boards connected to points 2,3,4 on the controller not 1,2,3 and funnily enough its no. 1 thats not working, so im not sure if they tried pulling a fast one hoping id be a mong and never notice?! im not sure any input from you lot would be appreciated! thanks

My guess is they did pull a fast one on you intentionally.  I am not sure what returns on aliexpress look like so maybe you have some recourse there, but since you did not buy it direct from bitmaintech I would say there is no warranty you can rely on (plus the bitmaintech warranty is questionable anyway).  Bitmainwarranty based out of Denver (not to be confused with bitmaintech based out of China) could probably tell you if that dent is likely to be the issue and could also possibly repair the board (depending on the actual problem with it) for a fee.  So yes bitmainwarranty, despite having the word warranty in the name, is a fee based repair business.  But on the bright side they operate with a high degree of professionalism, they are timely with repairs and communications, and they are based in the US, so for US miners they are a very good option for stuff that isn't covered by the actual bitmaintech warranty.

thats what im thinking, they tried having my pants down the cunts, this is where im unsure on what to do thought with ali express i can open a dispute get a full refund and send the item back or keep the item and get a partial refund?! i cant decide, if i could just replace the capacitor and everything be fine and dandy id do that and get some of my money back, there is an electronics work shop at work so i can do it there but id like to know if anyone this this will solve the problem or if anyone knows if the damaged capacitor could have caused further damage? yea i have no official warranty with bitmain but i do have some with the seller so they say, also im from the UK not US unfortunately. just not sure what to do id have to pay as well to send it back to china for a full refund so thats probably 30-60 quid down the drain doing that

basically  you got f''d. 

I have not done any business with ali-express  not sure how they warranty gear.

So check with seller see what they say.
Check with ali-express see what they say.


China --- bitmaintech.com      they may do zero for you  as it is not under warranty from them.  They say send none warranty gear to bitmainwaranty.com for repair.


USA-----  bitmainwarranty.com     they will fix for a fee. --- my best guess is try for them to repair it -- try for seller and or ali express to spring for repair.



Good luck  and please follow up if you can .  Please let us know if someone helps you.

it seems a bit like how ebay works it seems quite good, i have uploaded pictures of the damage and stuff for the case ive opened

ive opened a case and requested for a full refund and for me to send the item back (as a preferred method)
the second proposal i made was a partial refund of 1000 pounds and i keep the item and i pay to get the hashing board fixed (take it to work and replace the capacitor and hope it solves the problem, if not send it off to an expert. they have 5 days to reply.

yea ill update as i go along, just be careful anyone else ordering with that company on aliexpress, the seller has good feedback 98% or something and they specialise and sell a range of miners but there is no denying here they have tried to scam me, and they dont seem to be responding to me now, if i left it longer than 15 days i wouldnt have been able to open a case and i think thats what they was trying to do just delay it all! ill update as the situation moves on!

thanks for your input pal, it was paid by card but aliexpress hold the funds until good feedback is left or until any disputes have been resolved i think
i think im able to get a refund i just need to send the item back thats all

and ill have another look at the board, the only damage i saw was that capacitor though but i could have easily missed something else as im no expert on them

ill update if i find anything else
