Topic: My warranty adventure with my s-9. (Read 4783 times)

30 days of workmanship is provided, or remainder of the original warranty term on your S9 whichever the longest

Repair cost on PCB can be $0 to the cost of the PCB depends on what is being broken.  Some received $0 repair as it was manufacture's defect and very few required PCB replacement at full price.  If you bust several ASIC chips, they will not be cheap.  

Looking for a better way to lower the cost to all in general but everything in USA has costs. 

that was my assumption, but they sent the board back (after charging $200 for repair) with email that "your warranty has expired"  
Wooot???

What was in your email, Phil, if i may ask? Anybody, feel free to contibute on what you got (in email)

30 days i think.

hey, Bitmainwarranty...Do you provide ANY warranty on your repairs, for example paid S9 board repairs?
What exactly you guarantee upon completion of the work?

yes i did not do either one and you can see how confusing it became.


I just got a corrected invoice in my emails and I paid it off.


Thanks for you help. Looking forward to getting the new parts.  thanks

HI Guys,

To ship item for repair, No Paperwork filling is needed, HOWEVER, please email [email protected] the item description and what is wrong with it.

You will receive an email reply with the Ticket Number to include in the package to Denver for the repair.  Paid Repair is available for any Antminer users.

If our email does not arrive in time, please check your SPAM folder for just in case!!

I did find 3 emails in my spam section on my yahoo account.

yahoo.com is becoming a very old tired company but it is besides the point.

So I fucked up.

now the funny thing is I went to pay the bill for hashboard repair of my s9 650 m board and rma on my controller

bill is 90 + 25 shipping for the hashboard

bill is free for controller.    total of 115.  and bill is from 10-18-2016

so my fuckup cost me 9 days.  moron that I am.

but I took a good look at the bill and it is for an s7 hash board 700m

So they fucked up.  While I feel better that I am not the only fuckup I am now waiting to get it corrected.
this is why  trying to be civil and polite is important. clearly below they made an error.

but my 2 errors were to not find their emails and I sent this order in without the best paperwork in the first place..

So  below is the newest issue which is at least somewhat my fault and somewhat their fault. This is an effort by me to be transparent and show that part of this is my fault . I am also sending emails to yoshi.

thanks for a reply here.

It is now the 23 rd and no follow up that I can find.

But I get so many emails I,may have missed one.

I will take a good look on Monday and post back.

It is one freq 650m board no warranty.

It is one unified one board controller from batch 10 under warranty.

Hopefully I can get some action this week.

Multi Language issues, we are working to fix that bug.  Sorry for that confusion.  When you send item for repair or diagnostic, please please each shipment, please email [email protected] and obtain A TICKET NUMBER and include in the box.  Other wise, techs may confused with your previous repair request if they receive new parts for repair.

Example, you send in S9 hash PCB previously, got it repaired or replaced.  short time later, you send another S9 PCB, it may get over looked as when they look up repair request que, it shows, it is repaired already.

you will receive auto response with ticket number when you email [email protected] for paid repair, or included repair if you purchased local service plan for 90-365 days.

techs are trying to speed up the turn around time as much as they can.  Some hash PCB when it shows not so much hope in repair success, another tech is spending time the next 2-3 days, looking at it as second opinions for higher repair chance!

Thank you!!

I got that same Russian email a while back.  I had a repair maybe in June or July or something, and the email was regarding that.  I believe all it is saying is that the warranty on the repair work is ending.

A follow up on my s9's

I had purchased 6 of them

4 just always worked.


2 had multiple issues.


my newest one in august.

had a bad hashboard  it was replaced. for shipping fees only


it then tossed it controller .  I am still waiting for a replacement for this controller.



my bad batch 1 tossed a board it was replaced  for shipping fees.


it tossed a second board after warranty   I sent it in and I am still waiting for the verdict.



in the meantime I purchased spare controllers and fans.

So I am using one of the spare controllers.  in the batch from august.  but it would be nice to get the controller i sent in replaced under the warranty.

So  totals from 6 units are 3 dead boards and 1 dead controller

rma's sent back from bitmainwarranty

are 2 hashboards  for shipping


rma waiting for 1 dead controller

repair waiting for 1 dead hashboard.

So since august  purchase of the sixth s9   it has basically been a hassle still not fully fixed.

And I made 450+ in parts purchases  3 controllers 2 fans.

I got so tired of running back and forth to the solar array I sold 3 s9's  and I am down to 3 s9's one of which belongs to buysolar as part of our deal.

So here I am with  lots of cheap power  most of it idle. 19 amps x 240 volts  used and 38 amps x 240 volts  idle

I am sitting on coins wondering if I should just switch to eth coin in the array.

I did not mind  gear breaking and bitmainwarranty was pretty helpful but  my last email from them was on Oct 7th:

Hello,

We have received a repair order in our Denver repair location. There was no current ticket number with the shipped order so i am just going to refer back to our most recent ticket here. Our tech will now begin diagnostic testing and once that process is complete i will have more information for you on repair. Please let me know if you have any questions until then.

Thank you.







I then got this one in my spam which I found today. it is dated Oct 12th

So  it is in Ukrainian or Russian  

And it does not match the gear I sent in 1 hashbaord  1 controller.

However It does match  the first repair of two dead hashboards. Which is over and done.

So I am posting here and will attempt to follow up with Yoshi Goto later today.

As I am still out 1 controller and 1 650m hashboard.




It is obvious the multiple languages are causing confusion.

The repair techs  think it is for the first 2 bad boards. 

This is for 1 bad board and 1 bad controller

the board is not under warranty.
the controller is under warranty.

it would be nice to get the gear back up to par.

about 5600   Then tack on 400 for gable fans  so 6000 watts.

buysolar is running a sixth s-9 and 1 s-7  so 8300-8500 watts.

my deal is the 5 miners belong to me I provide 100% service parts repair cost.

The power  solar array is his he provide 100%  of that cost.

we split the coins.  on the five units. 

 so my power cost is constant it is 50%

so when we switch out gear he gets the better hand in the beginning of the new gear cycle.

As the gear ages I get the better hand in the latter part of the gear cycle.

What can go wrong for us.
gear breaking and not being covered via warranty is our biggest risk.

We need slow diff growth and stable gear.

How many watts are you at??

installed two replacement boards so all 5 machines working at kano. 

all are clocked at 525-543 since it is supposed to get hot on weds.

the sixth one is at bitminter.

back to the daily grind

heres to hoping it stays up

two side by side






a v2 which should be 650m freq




a v4 should be 550m freq

Got the photo?

Second board is on the truck and I will get it today.  this was a 650 board I wonder if replacement will be same.

I will bring gear to solar array on tues and set it back up.

I have 2 boards one is marked as a 650m v2 the other as a v4 but no freq it should be a 550m  but since the lowest rated board is a 550m  no marking of freq should not be an issue.

I will install on tues.

along with sloppy/finksy plates for dual dps- 2000 psu's

I will post a phot or two here with the new boards in just a minute or 2.

I looked wrong.  My last 650M Antminer S9 shipping date was
2016-06-13

So i opened the ticket and sending him back. But I not send back second blade from this miner , with only 3 x "X" at freq 650 and no X at 600M and 550M

I think that 13 x X are too many. 

Tough call  but  if it shipped on the 21st you have 10 days to decide.

if you wait 6 days and another board goes on you  you can ship the two back to China and save on shipping.

So I would wait for 6 days then decide.

My second board is on its way back to  me.
I was able to do it all with in the USA but they did die a week apart  so two sets of shipping.

18 + 25 = 43
18 + 25 = 43 a total of 86 in usd.

If I had shipped to China  I would have spent 110 + 110 = 220  or 140 + 140 = 280  One is UPS price other is Fedex.

so China is  220 to 280 due to two shippings vs  USA  86 with 2 shippings.  That is a big difference in shipping cost.

I have yet to mount the first replacement board.  I plan to do both at the same time which should be monday.

It is not so difficult sending them to China

I opened    Repair Ticket  2016-08-27 08:13:47
Shipped with EMS  27.08.2016 12:08  [ 2 hashboards , shipping costs about 85 euro]
Delivery  China, Hong Kong  01.09.2016 11:44

Repair Collect Send    05.09.2016    9:57
RepairOrder Payed Send  07.09.2016  4:40
RepairOrder Send Send 07.09.2016  12:07

This means that they are now shipped with UPS to my place
Shenzhen, China    07/09/2016    16:23    Collection Scan



EDIT.

I got my hashboards  back today.

So 15 days - China versus 17 days - Colorado.


This time the winner was China.  
I got  even back today the replacements for this blade , which they refused to repair.

But today I have still one broken 550M blade from last ordered miner  ,  no visual injury

 and one 650M blade, that works with 13 x "X" at freq 650 but works fine at freq 550M
Unfortunately, this 650M blade  is almost  out of  the warranty.   Shipped 2016-06-21  

I do not even know ,  sent it for repairs  or not.

Phew, whole thing stopped hashing. rebooted and all ok.

Dropped the frequency down on the remaining units a tad.

Hopefully sending faulty board off for rma tomorrow.

Good to see you got one of yours back Phil!

Oh, OK. I misunderstood, I thought you had one board coming back from china and another from Colorado.
Sure wish I could have gotten my in-warranty parts replaced from Colorado instead of spending over $$$$ to send 3.8 pounds of parts to china!!!
Just thankful they have seemed to honor the warranty and I should be getting 2 new boards to get my miner up and running again! 

Be happy for the small things!

From UPS tracking  -
Scheduled Delivery:  Monday, 12/09/2016, By End of Day

I Shipped with EMS              27.08.2016 12:08

Thus, the same 17 days as with the Chinese guarantee, if you are lucky.
And this time I had.
Remember,  that with my first S9 650M hashblade  was 43 days, until I got it back from China and it was the replacement hashblade, what I received.

sure now I was NJ to Colorado to NJ

no China shipping

I sent it out via USPS.com priority on August 22nd

so Aug 22 to Sept 7

Philip, did they send you a tracking number when it was returned to you as I would expect? Can you please give me a basic idea how many days after you received the TN that your replacement arrived? Just trying to get an idea when I might be able to expect to get my miner back online!     

Much appreciated!!!!!! 

dead board sent in about 2 weeks back





replacement came today

will post a photo of it sealed in static wrap

Looking at my pool stats it appears miner #2 has lost a board

Will ssh in  and check when I get home.

When I contacted Colorado about my dead board a few weeks ago, they said they were not repairing S9's and had no parts. But said "maybe soon".
Maybe that has now changed and they are doing S9's now. Or they are giving a known and repeat customer preferential treatment. I hope it's not the latter. As we all paid for our miners and deserve the same response in repairing them.

Although I did not buy my S9 directly through Bitmain at all, mine appears to have been repaired under warranty in China. Even though it cost a small fortune to send 3.8 pounds of parts via UPS to china.

I received this to day from B-Man:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hi, [email protected]:
Your repair order has been Payed.
•   Expend: 0BTC
•   Order ID: xxxxxxxx
•   Repair ID: xxxxxxxxxxx
Order Details
Device Name   Count
Hashboard S9(12.93T 600M)    × 1
BB Board（S9-C5）    × 1
REPAIRORDER PAYED

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I am assuming this means that my parts are covered by warranty and they aren't charging me anything.

Also, on the repair ticket it's just as cryptic. It says under Pay Status "Payed" and under Replace Status it says "Hava Replace". Not sure what the "Hava" is supposed to mean. I thought it might be a truncated word, but I can't imagine what it might be. Hopefully it means my parts will be replaced by new boards.

Has anyone else going through B-man in China for a warranty repair received something similar? What was your experience and outcome, please?

Hopefully, it will be making it's way back to me soon. It's the only one of my S9's that has ever found a block!
It will be very nice to get this S9 up and running again, bringing my mini-farm up to 4 S9's - as long as the others keep hashing and don't start dying off one by one.

I will update this when I have more information and/or a tracking number. Then when my parts are received.

Also, thanks for any light from someone who has previously experienced this form of communication and similar notation on the repair ticket might be able to shed on this information.

Best wishes all and happy mining!

@Biffa,

There is no way to diagnose without really testing the hash PCB.  Replacement be $500-$600 per hash PCB.  If its not repairable in Denver, its not repairable in Hong Kong or other way around as well.

S9 repair cost we have seen so far range from $0 to $300. ($0 being range from misdiagnosed by the customer on good parts to manufacture's defect that was replaced upon inspection and some circumstantial exceptions granted to original warranty item which is very rare.)

Also, if you are using the original shipping box, for USA customers, we can offer prepaid discounted shipping label for $18 per S7 or S9 unit to be returned to Denver, Colorado.  (Other-way to Customer be $25 per original shipping box) *$18 price is if paid by BTC.  Paypal payment on shipping label be  higher.

Repair Cycle Preview.

Most UPS delivery are incoming in the afternoon.  By the next day or the following day, customer will receive notification of status if fixable and if so how much is the price.  (Estimate does not change even tho it was discovered the further complications may require additional repair)

Some repair may be finished the same day or the next day, some may take about a week.  (Near dead or extremely damaged item with really not much chance of repair,can be placed on repair at available basis)  If the item is not repairable, you will be asked to pay the return shipping and everything be returned to you.

No repair ticket be needed, simply email your contact info and problem you are experiencing to  [email protected] and include the auto generated ticket number such as #1234 inside the returning package and one of the techs will contact you when the box is assigned to him/her.

*If the package contents arrived damaged, you'll receive photograph of the content of the package.  If the poor packing of the content result the damage even tho the exterior packaging was not visually damaged, we can not offer false statement to your carrier that content was well packed to meet international shipping standard for such weight and content materials.  

No.
I sent him along with another full not working   hashboard from the same S9 miner back to "happy miner's land" for repair .  I paid only 15 euros more to shiping two boards together.

which seems to be the more common result with the s-9 since the chip is 14-16nm and size matters when you carry power/current.

On the 1 chip failing bring down the whole board:
Depends on how it fails. There is a coms section that to some extent is separate from the SHA hashing cores. As long as the chip as a whole has not blown then you see x's because data is making it through it to the rest of the string, just not being hashed in the x chips.

If the entire power area inside the chip fails or something else equating to the same thing -- game over for the board.

that has yet to happen to me with the s-9.

used to happen with
s-7
s-5
s-3
s-1

and with every one of them  a lower freq would bring it back.

but I suppose  you tried a lower freq to see if the x comes back.  say 593.75 or 587.50?

Not always.  My 2 blade miner  with one X

@Biffa

You can send in S5, S5+, S7 and S9 for repair by fee to Denver, USA location.  Its all depends on the damage and what is needed for the repair.  There is no flat repair fee as each case is different.  

If you send in the unit that has original warranty remaining, there still be a fee for the repair, or you can send them to Hong Kong and request warranty service from Hong Kong. (usually the repair expense is cheaper than total expense and lost mining time you may experience when you send it to Hong Kong)

If you use BitmainWarranty.com as your repair solution with the unit that has original remaining warranty period, your remainder of the warranty period, be eligible to be serviced from USA or 30 days from the repair shipout date from Denver, whichever the longest.  

If the unit is purchased from Bitmainwarranty.com site, then you will have option of receiving full warranty service within USA, Russia, Ukraine, Venezuela or EU Region.  (EU customers will have the same 90-day localized warranty with up to 2 years of repair parts availability guaranteed)

REPAIR SERVICE REQUEST from BitmainWarranty.com does not need a full form be filled.  Simple email to [email protected] and you will receive a ticket number in response.  (Please include a piece of paper with the TICKET Number and possibly write down the number at the bottom of the box outside)

*damages from poor packaging or damages in transit, we can not be responsible for the loss. Please package each PCB with 4-6 wrap around and separate each PCB with cardboard in between, so no PCB heat sink hits each other while in transit.  (Also, if you are in Venezuela, heavy duty PCB packaging box with bubble wrap is available for purchase, or you can ship them to Merida, Venezuela and it will be re-packaged and then send to USA for repair and returned to you via Local DHL delivery.  (This method may save you the damage in transit risk, however, it may take a few days longer in total transit time as we consolidate shipment)

If you are as well known & popular as Phil...yes 

Sorry Phil, that's not quite clear for me, can you elaborate?

I thought bitmainwarranty only did chargeable repairs/replacements, primarily for out of warranty situations.

Are you saying that all you are paying is the postage and they are replacing/repairing the boards free of charge within bitmains warranty period?

Is this service available to anyone in the US?

Thanks

so a replacement for first is on its way due on the 7th

en
second one has be received they let me know it came and that they are checking it.

so maybe I get on on the 7th and the second on the 9th.



maybe 85 for shipping  and 8-9th offline for 2 weeks

this was NJ to Colorado back to NJ

will post more on this soon.

well  I have purchased  from them since 2013.. 

A lot of coin maybe 130-150 btc over 80000 usd.

I am guessing that has to help get some service.

But this should be normal for all buyers. That is what a warranty should be.

I really hope they resolve their warranty issues across the board.

I wish they would come up with a better one for the R4 90 days is short. For an item that does not Roi until 330 days

Beautiful! See now that is how I would expect a warranty process to work, paying shipping is very reasonable. Is this level of service tied to your presence here on the forums or on your purchase history? I'd like to think that Bitmain would provide similar levels of service to all customers... In any case, im very happy that you're slowly getting resolution.

On first board I think I am paying shipping from NJ to Colorado and back to NJ. Total of 50 usd.

Second board has not arrived it had no visible marks. tracking says they will get it on the first of sept.

So maybe that will be a just shipping deal also.

this is from a batch one looks perfect notice nice straighter heat sinks then my batch 10 a few posts up

Are you going to be expected to pay?

Got an email from yoshi  they should be sending me a replacement  will give me tracking ,


I will post on this when I get tracking.

yes it is I am packing second board  and will ship to colorado today.

That's good news!

I may check router logs at the solar array when weather cools a bit.


Some good news on board replacement.

I am sending in the second board after a contact email from Yoshi this morning.

I may see replacements soon.

I will update as time goes by.

Still, checking the router logs would be an easy check to see if all of a miners attention is focused where it should be. One thing I've done at home and work is have all the miners routed to end up at 1 port I've dedicated as miners-only on the DSL router. Other parts of the networks feed different ports. Makes it easier to track overall data usage.

Now if it was/is a targeted attack at the ISP -- much harder to find/prove. The case in Chicago (I think) involved a tech at one of the ISP main sites so he looked for traffic to known pools and had a script periodically re-route to his choice. Involved a hole in Stratum. He was caught and that hole is long ago patched (was in 2014 I think).

Yeah the solar array is at forum member buysolar he lives four mile from my home.

Query re the miners at the solar farm needing different Words and routing through a 2nd router.
This seems a better place so not OT in other threads

Ever look at the router logs and filter by traffic to/from the miners addresses to see if something nefarious is going on? Should always be the exact same connections.

Is a suggestion from Opieum2 via Skype. Dunna know why no one else including me didn't think of it... just too easy   Could also have a packet scanner/sniffer running to see where they go. Is outside my realm so aks others...
Query: Is the farm connected to a different ISP than is at yer home where this issue doesn't happen? There is a rare and unlikely sitch regarding this exact thing so has to be asked. Google ISP btc mining hack

Too hot for GPU ?

Look I do  not hate on bitmaintech.  They sell gear to anyone that pays them.  That is flat out better then most every other asic company on earth.

Avalon sometimes sells gear but they cost a bit more and do not always have the gear.

Bitmaintech is even smart in asking a ton of money  for the s-9  and the new R4.  Really good business tactic.

But they have to fix the warranty process.

I sent one board in last week it arrived on Wednesday  I do not know its status.

I have a second bad board  I want to send it in and I am awaiting an email from Yoshi to send it to Colorado vs China.

This is a bad way to encourage sales.

 I now have 4 units all running lower then stock for fear of burn out.  so 4 x 13 = 52 but I am at 4 x 11.5 = 46

I have two units with 2 boards  doing  7.5 each = 15.0 th so 61th  vs

  6 x 13 = 78th   a loss of 17th.

so between two dead boards and downclock  it is a ton of hash power lost.

It is not so much that boards die.  It is the replacement system. 

I am looking to expand  I have 3500 maybe 4000 watts   and I can't see using bitmaintech.  A dead unit can take  weeks for replacement.

Most likely I will lean towards a new gpu machine.


Maybe Yoshi will answer my email today. With good news.

Sucksssssssssssssssssssssssssssssssssssssss 

Sadly  the second board is dead.

Also  sadly  no notice on the first board.

So with 6 s-9's  and 18 boards I am down 2 boards

or 16 and 2

or 88.88% good and 11.11 % bad.
 

I just emailed yoshi goto in colorado hopefully he will tell me to ship second dead board out to him today or tues day.

So did you hear from Yoshi about your first board?

And whatt about the second board on the older miner?

Maybe not sure and I am tired of climbing the ladder to the solar array loft. I will check it on monday.



image below show two "bad" boards.

I never overclocked my s-9 antminers
Basically they ran hot so I d not overclock.


I never let temps go over 72 102 c

Mostly kept them at 65c 95c

This machine is about 78 days old I think it shipped on june  12th  since  my earliest machine shipped on June 12th I got it on june 14th

So what happened now Phil?  A second dead board?

Okay  My new s-9  died after 10 hours use just one board not all three.
I am somewhat of a player here are my purchases from bitmaintech  just the s-9's and the s-7's

S-7’s total --------53.9619 btc

over 73 btc in s-7’s and s-9s

not to mention

s-5’s s-3’s s-1’s

So  Over 73 btc on s-7's and s-9's  and at least 50 btc on s-1's, s-3's , s-5's  lets say 125 btc in gear.

I had a dead s-1 damaged in transit.  Yoshi and the old dz-coop replaced it via cross ship .
I had an low hash s-7 took 6 or 7 months  I was given 150 usd in comp.

I have a s-9 did a thread on it    https://bitcointalksearch.org/topic/how-low-can-it-run-whats-it-the-batch-10-s-9-1590910  and it details how to make a quiet low noise s-9

I guess bitmaintech had the same idea as they now have a quiet miner listing

https://bitcointalksearch.org/topic/bitmain-announces-the-antminer-r4-and-apw5-power-supply-designed-for-silence-1597639


So my miner dies one board after ten hours use.  I contacted Yoshi in Colorado and shipped the board to him.
Board arrived on weds the 24th




I await news on replacement of it.

Meanwhile it looks like I have lost a second board on an older s-9 I will check  it out on monday.
