Have they ever explained anywhere what that PIN is? I would guess it's a MacGuffin they made up to have a universal justification for denying warranties in otherwise passable cases.

Dear customer,

Your hash board was damaged physically before we received it. It may happened in transit.
If you need the picture of the hash board, I can send it to you.

Yours respectfully,
Quentin

 Well I am not so sure  they now offer paypal which seems like they want to do something good about warranty.
I just don't want to think the warranty issue is as terrible as it appears to be.
All that happens is more people shift to Eth coin mining since  pc gear has real warranty. Any good businessman like bitmaintech has to see that they are Helping GPU mining with the current warranty issues they have.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Bitmain is currently testing payments with Paypal. If you are using PayPal to pay for your order, please note the following before proceeding:
1.We only support Paypal to Paypal payments. You have to register with Paypal to be able to use this feature.
2.You can pay for only one order using PayPal. You can NOT pay for a second order using PayPal until Bitmain decides to expand the use of Paypal
3.The order can only contain 1 unit of the each product type. For example:
The order CAN have 3 items in total: 1 AntRouter R1, 1 Antminer S7 and 1 PSU.
The order can NOT have more than 1 AntRouter R1 or Antminer S7 or 1 PSU.

I *think* PIN is the barcode sticker. As in Part Identification Number. I don't see one in the pics of Tupsu's boards.

I feel like it's a mis-translation and actually having to do with communication at board-level, kind of like a mis-described PIN diode or something similar. Either way it's utter bullshit in terms of invalidating warranties.

I don't see how accepting PayPal has anything to do with warranty, and it's clear that they're concerned about people taking positive (and warranted)  action against their bullshit warranty policy which is why they won't allow S9 sales, or even multi-unit sales through PayPal.  They fear accountability. Phil you can refuse to think whatever you want, but the fact of the matter is they treat you differently due to your presence on the forums, which was clear from you getting some compensation for one of your units after kicking up a stink about it. Bitmain is clearly short-sighted or arrogant to believe that they will never have enough competition to justify accountability to their customers right now.  But people do not forget, and when someone else comes along they will choose them over Bitmain if they had a negative dealing as well.

Well I do the give away on the diff spec thread  I promote BTC that way.  Been a few thousand dollars given away.
It does get me some benefits.

But I don't see them to be this short-sighted.  They have been pretty brilliant with gear  other then the warranty issues. I talked about the compensation on the s-7 from OCT until May  and kept buying s-7's for clients. All I wanted was a discount on the s-7's I kept buying they ignored me for months.

I still like the gear but the warranty issues have created a demand for Gpu mining Right now  at this moment the best way to mine a BTC is build a gpu rig and mine Eth coin then dump it to a speculator for BTC.

Bitmaintech has been a big factor in this happening.  I do not understand their reasoning for the anti warranty behauvior.

HeY I saw your gear burn.  This is my third bad piece of bitmaintech gear. A lot of others are freaking out with bad warranty service.

I have 2500 watts left in the solar array.

 I can go s9 , avalon7 or eth coin mine >  if I lived on the solar array site I would be more eth coin then any other mining.  Mostly due to the warranty  2 years for all the pc gear  vs 90 days for bitmaintech gear.

This is a huge plus for mining gpu coin. = FACT!


I just do not understand why bitmaintech feeds into it with poor warranty service.

BTC is not 50x ETH in market cap  more like 9.7x  so it is not impossible for a bigger shift to ETH over the next months.

http://coinmarketcap.com/

and eth hash rate is at 4.8 th  which is a lot of cpu's  40   rx 480's =  1gh  x 1000 = 1 th  so  40,000 rx 480s are 1 th about 200,000  rx 480s   that is 50,000,000 usd worth of gpus  actually more since a lot of miners other then rx 480's are in play

https://etherscan.io/charts/hashrate

and there is 683 gh in ETC hash rate https://ethc.coin-miners.info/#/ about 28000 rx 480's or 7,000,000 in mining gpus

so 58,000,000 in gear as of today.  that would be 40,000 s9's which may been sold since 40,000 s9's = 520ph.

So the gear value of btc mining gear is ahead of ETH+ETC but not by much.

Maybe btc gear world wide is 4 x the price of ETC gear
 

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Where is the picture with high resolution and with a serial number and damage ?

 Customer Service-Overseas Today at 11:11

Dear customer,

Sorry to keep you wait.
As you can see in the attachment, two heat sinks of the hash board dropped off, which lead to the PIN lost in circuits board. The hash board is likely to be hit in transit.
Our engineer have tried their best, but it is no use. It can not be repaired anymore.
We suggest you to make a claim to your logistics agent.

Please find our returning policy in the attachment.

Yours respectfully,
Quentin

Even if it is my haschboard, Why do not the pictures taken when a loses radiators was detected?

See Request #12212 what I opened, when you got the package.
You got the package 2016-08-07.
To get these injuries , Box had to be physically damaged, bruised or open.
Why then did you not informed of the injury courier companie?

If there was no external injuries on the box, it could not have happened during transport. The same could be happen during the repair process.

How can you be sure that it happened during shipping not during repair ?

I'm not saying it's not well deserved with everything you contribute to the community, I'm just saying it would be difficult for you to give an accurate account of Bitmain's warranty situation when you aren't necessarily the norm. They clearly respect your presence on the forum.  But this:
seems like they want to do something good about warranty.
I just don't want to think the warranty issue is as terrible as it appears to be.

Is just not representative of my -and by the sounds of it many other customers'- encounters with Bitmain's warranty department.

Tupsu, I'm sorry man.  That is really shitty, and I feel for you.  I'm to the point where if I can't justify a purchase of 100+ units, it's just too risky for me. And they don't deserve that kind of business. We should've got into GPU mining months ago.  Undecided

The Antminer S7 is a piece of shit. I have purchase 6 total and had nothing but problems. Hash boards stop working, powering them up and ASICs are shooting flames out the fan, etc., etc. I will never purchase an Antminer again until they get their shit straighten out. All they do is blame everything else (P/S, Internet connection, etc.) Yeah Bitmain, my Antminer went on fire because I lost Internet ! You are absolutely correct !! Jerkoffs. I will do my research on the S9 but I assume they are just as shitty, if not shitter because instead of being out $300 - $400, you will be out $1500 ++

I stayed away from the S9, and it sounds like I may have been wise to do so.  The performance on them is good (w/TH) but from everything I've heard, they have been more unreliable than the S7's were.  I just can't justify the kind of risk from unreliable machines like that, if you don't have 100x units then the risk of having 1 fail will eliminate any chance you have of ROI, I know it did with me for the S7's I bought.

Actually this is a known issue with the S7s and firmware on or before Nov 2015. I lost 40 units to a failed switch once. All you have to do is upgrade the firmware to the May 11th/23rd 2016 firmware and that will not be an issue.

Stop buying industrial miners, running them at home, and then complaining about the noise.

The unit in question of mine that erupted into flames had updated firmware, and AFAIK no loss of internet connection.  The point is more-so that Bitmain will use anything to try denying warranty even within their short warranty period.  They tried denying me on time period (even though I had started the RMA process prior to warranty ending), on internet (dozens of miners on same switch), PSU (even though 3 units were connected to the same PSU...) and finally because burnt boards are not covered under warranty, even if they fail due to problems with the hardware (I don't even know where to start on that one  Huh Huh Huh).

I have seen a few odd machines here and there catch on fire for no apparent reason. I know they did not coat the s7 boards with nay protective material and you can actually build up enough dust to short out the boards. Corrosion is also a well known killer of s7 boards. If you have high humidity that could be a cause for concern as well.
