Topic: So just how hard is it to get BitMain to fix warrenty repair? - page 2. (Read 2745 times)
Took me over a month to get my card replaced. And in return they sent me a Used working has board for my S7
From the USA my cost shiping to China using UPS's cheapest international was $75.
If you ask they will let you send USPS which cost me about 17 bucks for an s5 blade. They paid to ship it back.
I have a total of 3 S7.
This is the most recent one that I have got from Bitmain. IT still has 2 fans.
This is the power supply:

2000watt
I have this on all three. The PSU run cool to the touch. All have at least 12.37 volts under full load of the S7.
This unit ran perfectly for around 46 hours before taking a HW rate shot up fast.
I have tried different power supply.
If I run just one board at a time:
Board 1: shows x's on all the status slots. But says ASIC# 45
Board 2: shows x's on over half. Also says ASIC# 39
Board 3: Show all o and all ASIC# 45 and hashes around 1.52th
Temp all show below 48c or lower.
If may be easier and cheaper to just wait till I mine enough BTC to buy another one and use this one for parts...

RE here https://bitmain.zendesk.com/hc/en-us/articles/203361315-Board-Diagnostics for what you can do as basics checks -- and how to remove boards from sinks. (does NOT apply to the s7! They want the whole boards)
It is for an S4 but still applies. Somewhere they have a page on others as well...
edit: duh, just click back a like to the Troubleshooting home https://bitmain.zendesk.com/hc/en-us/categories/200236359-Troubleshooting

without voiding the warranty you ARE however allowed to swap the controller cables around to verify a cable or socket isn't bad. It probably be something they will ask you to do so try it ahead of time to save on playing email ping-pong before they issue an RMA.
Technically they pretty much have it where you cannot do anything with current policy. I know people do try things such as this without contact. But they have pretty vague terms:
Customer removes/replaces any components by himself without receiving permission from Bitmain first
They have never not accepted RMA due to changing cables that I know of. But "componet" being removed could cover just about any physical change. Full warranty is here: https://bitmaintech.com/productDetail.htm?pid=000201603310959482268cfunbq106E5 I'm not saying it's a good thing as I love to tinker. But they have a very vague warranty at this point that could be read many way's with it being vague.

So I get a S7, runs great for 2 days. Then BAM, HW error rate jumps. Blade 1 and 2 now pretty much dead. Blade 3 running great! 1.5th easy.
Blade 1 and 2:
If i connect them each individually they show many failed chips and barely hash, around 22g or less.
So I see that I need to open a ticket and pray that they will respond and maybe help me?
Is that what I have been reading...
Any helpful hints with dealing with them would help!

My helpful advice is don't try to do anything physically to them, basically opening anything voids warranty. Assuming this is a new one from bitmain send the order info and problem in email and ask for a RMA.
Just to be sure what PSU are you using for your S7? (making sure it has proper power). Also out of curiosity is it a new one fan with having it only 2 days?
I've only had 2 problem miners, a s5 and and last Feb a s7. Both had DOA cards. Filed the repair ticket, they got back in a day or so with a few questions I answered (also had made screen shots of the GUI's showing the problem).
They got back with the RMA procedure. If you are lucky and is not all cards, the bad card(s) will need to be returned at your expense. In both cases I got a replacement card 2-3 days after UPS said the got it. Dunna know how so fast They pay the for shipping the card(s) back to you.
From the USA my cost shiping to China using UPS's cheapest international was $75.
