Currently, the direct warranty is provided to the customers who purchased the miner direct from http://www.bitmaintech.com , http://www.bitmain.com , http://www.bitmain.us

The warranty is valid for the original purchaser only and it does not transfer to the second hand owner.  The original 90-days warranty is valid while the 2nd hand or even the 3rd hand owner continue to own the miner, however, the warranty has to be serviced by the person/business reselling the miners.  (Meaning, non-direct purchaser has to contact the person/business who bought it from to deal with the warranty service)

OP stated in the POST#1 that OP purchased the miner from other than the URL managed by Bitmain.

ASIC Miner Company and other manufactures provide the very similar warranty service and this seems to be the norm of the industry at this time.  After Sale Service is being improved at this time and accepting any opinions, suggestions and comments, please PM.

Hope this clarify.



Before i start I want to give out thanks:
1) I want to thank cryptocrane.com for quick delivery and being stand up and helping with the Antminer problems-- super cool


Thanks guys for the support, here is the email they sent me when I was asking for help...

Before i start I want to give out thanks:
1) I want to thank cryptocrane.com for quick delivery and being stand up and helping with the Antminer problems-- super cool
2) I want to thank Antminer for making a defective unit and being absolutely no help in resolving the problem, even though silmilar problems are written about on these forums from the S2.
3) I cannot remember who it was but a guide was written about the beaglebone issues on the S2 and how to replace the card--thanks

A quick introduction, I am new to BTC and come from a background of extreme overclocking etc.  I have followed BTC for years and decided it was time to play with some mining hardware. ( I know, a little late to the party).  I purchased 2 Antminer S4's about 2 weeks ago from http://cryptocrane.com and received my rigs 2 days after purchase.  Within 2 days one of the miners was dead.  It had the dreaded amber light on the PSU.  

This is a simple repair of a fried BB board.  It may or may not be easier to replace the BB board for $60.

After a little searching I realized the PSU issue and opened the unit and replaced it with 2 Corsair units that I had in my possession.  The unit was still dead and after playing around with it I got the LCD to at least come on but then realized I had a dead beaglebone card.  None of the beaglebone LED's were lighting up.  

I continued looking online and found the guide to replace the beaglebone card and update the SD card etc.  So i ordered a couple of beaglebone cards.  This is after getting no assistance from Bitmain. The guys at cryptocrane.com were replacing the PSU's and helping troubleshoot.

The problem with ordering parts is I have to wait--- not my strong point.  So i took out the parts and went to work.  

Again- these mods were on the non working BB board and I would not suggest doing these mods on a new BB card as it would be unnecessary.

I am still not sure if the PSU or the beaglebone card went first but I would bet the PSU shorted the beaglebone card.


good friends , I have a antminer s4 + , she lights the network cable connector but no red lights and green lights in front, also i can not do a factory reset , and access it to configure , is fried the BEAGLEBONE ?

What do you believe was damaged on the old board, that the fix bypasses or replaces?

The short is located between the PSU 6 pin connector on the green board and Pins 1-8 on the expansion interface closest to the 6-pin connector  (1-8 of P9 on the BB board).  The repair actually bypasses the 6-pin connector supplying the power to the BB board and therefore bypasses the short.  I will upload some pics of the multimeter readings tomorrow showing the short etc.  I think when the PSU died it caused the short but thats just my $.02--

So how do you think the short got there and why did you not just remove the short?

Sounds like your controller is fried and not the BBB as you get connection from the BBB but not controller.

I honestly cannot remember, this thread is over a year old and it was one of my first times actually busting open a miner and messing with it.  I do appreciate bringing it back up for old times sake.
