Warranty return is almost pointless when it comes to bitmain it will take you six months to get it back
Wonderful....
Assuming I'd have to pay shipping back to china, it would take a while for the D3 to pay back the shipping costs even if they fixed the board immediately. I guess it would be worthwhile then to take it apart and see if there is any way I could fix it myself.
I've had to ship two orders in the past few months to Bitmain for repair, 1 L3+ hashboard and 2 D3 hashboards. In my experience, they're very fast on returning them. My only delay on the first repair was because they closed for a week for holiday. My advice, use USPS, and ship the boards using the 3-4 day option Priority International Express or whatever its called. For a normal size box for hashboards it cost me $60 or so. It arrives, then it will take them a week to log it into their system so don't freak out when it doesn't get marked received right away. Once they do mark it received, they'll have it shipped out within 3 days and they usually ship it UPS red so it gets back to you in 1-2 days. Door to door it takes about 3 weeks.. not terrible as far as warranty repair return times go. The fact that they ship it back to you express is fantastic since it shaves at least a week off your downtime.
The trick is to ship it directly to Hong Kong, do NOT ship to California or they'll put the board on the slow boat and you wont' see a return shipment for weeks. Shipping might cost you more up front, but you'll make up for that in the mining time you won't lose waiting on California to get the board returned and mail it back to you. They don't actually do any L3 or D3 repairs on site there, so sending it to them is just adding a middleman.
