USA, Russia, Ukraine, Iceland and other limited service location are primary repairing the original item send in as the priority, however, if the damages are extensive but repairble, to reduce the mining time loss, the repair cost estimate be issued based on the actual damages but the replacement PCB may be send out to you to save a few days.

Main goal is to return the same PCB the customer send in.  Also, if we do ship out the replacement, BitmainWarranty.com will offer 30-day limited service guarantee (workmanship guarantee) on the item or retain the original warranty duration of the unit whichever the longest.

Usually, bad S9 hash PCB can be repaired and ship back to the customer the same day or the next business day.  (common duration be 1-3 days but the main backlog be after the repair is confirmed, the time delay while the customer service rep wait for the payment from the customers.  Item will not be send out until the payment is received in full.)  Some occasion, notification email seem to end up in the Spam folder of the customers.  Other few days delay from customer opening the new ticket (sometimes with a different email address inquiring the same repair on another ticket number)
