Funnily enough, plugging it in also results in destruction of your equipment.
I agree that it is funny. However, it is not true. As explained in the news posted several months ago, only few miners had an issue that caused the mosfet to short-circuit itself. This was due to a poor design made in cooperation an Onsemi FAE. After working with Vishay's engineers we have fixed the issue.
We have been replacing under warranty all miners and/or boards affected.
I reported to you one X-3 affected by this issue:
Ticket ID: QNA-765-48102
Subject: X-3 affected by burning hashboards problem
I got no answer then (despite my inquires) and the ticket is removed.
So no, you haven't been replacing under warranty ALL miner/boards affected.
My miners (two cases of one X-3) still wait to be repaired and I've got no RMA to send you the boards.
RMA or no RMA, they demand that you send them the faulty boards at your expense. And pay for the testing if they turn out not to be faulty (which they judge, of course).
I'd imply that dealing with Black Arrow is like dealing with the Devil himself, but the Devil keeps his promises.
