Okay, I've seen this before.

1. Post pictures of the dashboard (the one showing hashrate and blade error messages)
2. Post pictures of your mining setup
3. Post Pictures of the faulty boards (close-up) DO NOT OPEN YOUR UNIT FOR THIS, IT WILL VOID THE WARRANTY, take close-ups from the outside, including the red LED near the power connectors.
4. Post Pictures of the controller board (also, don't open it) and see what lights are on.


Many people have complained before and it has typically been one of 3 things.
1. Improper settings/drivers
2. Improper setup (all power plugs need to be connected, DO NOT MIX POWER SUPPLIES!)
3. Improper usage (I've seen previous users who ran theirs outside, took pictures, then sent it off for warranty, when Bitmain called them out on the water damage and even sent back a makeshift repaired blade, then the user went ape)
