Well........looks like I get to create my first repair ticket. This is absurd. I waited 2 months for these L3+ to come in and one of them has a bad hash board. At least that is what I'm guessing has happened. recap-I noticed an X where there should've been a 0 on the first ASIC. So I rebooted the miner, it came back online and this is what happened.
See pic below
**UPDATE*** The zero's are now XXXXX instead of 0000 on the first board.
I have also noticed that this miner is making a weird low howling noise..its different from the other L3+, i will probably try to figure out how to dis assemble it and see why it is making this noise.
Its like it isn't even recognizing the miner.
I tried
-rebooting multiple times
-upgrading the firmware to the firmware on their website
-seated all the power cables
-tried a different PSU
And I still get the same thing. When I researched on Bitmains website they said these are symptoms of "Chain scission of chips" or something like that. Anyone have any suggestions? If not then I am going to ship the board to them (I guess just the board and not the whole miner?). Has anyone had any luck sending to their US Facility that they list in California? I would like to send it to them and get it warrantied. Any advice would be appreciated..

That sounds like your board is gone.... Did you OC it?
If you did not OC it, open a support ticket and get the repaid done as fast as possible. The good thing is you can keep the miner with 3 boards and still earn money.
My controll board was broken and I was not able to do anything with the miner until i got a repair
I didn't touch anything on the software other than the mining pools lol. I guess I'll send them the hash board..are they hard to take out? Has anyone used the US repair facility? Or should I just ship it to their China facility?
It's easy to take the board out, just unscrew 4 screws the side where the exhaust fan is (will have to break warranty sticker for this) and pull it out. I used LA facility and they fixed it and shipped it back in 10 days.
Thank you for the reply, will breaking the warranty sticker void the warranty? In other words, should I just send the whole miner to the US facility or should I take it apart and send only the hash board? and if I send just the hash board, do I create a ticket for it first and make sure they are ok with me removing the hash board? I noticed on their website that you need their permission but I'm not sure how strict they are on it.
Should I call the US facility or email them or should I just open a repair ticket and send it to the US facility?
Sorry for all of the questions lol, I just want to make sure that I do it right since the whole process of RMA is confusing through Bitmain. It seems like you are supposed to box everything up first or at least get a tracking number and ONLY THEN can you start the repair ticket on their website, when you have a tracking number.

Mine was #6 which says take a board out. So I just created a ticket (it was auto approved), printed a form, took a board out and shipped it to their CA repair facility.
Ok I will open her up then and pull a board. How do I know which board it is? It says #1 but I don't know where that is in relation to on the miner.
