Side thought, there was also this person who bought a s19 95th machine from Amazon that was sold as new but also turned out to have issues.
https://bitcointalk.org/index.php?topic=5469920.0I wonder if a some mine just sold off a bunch of these older units and there are some Amazon sellers that are cleaning then up and selling them as new when they had actually been run hot & hard for over 2 years.
Could be a coincidence but 2 in 2 weeks, seems odd.
I can't speak for those sellers, however, one thing I can tell you is that brand-new S19s still exist, I have them in stock and I sold a few not too long ago to a forum member, of course, your theory is perfectly valid, some sellers would sell a used miner as new, it's not so hard to fake that.
With that said, it's also pretty normal for Bitmain brand-new miners to arrive in DOA, not hating on Bitmain but given my own experience as a miner and a seller, when I compare Antminers to Whatsminer I can easily tell that Bitmain gears are "shit" at best, the failure rate even for brand miners is high.
A note for everyone, brand miners have 1-year warranty from the day they leave the manufacturer or an authorized seller warehouse, some sellers will fail to sell the miners and keep them in stock long enough for the warranty period to finish, so you MUST always ask about the warranty of the miner you are buying, if it's over, you should at least get it for a decent discount, many sellers count on the buyer's ignorance, they know gears that are out of warranty are worth less but they will still sell them for the original price.
tried to run it with another PSU and the control board says “antminer BHB42XXX” instead of antminer s19 on the top right corner of the status page. Does any one know what this is thank you for the help🙏
What PSU did you try with?
1. APW121215a / b / c versions are universal with each other (no voltage feedback).
2. APW121215d / e / f versions are universal with each other (with voltage feedback).
3. APW121215d / e / f version can replace part of a / b / c by upgrading firmware, but a / b / c version cannot be used with d / e / f replacement.
https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=306I believe your miner model would only work fine with APW121215 version A , APW121215 version B or APW121215 version C.
