Hi guys,
I have S9 bought in 03/2017 and the 7 hash board is turned off after switching on and does not blink the LED even at start or after.
Do you have any experience with this?
Several times she was dead after a restart but after resting (about 3 hours) or resetting to the factory setting it was OK again 1-2 months.
Now it does not help. PSU OK, control board OK, data cable for hash plate also 100% OK. Nothing was burned, it did not smell and it was visually OK.
Is there a hard reset, resetting error hash boards, etc?
Bitmain claims to send "the entire miner" for a warranty test and repair.
S9 purchased before October 1, 2016 - just send a faulty hash board.
S9 purchased after October 1, 2016 - send the entire miner. That's bad, I come up with all the performance (even good hash boards).
What are your experiences?
And what about the S9 post-warranty service (even those new after October 1, 2016) is also sent to the entire miner?
Thanks for all!
