Q:Hello ! I have 4 Antminer T17 devices and these devices works for 2 or 3 days without a internet connection. After that 2 devices had problem. actually the hash boards some time start up and some time didn't recognized. No body in Iran has enough experiment to repair these kinds of devices and the required spare parts (ASICS) is not reachable too.
What should I do ? please guide me.
A:Hello my friend, I suggest you check the power supply, if maintenance is needed, there are maintenance departments in Tehran and Tabriz

Q:Hi i have problem in s9 14th hashboard repair. I'm use fixture and found broken chip then replace that with new bm1387b but when tested it the chip does not fix. In first hashboard i'm replace chip 51 after that i was checked chip voltage and get this result : clk:0 C0:1.8 Ri:2.2 b0:1.8 rst:1.8
In the second hashboard i was replace chip 31 and after that i get this result: clk:0.4 C0:0.4 Ri:0.4 b0:0 rst:0. I'm very confused what is my problem.
I'm use heat gun in 450° to remove broken chip and install new chip do you think my new chip was damaged by tempretur? Or may be my bm1387b chip is not correct?
A:Hello, please don't use too high temperature for continuous heating, but I don't think you can find a suitable test point, which is located at the transmitting end below the chip

Q:hello i have two question about s9 hashboard.first, i want know what is chip numbering on hashboard v4.21 and v4.2, do you have any image of hashboard with chip number? second, i'm tested hashboard with fixture and found asic 32 is damaged then i'm check all of chips on hashboard with multimeter diode mode and not found any problem, please told me how i must check chips with multimeter because i watched your video more than 3 times but i can't get whats showing on multimeter when chip broken
A:Hello my friend, when the test fixture prompts a 32 error, it is most likely a failure of chip 31. Please check chip 31
