Hi Guys, this is my problem:

I have one antminer S9 that doesn't start up when plugged in (the machine worked fine for 2 months), the only thing that works when plugged in is the fans, all controller board lights and hashboards lights are off, I tried replacing the PSU and it didn't work.  I think that the controller board is damaged and that is the cause of the problem. My question is, can I use one controller board of a working S9 to run the hashboards of both machines, can I run two antminers S9 with only one board controller???

Thank you very much fanatic,  that's what I wanted to know 

Hello, guys, I have a quick question here. Are these chip temperatures within the normal range for an antminer S9



Are these chip temps ok ? the maximum temperature I've seen on a chip is 91, which is the safe Temp Range for the Antminer S9

Thanks in advance

Hi, thank you all for your responses, I've tried the s9 with another PSU and the same thing happens, only the fans turn on, the control board and hashing boards are still off, so it's NOT THE PSU, I think it might be the Control Board. Please if anyone has a similar issue let me know.


I wasn't in the room when the s9 stopped working, there was no storm, its possible there was a power outage but i have a 30 amp power regulator, and my other two machines kept working fine, only this one presented this problem.

Any help is appreciated it,

Thanks in advance

Hi, I think the Psu is working because the cooling fans powers on, but not the control board or the hashing boards,  tomorrow I'll try another psu to check but I don't think It will solve the problem. the s9 has been running for a month and half with no problems until now, i have 3 s9 and only this one stopped working. Thanks for your advice I'll check and let you know if it worked with the other Psu.
 

Hello guys, I have a problem, one of my antminers s9 only turns on the fans when plugged in, all lights are off, no network light, no hashboards lights, nothing. Could it be that my control board is damaged ? what could have caused this ?? thanks in advance!!
