I have an Innosilicon T3 57TH unit that has just started having a problem.
PSU shuts power off to hashboards after 90 seconds whether the boards have finished pre-heating or not.
Once boards are heated to 60C if I cycle PSU the miner goes through pre-heating at 12.9V then goes to 13.6V and starts hashing. PSU shuts power to boards after 90 sec. from when PSU first sends power to hashboards.
No errors on logs. All chips show up on each board.
At 90 sec green light flashes on daugthercard on PSU and power goes to 0V. The PSU stays on.
I have no other T3's to swap out parts with. There are 4 jumper pins on the top of the daughtercard on the PSU. Anything I can do with the pins or any other advice? I am waiting to hear back to Innosilicon to see if they can help.
