So you know which hash board is broken?
Then you can replace it with a new one.
Ask Canaan for spare part or see www.zeusbtc.com

No . The hash board of the device is broken and did not work with the pmu board anymore
Can you first answer my question / tip?
ok dear
Do you know the association for miners' repair workers or do you know any training videos for repairing Avalon miners?

I have not repaired them at component level.
Does those hash boards work ok with the other PMU board?
Sounds like there could be a damage in the PMU board?
If so, you would need a replacement PMU board, like from Canaan or www.zeusbtc.com store.
@Fuzzy, trying my best but I'm not always here

It would be best if you move this thread to the Mining Support area rather than opening a new thread about it there. Forum mods strongly discourage multiple threads on the same topic. As creator of this thread you should see a 'move topic' button at the bottom-left of the webpage to do that, then delete the duplicate thread.
HaggsFIN is the only one here in the Forum that has attended Canaan's repair/troubleshooting classes (link to it is below in my sig) so hopefully he can give you better info. While rather surprised he has not yet showed up here, I suggest you contact him.

Yes you are right . it was a typo . My mother tongue is not English and I speak Persian.
When I turn on the device, the gh15d tripod regulator on the pmu board gets very hot.
I disconnected the boards from the device. and by multimeter bizer chech vcore and gnd . i see short circuit.
so I want to know exactly where the short is from and how to test ic a3210mt

1st it's Avalon. Not Ovalon.
2nd you say 'power supplies' - as in more than 1. Are you using 2 or more PSU's to power the miner? If you are you MUST make sure that the PSU's are not connected to the same side of the miner.
You can use 1 PSU to power 1 set of plugs on the left side and another PSU to power plugs on the right side. You CANNOT have both PSU's feeding the same side. If you do they will fight each other and very quickly either 1 will be destroyed or worse, you will damage the PMU cards that the power supplies plug into.
Aside from that, you can power just 1 side at a time to check it out.

Hi friends, I had a question about avalon 851. First, what is the way to detect bad Hashboard on avalon boards? Because these boards are in the status of vcc and gnd shorts now and they cannot be turned on. It turns on and the light turns green, but because it is a short, it give amper from the power supply boards, which damage the power supplies
