and

so I switched 18pin cable connection 1and2 and still board1 is dead(this time board1 is chain2)

So please give me advise:-(

Same happened to me with two different A3s. Did you solve the problem?

Forum member Mr. Bliss help me out with firmware and I flashed it.
But Ohhh one hashboard is still dead 1st shows 3 ASIC alive but in few minute dead.
So My friend our BLADE came faulty.

All we have to do is now asking BITMAIN for treatment.

People with fine A3 congratulation for nice harvest .
Who are not let's do our best .
Peace out.

That looks a lot like a Power supply problem,

Try to unplug PCIE cables from boards 1/2 and chain 1/2 --> test board 3 (see if it works)

Then,
Try to unplug PCIE cables from boards 2/3 and chain 2/3 --> test board 1 (see if it works)
Then,
Try to unplug PCIE cables from boards 1/3 and chain 1/3 --> test board 2 (see if it works)

If they all three work then chances are it's a power supply issue.

Another thing, try to move the location to a different wall outlet and test it there that sometimes works for me.

Hi boneyg001,thanks for kind advice!
I did tried one blade test actually.
But testing order was different.
From config panel it says chain 1 is malfunctioning.
So I did chain 1 first.
And it didnt work.
Is that important the order you suggested?
Then I had better try it?

The power voltage is 1 phase 200V.
I tried 3psus 2x AWP++ and third party 1800w.
All worked fine with D3.(which I got rid of for this A3.)
So I think PSU is okay.

But one thing I wonder is when I reboot it.
When starting noises went down it shows miner status
And many times the number of ASIC is slightly different.
Sometimes chain 1 doesnt show at all .
Sometimes it shows 3asic alive then dead.
Sometimes it shows 6asics alive then dead.
Sometimes 4........
Strange, maybe something like coil on the board is attached loose.

Anyway at this moment disassemble myA3 now is risky about warranty issues.
I will wait for Bitmain reaction.
Hope it will be quick.

I am having this issue since 3 days. Tried different PSUs, changed the data cables, plugged one hashboard after the other and still not working....same story.

Do you think someone else archive of backup can help?
