man ive got 2 units doing the same thing (one board on each unit gone and log shows 0 asics)

i had this issue a few weeks ago on another board and I sent it to the US facility and got it back repaired.. but now a different board is gone on each unit LOL

and the board I got sent back has missing o's ( 9 to be exact) so instead of like

oooooooo oooooooo
it shows
oooooooo oooo

great repair service Roll Eyes

.. so now ill attempt to send the hash boards that are now disapearing and see what happens.. not sure if i should send back the one with missing chips AGAIN

geeze...that sucks. Was it Bitmainwarranty.com that you sent it to? Also, did you go through Bitmain's ticket/support system and then they told you to ship it there, or you just paid to have the US facility fix it since shipping to and from China would take too long?

I had the same issue and it's really annoying! But I was able to solve it somehow by setting this board to higher voltage settings - and I finally got rid of the problem.
I know it's not the best solution but it helps and if you're lucky it'll last a while...

what voltage did you up it to? so basically in blisz firmware you selected that board and only upped voltage on that one? and it came back from being disappeared ?

yes, with blissz fw I set voltage (this one board only) to >bitmain default - I think it was 15 or 16. This means gently overvolting this board, but it won't do any harm as long long as frequency and temp stays low. So I startet with freq 425 and went up a little.
It's up to you - but I'd try to set the voltage a little higher as usual and see if all ASICs come up again. It was the case in my situation.
Usually I used blissz fw to undervolt - but in this case it worked for me to do the opposite...
