1  Economy / Service Discussion / T9+ hash board repair or replacement? on: April 14, 2018, 03:25:47 AM
Hey there, I'm back.  I'm still having the problem as noted below and have determined that the "middle" hash board is bad.  I've contacted Eastshore and they have approved sending the unit back for warranty repair but as a hobbyist (yes, I only have one miner) I'm thinking sending it back is more trouble than it is worth.  I asked if they could send me a hash board and their answer was no.  My question is if there is a place to buy a replacement hash board or to get it repaired?  Otherwise I'm thinking of selling, someone out there may want it for parts.  In the meantime it is hashing away at 7 Th/s on 220 volts!!

Thanks  Smiley

I gave that a shot and did a variety of combinations of swapping control cables along with powering just 2 of the 3 boards and in all cases the middle board never worked.  One location is always missing and the other two read 0.  When I don't power the middle board all of the remaining 6 locations work just fine.  I've sent a note to Eastshore, hopefully getting the fix will be straightforward as I've read not so good reports about sending the unit back to China. 

Thanks for your help and patience with this new miner, it is greatly appreciated.

Yes, thanks.  I checked voltages quite a bit over the last few days and am getting good, stable voltage the the power supply and it is putting out consistent power.

It looks to me that the middle board is not working as every variation of cables, powered/non powered tests, etc. point to that.  Can I swap the boards the controller ribbons go to? In other words, can I take the middle controller and connect it to the first board, etc. so if it is a controller problem the problem would go to the new board.

Ok, I gave it another go on 240V, (actually reads 248 v and stable).  I did a baseline run, no changes, same result as before, 3 is missing and 11 and 12 read zero.  I reset the T9+ per Eastshore's recommendation, no change.  I then ran it with each of one board's power removed; once with board 1 removed, board 2 removed then board 3 removed.  In every case 3 was missing and 11 and 12 read zero unless they were missing.  Interestingly when the middle board's power was removed exactly 3, 11 and 12 were missing and all of the other chains had readings:

2nd board power removed:

It looks to me like board 2 consists of 3, 11 and 12 and it appears bad to me.  I have not reloaded the firmware yet, probably the next thing to do but I'm not thinking that is the issue...

Thoughts?

Thanks Yrth and all for your advice.  Ok, now I'm really frustrated.  I wired this up to 240 volts and am getting pretty much what I had at 120 volts.  For the first day on 120 volts it worked well but has been like this since I moved it.  I put it back in the original location, still on 120 v, no change.  I have moved the power cables around and it doesn't change anything.  Now on 240 v I'm getting this:

I've contacted Eastshore but haven't heard back from them yet.  I'm open to suggestions but I don't have access to another power supply at the moment.  

Huh

Could be.  I moved the T9+ back to its original location but didn't change anything else (all power supply connections are the same) and am currently getting this:

I will try and change some of the power connections (from the PS to the miner) and see if that changes anything.  If no improvement after that then will try 220V.

Edit:  I tried changing power supply to miner connections around to no improvement, Chain #12 remains at 0.  Will try 220 now...

Thanks!

Are you running it on 110v or 220v?

I'm using 110V.

Thanks for the feedback.  I'm going to put it back in its original location and see if that doesn't help.  I read somewhere that the power circuit (wall socket) needs to be able to handle the current so maybe that is it.

Yrth - I'm going to show my lack of understanding here but how did you determine that chain 3 was missing from the picture?  I see that 11 and 12 are reading 0 but the others look good.  I know I have a lot to learn but that is part of the fun isn't it.

Hey folks, new miner here but not new to BTC.  Recently received a new T9+ from Eastshore, fast shipping, etc. all looked good on arrival.  I also bought the Antminer APW3++ power supply as well.  Setup was fairly straightforward and I was mining soon after getting it all setup.  After 24 hours all was well, hashing about 10.5 th/s but I decided to move it to a more practical location.  After turning it back on the hash rate was significantly lower and after many hours searching the internet I've rebooted the unit, swapped power supply locations (same power supply, just swapped the connections around) and basically have not been able to get a different result. I'm getting about 7 th/s.  I'm open to suggestions.  Kinda bummed though, I was really excited about mining.
