hi guys my first post just bought 2 strongu u6's and got a innsilicon t3h 50t s1 thrown in the deal cheap, the guy i bought it off bought it but never got it working. he replaced the psu but still nothin. it fires up fine gets ip and such. upon startup the hash board lights go green then after 20 secs or so the fans go into overdrive and the hash board lights go off. then it never gets any further in the autotuning (presumably as the hash boards get knocked off by the fans over powering at a guess?)  on the innsilicon page it just cycles round and round trying to autotune but not getting anywhere. any ideas would be great im thinking poss fan problems ? im new to this and this is my first post so be kind... ;D thanks

you need 210-240 volts for the psu.

try going to autotune and set to low speed say eco or eco+

see if it will work on low speed setting.

if you have low speed set and you have a good pool and 210-240 volts.

psu should fire the boards up.

sometimes psu is weak and the low speed setting works.

other ways to trouble shoot pull one board put it aside and run two boards on low speed.

if it works try balanced speed.
if it works try factory speed.

if it does not work pull second board.

run 1 board on eco
if it works run on balanced
if it works run on factory.

if one board does not work try second empty control cable.
does not work tried third empty control cable.

if all that does not work pull the board put it aside.  repeat with next board.

you may still be dead.

put it aside go to third board.

if each and every board fails when used singlehanded.  you cant test much more.

Could be dead hashboards. Or corrupted firmware. Or faulty control board. Or some dead sensors. Actually, it could be anything... Try reading Kernel Log or whatever innosilicon calls it. There should be more info.

And try what Phil recommend. Especially if you are located in 110v country.

thaks for replying... tried that i set to economy and it did save the settings but no difference.

i wrote more.  bottom line is you cant know for sure unless you have a good unit and swap parts.

if you only have 1 unit.

if you have 210-240 volts.

pull two boards test one board in all three spots on low.

test each and every board this way.

that is nine tests.

if it all fails and you live in the 🇺🇸 usa 🇺🇸  you can ship the unit to me .  i have a fully working unit.  i can test your parts by swapping them into my miner.

Tried all that.  No joy.. when I unplug the boards and fire it up the green light on board stays on indefinitely.  If I plug a board in (any board or cable tried all variations) itll stay on for a minute or so then go off both on socket and board. The green lights on the other two board sockets stay green though. Was looking into ssh control with minerstat but given up for tonight boo hoo.

Do you have Inno monitor ? It will tell you the error code and with that I can tell you whats wrong.

I repair t3h 50t all day long. That kind of problem can be the control board not the power supply. Or that the SPI on the hash board fail.

hi sorry for the delay been mega busy this end. got a error code 30  . any ideas would much greatly appreciated
type t3h+
mode factory
errcode 30
factory empty
psu vendor gp
psu version 7.69
psu fault 128
total hask 0.00ths
accept rate empty
hash #1 o.ooth
temps 0/0/0
standby false
network dhcp
runtime 00d00h00m00s
firmware tsh=_soc_20191207_030444

hope that makes more sense to you than me haha

Correct me if I am wrong but isn't error 30 something related to firmware?

Otherwise, if I am wrong about that one, then I assume it would be PSU fault that miner is not working.

In your place, I'd contact Innosilicon and tell them everything you know.

I have contacted inno tbf they're being very helpful I'm just waiting on a response.  I had updated the firmware and factory reset to no avail

Did you ever confirm your voltage? I'd start with FW, easiest to rule out with a single unit.

Sticker on your unit should give model letter.

Error 30 is that the connection to your pool as been interrupt. Maybe a problem with your address. Most of the time for me this error appear with i start a T3h for the first time but it goes away after like 10 min of running.

Yeah, this was usual on some S9s in our country as well. It sometimes took between 15 and 30 minutes to power on and start mining. Have you tried waiting @faz27?

hi guys just an update i know its been a while.. believe it or not im still waiting for a new control board from china. they posted it weeks ago but the virus hit around same time so been about 6 7 weeks now. lol

Yea, Innosilicon is based in Wuhan. . .

hi guys update, my new control board arrived.. put it in... fired it up... exact same thing. gonna look at testing the voltage but the error code still says 30 which innosilicon said was pool issue. ive tried nicehash slushpool f2pool and a few that they recommend. all same. ive messaged innosilicon and waiting for response.

I have been following the thread and waiting for you to update since the previous owner replaced the PSU and you replaced the control board, it's all now pointing to faulty hashboards, this is a very rare case, we don't know the history of this gear, the other guy might have bought it used from a reseller who purposely attached dead boards and shipped it away.

but before giving up on this, I want you to try different network settings, by different I mean EVERYTHING different from the network cable to the router and even ISP if possible, and would you please post the pool settings you use? just in case you are making a mistake here or there.

mikeywith sorry can you email me haggislover1 [at] hotmail [dot] co [dot] uk only one message per hour apparently.
