working 2 and 3 - Page 005

Great. Thank you.

good luck to you!

🙂

are you interested in the tester or repair manual?

Nice work 👍 do you have it for the s19 also ?

Do you have AR tester repair manual?

everything works the same throughout Bitmine

Great 👍

there may be problems with the characters in the password or the network name, we recommend using only letters and numbers. Unfortunately, we cannot change this, this is a limitation in the functions of the operating system kernel.

Sure I will do that thanks

We have many ARC tester here, we sometimes have problems with them

What is the problem ARC tester

Sometimes it's the red button that is not working, sometimes it doesn't recognize boards, sometimes its something else, general tester hardware problem

right now we don't have a complete repair manual, but we'll get to it soon. Thank you for your feedback!

But having tester maintenance/repair manual, with good values of the components and circuit, would be useful

Open your tester

Most of the time the buttons are simply used up, so we swap them with other boards that we have that are not working anymore.

But those ones that aren't working, it would be nice to have a maintenance guide so we can rescue some of them

we should have done the manual a long time ago, something went wrong…

Can you open the tester take the photo and send me

No need to send pictures for now, we're good, we have many testers so we're not stuck on a particular problem.

It was mainly about asking for specific maintenance guide for testers, so we can repair the ones that are broken/non-usable

If you send me the photo I gave good solution……

As said, I'm good. I asked for ARC maintenance guide, not for help of any kind.

And I guess ARC knows their product slightly better than you do

Ok no problem

I also have a tester with a bad button. Are replacements sold anywhere?

Does anyone know how to solve this pic control error? Have tried reprogramming the PIC and EEPROM, replacing pic chip, reflowing the area. The PIC does have 3.3v power, and there doesn’t seem to be any shorts, so I’m very confused

Most of the time it's the connection between the tester and the board.
Try to restart (unplug the power of the tester and then plug it back) and then plug it back to the board.

Otherwise, try with another cable

Unfortunately it’s consistent the hashboard doesn’t work in a miner either

Hi! problems with only one board?

Hey guys, someone has been through this before? Whatever board I connect to the tester, it enters a reboot loop

As @leovesque said We’ve updated the tester and now every board we plug cause the ARC to go in a reboot loop, It just keeps rebooting over and over until we disconnect the board.

"try 1/1 to get lic" means license ?

Greetings! This inscription informs that the tester is trying to get a license from the server, after receiving it, the logo appears and the tester starts working.

Ok, what you guys have to do to the license get in touch with your server ? Because looks like there is no comunication with the license and/with your server....

@leovesque said he figured out the problem, didn't he? Do you work together?

One second....

Hi again, there was some confusion on our side

So do we have any issues yet ? Or its working 100% ? Pls share de feedback after the tests.

I am sure that yes, it is extremely likely

Yes

Im just waiting Leonardo finishing the tests.....

do you have a circuit board? will she help you?

We let you guys know in a minute.

there is no reason to hurry anywhere, the main thing is that the problem would be solved!

Circuit board? Sorry I don’t understand what you mean

service manual

hi 2 all. we got new 19j. & new chips in it. bm1362 but they r smaller then ordinary chips))

Bitmain has gone crazy

& no transistor in power line on hb

S19a & s19+ has chips incompatible by pinout with the rest of the 19 series

i met j 110t with chips powered by 1?3volts - 10 domens

hi i want uograde my tester to pro version

Hello! I have answered you in whats app. Check please.

Hello
Whenever I want to test if temp sensors are ok in T17e and S17e this happens. All ASICS are recognized but when I click for temp to read temp sensors it suddenly show 0 ASICS and stops.

Any idea to fix this ?

do ri short on half board before test start and then do temperature test

Quick question:

the stencil is the same, but the pinout is different

Do you know the pinout ?

they seem to be in the manuals

What's in the manual is the logical representation, not the physical package representation.

Oh, man, these things are all kept secret

Thank you

hi, tell me, please, how many volts and amps do you supply to the board and what kind of power supply do you have?

On that note, on an S17+ board, supplying 14V ended up frying the boost converter circuit on one of the boards - the L1 coil couldn't handle the undervoltage

Thanks for the tip ! Will do that

Means one of the chips is not hashing. Check the RI signal, it will turn to 0.8v at the problem

The boost PWM can work from 14 volts, this is not a problem for him, he just was faulty.

I already have arc l3 and s9 model can upgrade to pro version ?

Power supply is a KIPRIM DC310S. Supplying 19V, Max Current is 10A

I just realized that it show 0 asic because due to high demand of current (more than 10A) voltage decrease.

What power supply do you recommend ?

Is there a way to manual set 18V on the original APW9+ ?

Hi! We use Uniontest 6015, you can trust this manufacturer. There are many power supplies that, at the stated 20 amps, give out 5. You also need good wires, otherwise there will be a large voltage drop on the wires.

Thabks

Does anyone know what this port is used for?

I would guess it's Arcs port to troubleshoot or program the testers

The board fails under load, try to cool the board in the freezer and test in the tester.

Can you show the log with vnish firmware?

Tried that many times !!

Try hiveos

Bonsoir
Y’a t´il des français sur ce groupe ?

Oui plusieurs français sur le groupe

Salut Anthony :)
Tu répares les antminer ?

Oui je t'écris en privé

Je propose de payer quelqu’un pour qu’il vienne une semaine

Thanks Javier ! I will try that tomorrow :)

👍

which power supply do you use to power the board?

Salut Farouk 😁

Salut Aurelien ça va?

Impec 👌

🤣👍👍

hey guys, has anyone ever seen a board show only a few chips good and then after running for a minute, the board shows 48 chips, and then drops back to some working chips for a second, then go back to 48 good chips randomly on an S17 board?

Typical behavior of the 17 series. As many have already mentioned here, a complete reflow of the board will bring stability to the diagnostic. It is possible that these are microfractures or a cold solder joint. Also it happens that the tin on the top of the chips "slips" on the sides and create small balls of tin which lodge in the contacts of the chips, so a complete cleaning is necessary before reflowing these hashboards.

thanks man, we have been reflowing these boards by the dozen, with great results. I've never seen a board do this before haha.

What procedure are you guys doing for reflowing? Do you use an specific hardware for reflowing or just bake it on the kitchen oven? 🤣

legit have a regular kitchen oven and a small convection oven from walmart. lol throw the whole board in @450 degrees farenhieght for 10 minutes and let them cool, and your good to go.

Tks mate, we’re having some boards presenting this kinds of weird behavior too, so I will try this for sure

I personally haven't gotten that in depth with the temperature measurement, but I suppose it wouldn't hurt anything

What is this error? S17 board

you have damaged the contents of the EEPROM, flash it.

hi guys.who can tell me how to determine what kind of chip should i buy 4 my wm m30s? seller sugests me KF1960 (3C / 3G / 10C / 10G/ 15C) but (3C / 3G / 10C / 10G/ 15C r very important but i dont know which 1 in my wm

I see this very often, it doesn’t necessary mean that the EEPROM is bad or corrupted, just the arc doesn’t recognize it. Manual set on the ARC the model of the board and it should be ok ! If after fixing the board it shows eeprom errors while mining, flashing is highly recommended!

Hello we are ready to repair the tests for if someone need we have a workshop in brazil and also in paraguay. Just text to me

Finally made it

Try unplugging and cleaning the IO port of tester. Inspect wire ends to see if dirty and clean as well. You can also swap IO cable as they tend to break inside over time. If nothing else works, your tester might have a fuse issue, easy to fix but I'll let ARC assist you with that if it is the case.

Done all of those

Most likely fuse then in my experience

Replaced fuse, even tho it worked before

& other hashboards have the same behaviour or just this one?

All have similar

Try changing fuse again, but test after with a working board. It is possible you fried the new fuse with the same faulty HB after

Voltage is fine after fuse

Doe you have fuse data?

I believe this is the one, 1A

hi! Please make measurements as in the document, it will be easier for us to help you

do you have any other manuals?

manuals about what?

For the arc
