yes patch - Page 003

I cannot start test , because when test is on show that msg
Normally when test is on and we plug some board , test show me s9 or s19 … and now I plug nothing happens ,

Whats the serial number of the tester? You can find it on the back of it

Remote access to your pc wont give me anything useful

Yes like I told you
I don’t need plug nothing to take that eprom error in red

Wait a minute, you've got that error even without the board connected to the tester?

Yes

Perform the measurements as described in this file and send them to us

Ok I will ask thanks

have to exchange epron

Hi do you have a solution when there is 0 chips found but all signals are good?

Oven, 450 degrees for 10 minutes

Trace your RO/RX and check where the voltage dropped and also check 0v8 and 1v8 but the problem is most likely broken RO/RX it’s 1.8v running from the last chip to the first chip

Rx is 1.8v to all chips

Hello, anybody know what the voltage should I set for the T17+?

I have a question guys, does anyone know how to solve temperature for s19 pro?? Thanks!

What do you mean by temperature?

Well it says in the miner log. “Temperature exceeds max temp, kill all hashboard” is it because the temp sensors are broken? All fans are good though

Well, usually if the sensor are not working it would give an PIC error in the log … if it does not appears in the log then the sensor are ok and the temperature is high of the room if you are using air cooling

Thank you! It does that “fail to read pic temp for chain 1” and “pic read iic failed ” we can conclude that this is a sensor problem right ?

Yes … then let me give the common problems

Does s19 pro uses the same temp sensor as s17+ (t451) ? Is it also on the back of the board ?

No, sensor is TMP75

Wow, they have actually changed it. Thank you very much Meshal really appreciate it !👍👍

Usually if you have a PIC problem then the cause one of the following:

1. tmp sensor failure, and can be solved by replace the TMP sensor (most common the inlet sensor)

2. Resistors and capacitor connected to TMP sensor (missed or damaged). This is solved by replacing them

3. Track between the sensors, tracks might be rusted or damaged. Can use multimeter to check the connection between them pin1 in TMP1 should be connected to pin1 in TMP2 then pin1 in TMP3 and filing Pin1 in TMP4. Do the same Pin2, Pin4 and Pin8

Amazing !! Thank you so much !! I wish your message could be pinned so that more people could see it !! Fantastic !!

Your more than welcome I happy that these was useful

Thank you so much dude !!! Really appreciate it, you have been such a tremendous help !!

Your more than welcome

Got it thank you very much Meshal really appreciate it!!!👍👍👍

hi which line hold temp signal in 17+ antminer

Do you mean the pin of the chip or the physical location of the temp sensor on the board ?

no the line like Ro Ci
which line ?

I have a further question, so I found the temp sensor on s19 pro, but on all s19 pro boards 4 of the resistors that attached to U8 temp sensor 2 are 100 ohms and other 2 are 4.7k ohms 😓

these lines go to sensor but temperature must go to pic
which line hold signal to pic

Oh I see what you mean ! It should be RO but I am not sure 😅

thanks for helping 👍

I am not sure though , hopefully someone else could give you a more definite answer sorry😓

🤗

I do not know what you mean 100 ohm … if we take U8 for example … pin1 is connected to R215(4.7 Kohm) and pin2 connected to R214(4.7 Kohm)

Thank you Sorry I made a mistake there 😅😅

No worries 😉

Perfectly, thank you very much you are awesome dude👍👍

Yes, now it works

Why I need flash eprom every time I connect board?

Hi, whats the serial number of your unit, whats the fw version?

What is the problem I don’t know

607, 1.34

Please, update to the latest version (1.341)

Already I update version 1.341

Reboot the tester, then refresh the page with cache clearing (Cntrl + F5)

What is not working? I'm telling Aleksandr to update to fix his issue

No

Whats wrong? its first time i try to repair Wats

Please can you update the L3+. Regardless of the data cable I use, the tester picks up no chips, even though the 6 boards I tried it on are working perfectly.

Please update your taster 1.341 version

Hello i use the tool, but can we get some more info on which chip to change ? If i have number 3 in red for exemple on a T17 ?

Hello does anyone here knows a good source for learning a teaching repairing Bitmain s19 miners. Compared to the s17 repair information for s19 is rare

Hello ! If you have asic 3 in red, it means that the programmer is telling you that the signal is even there. Logically you would have to change the asic 4, of course, you would have to check signals before determining a change of asic .. visually check if it has the resistance, or if it does not have any trace of tin stuck by the asic 3 or 4.

Thanks 🙏

Hello guys I have a question about m20s we. I don’t have TXD voltage at U6 after multiple chip swaps. I have RST, CLK, and RXD all the way through U1->U105. Fixture still says RST fail and check power😓

Check level convert also

👍 professor

Thank you, could you elaborate a bit more ?

30 chip RI/RO? Sorry, from Russia

Ooou. Stop. What is mainer?

T17

Look RI in test point

I change all mosfet and it’s work

Small 6 pin ic on right conner of card

Replace Pic, eeprom and Transceivers

Thank you very much Amnart ! But if I have RST and CLK coming out of U6 then it would mean that my voltage circuit is correct right ? It is just the TXD that is abnormal.

Guys, What does x19jx mean ??

Is it some sort of error?

Bitmain is constantly changing the structure and method of encryption of EEPROM, you have come across a board with a type of EEPROM unknown to the tester, please save the dump and throw it here, we will add it to the tester and everything will work.

Hello, thank you very much !! I will do that 👍

Sorry ARC, I have a follow up question, could you point me to a tutorial where I can find how to save and port out the dump file from the fixture ?? Thank you so much !!

tell me the serial number of the tester please

Hello guys I’m new to this channel.
I have replaced this button because it wasn’t making proper contact.

Do you using original psu ?

On the tester or on the asic ?

Tester

I bought the power supply at Amazon

Try 21, becasue miner start with this voltage

Ok
Thank do the advice !

Has to be psu or control board or flatcable connection . Switch them to see if there is any difference

Thanks
Will try that tomorrow!

@ARC the serial number of my tester is 10000865 could you please walk me through the steps please ? Thank you !!

Hi, just connect the board to the tester, go to the "EEPROm edit" tab in web interface and press "Download EEPROM file" in the upper right corner of the window

Hello, does the ARC support S19+ 99T ?

Thank you will try that today !

could someone give me a dump m31s of 105 chip

Our engineer will take a look at it, we'll get back asap

Thank you very much ! Really appreciate it!!

Does anyone repair the APW12 PSU ?

Hello good morning !! Could anyone tell me why my Asic repair used to give me bad chips and now even good hashboards give me 0 asics?

Hi, whats the serial number of your unit? What fw version it is running right now?

Serial number 10000728
Versión. 1.341

Do you have a problem with a particular board model or is it all the boards that you receive 0 asics?

Do i need to power the hash board, with this unit to detect bad or good chips? Specifically the Whatsminer Unit

Of course, no voltage, no asics

ok can i use the PSU form the unit itself? or do i need to buy something more? links preferred so i can send to purchasing, thank you, sorry i am a noob at this type of repairs

Watch this video 😉 https://youtu.be/woDjyVGhrn0

Hello Arc ! I was wondering if there were any updates in regards to the dump file I uploaded yesterday for my s19 board ? Thank you !

With all of them at this time, both from L3 T17 S19 and the S9 before, if it detected me, but it has been about 3 days since they all started to mark 0asic, even when the chips work.

We will reach out to you as soon as we have any info on it

1 of 65 Asics is Bad, short 1,8 and RO signal and find bad asic. One asic chip gives -1 chip error, so for example when you short chip 30 and tester show 29 and when you short chip 29 and found 29chips, 30chip IS bad

If it's ok I'll try it to see how it works

Thank u

Ok thank you !

I got some problm

Hi, press the model selector knob and turn it while pushed in
