It need experienced..
i have attended the repair course and i appreciate more to those technician after that class..

Sometimes the tester show certain ASIC malfunction, it is not that ASIC problem, but dry join for a resistor.

Enjoy

With this, miner still possible to be hacked?

May 2019 firmware will stop hashing when no fan detected or even will not boo upon detect low fan rpm.

Others firmware - not sure.

careful, i have done according to the web. Was working fine for few days. Can detect rpm etc.
Few days later Controller board not able to detect the rpm, checked it burned that specific signal. Not even can detect 12cm fan anymore.

Just sharing my experience only. It could be i have done something not right.

Dear All,

I have connected the USB to serial converter to the S9 controller board. Connected via serial connection and got bunch of messages.
Weird is i cannot login, and the system just continue to reboot n ended at Fan detection.

What ever i type seems not received by the Controller board.

Appreciate kind advise.

regards,

MM

I encountered quite same problem but with L3+

when i installed the 4th hash board, the hashing rate (RT) will slowly decreased to 0.
Changed everything n lastly found the controller board having problem.

In detail what causing the Controller board behaving like this unknown; as i never bother to send for repair due to cost.

 Grin

MM

Hi Technak,

Do you think reinstall bitmain firmware using SSH will enable back "SD port"?

Anyway i can PM you please?

MM

Hi Technak,

Your write up is to enable SSH port for  firmware version may 2019.
May i know how you solve the issue of "2 led light up when changing the J4 jumper during SD card flashing" ?

thanks

MM
