This is basic miner repair 101.
-0 ASIC means:
A. there is an issue with the power supply somewhere on the board.
B. The answer or return signal (RO) from the last chip the first chip is interrupted by a bad ASIC or solder joint.
-Non-0 ASIC means you have it signal interruption going up from the first chip to the last chip. Which is composed of three lines:
A. 25Mhz clock signal(CLK)
B. A signal call reset(RST)
C. command data line(CO)
You don’t need a tester to probe these lines but it must be plugged in to the control board with power. All lines are 1.8 V +/- 0.05 V except for clock which can be anywhere between 0.8 and 1 V. A tester is just a fancy control board with an LCD, a button, and the ability to send a test block to the hashboard without a pool(we called that a PT2 test and requires active cooling as well as a high amperage power supply). These static signals always exist regardless of whether you have a test or not. There’s so much more to it, I suggest you read the excellent guide of the Zeus website.
Topic: Has 0 asics antminer S9 (Read 265 times)
To do this tests you need a hashboard tester ...
Hello, the display of "has 0 asic" needs to check whether the voltage of each voltage domain of your hash board is normal, this is the description of the S9 voltage domain:

If the voltage is normal, you need to check whether the RI signal is abnormal. Here are instructions for checking the S9's signal:

Hello,
What are the most common failures when the web interface says "has 0 asics" on an antminer S9?
This is not a firmware problem.
Thank you in advance.

The most common problem is one ore more chip's from a board are schort circuit.
The second, one ore more chips have bad soldering, this can be diagnosed by pushing gently the chip radiators with finger, the 'big' radiators, not the small ones.
The third, problem with power supply of each board.
It might be just a connection issue and maybe the ribbon cable is not properly plugged from the control board to the hashboard.
Try to replug all cables from PSU and ribbon cable and then try to check it again.
It would be better if you can post the whole kernel logs here and maybe there are other reasons why you get 0 ASICs on some hashboard.

I have cards that have less than 63 asics but show me the numbers and others that show me 0 asics.
A problem of asics is possible for those with 0?
