S9i hashboard chip numbers

Hello everyone.
Recently i got an S9i hashboard which i tested with my text fixture and it was working fine. So, i replaced all the heatsinks with smaller ones. After that i test it again with my text fixture and it says Check chain = asicnum=30. My questions is which one is the 30 or if the 30 one got a problem somehow.

.
In both cases i tested resistances and voltages in every chip of that line and its the recommended ones.
Thanks for your time.

Did you read the manual carefully?
Use the signal there are 5 test points to check also check the back part all Asics is on the back your image is only showing heatsinks and test point. all Asics chips are on the back with a heat sink.
Here's another diagram this diagram

This is how chips are numbered.
https://www.imagebam.com/view/ME8IINC
If see only 30 chips the problem can be:
Chip 30 - not weldet good
Chip 31 - broken or not weldet good
LDO voltage of domain with chips 31,32,33.
Check 5 test ponts voltage with test tool.
Why you changed heatsinks?!?!
