BitMaxz, definitely the same errors. So I detached the board 1 cable from the hashboard and plugged the cable that usually runs hashboard 3 into hasboard 1. I didn't switch controller board cable positions from 3 to 1, just plugged 3 into hashboard 1. Same result.

Thanks wndsnb, Super insightful as always. How hard would it be to self replace this part? Where would I get the part from? If I can replace the PIC microprocessor then in theory I could use the pickit to flash back on.

Block halving is coming.

This sometimes happens if the control board and hashboard have a bad connection.

Can you try to replace the cable or use the cable from hashboard 3 then test it again.

Just read the 3rd response from him which is solved by replacing the cable.

The error messages from chain 0 are from not getting any response from the pic microprocessor on the hashboard. This is a pretty basic function, the board only needs power supplied from the control board and a functional pic to get a response. Without the pic, the control board can't turn on the power to the ASIC chips, so there is no chance of getting anything working. Could be that the pic got fried and needs to be replaced.

Well got the S17 Pro back and was able to put eyes on the kernel myself. It went in for repairs limping and came out even worse, so I was hoping there might be a magic (sorcery will do too) recommendation to save this on my own with tools and hardware online. Boards are non-existent so any help is appreciated. Board 3 is off for now because it arrived with a loose heat sink. Board 2 is hashing well. Board 1 is the current issue.

1st Diagnosis - Tested all 3 hashboards, All ASICs report correctly with all temp sensors failing.

2nd Diagnosis and Final Repair. (Below)

Hashboard 1 (Chain 0)-
Temp sensors 2 & 4 replaced.
Reflowed Chips
Boost circuit failed board is unrepairable.

Thanks for taking a look!
