I've been trying to repair this s17e i bought of alibaba.

I managed to take it apart and reconnect the ribbon cables and even do some re-soldering around the ribbon connections.

The middle hashboard is not hashing, it appears to pick up all 135 asic chips but it says bad voltages or no temp sensor?

Here's the log. please any help would be much much appreciated.
