I sent the card in question to a friend so I don't have any logs, but I update as soon as I have a new error (I have the same one on another card)

Also on another card, I have all the chips in CLK at 0.9 but the RI signal breaks level 26 25 24. And is at 0 until chip 00.

I tested the LDO, they are well at 1.8v and functional. The capacitor 330u 2.5v also functional.

Where can this come from according to you ?

On this picture you have in grreen area CLK0.9 & RI 1.8 and in RED CLK 0.9 and RI at 0v

Sorry but it's hard to troubleshoot without the hashboard on hand.
And those signals you talking about are for ASIC chip not for sensor temp.

And also, I just want to you to try, and maybe it's only a software issue like I said above try to flash the unit with stock firmware from Bitmain and then try to flash the hashboard with a hex file that came from working hashboard.
If you don't know how to flash the hashboard check this link below.

And what I'd like you to check is the temp sensor checking them visually is not enough you need a working temp sensor if you have extra hashboard you can desolder the temp sensor to replace them. This is the way how I repair replacing the sensor with a known working one is my way to test them as according to your logs it's pointing to your temp sensor.

Please read figure 19 for the schematic and how to check them I already post the zeusbtc link above.
