İts definitely no pic board. As I already mentioned, it was working fine before. If I could manage to get the board detected, I would completely disable the voltage to that chip. I'm following the instructions on BrainOS, but I still haven’t succeeded. I access the miner through the command line using ssh root@miner.ip, but commands like cd /etc from the guide don’t work — I’m wondering if it’s because I’m using Windows? Also, I’m curious: if I manage to supply voltage to the board, will the chips and frequencies appear in the software?

Hello. I recently purchased a new S19k Pro. I used it without any issues with the original firmware for the first two days. Then I installed the VNish firmware and it worked fine for about three more days. One evening, I shut it down, and the next day when I turned it back on, the machine didn’t work. There was an error on one of the hashboards. VNish reported an error saying that on Hashboard 3, 76 out of 77 chips were found. I read that no-pic miners operate this way on faulty hashboards. When I disconnected the faulty hashboard, the remaining two worked without any problems.

Then I thought maybe BrainOS would work, so I installed it. However, BrainOS gave the following error:

Tuner error: disabled hasboard 3 (hb3) (errl1) unexpected revision of chip 0 ( expected 0x1366 received:0x1346 )

I1 error: wrong hashchip revision for this model
Hint: the chips either sent garbage( temporary error), or the hashboard is npt supported , or the hasboard was misidentified by bosminer. Try to restart the miner.try to replace the hasboard.

When I removed the board and checked, there was no visible physical damage. And according to BrainOS, this chip is not compatible. But if it's not compatible, how did it work previously? Unfortunately, there’s no one in Turkey who repairs hashboards.

I heard that BrainOS has a setting that bypasses this error and continues supplying voltage to the board. If I enable that setting, could the hashboard continue to operate with the remaining functional chips? What do you suggest i do?
