Antminer S17 has no hash rate or cannot be started. This may be caused by changes in the internal data of the hash board. The internal data of the three hash boards must be consistent for the miners to work normally. At present, there is a solution for the failure of mixed use of hash boards or abnormal internal data, which can be completed with only a small device, which is developed by ZeusMining, website: www.zeusbtc.com

Heatsinks on these miners are not attached using adhesive. Instead, the heatsinks are soldered directly to the top of the chips with low-temperature melting point solder (138 deg C). Using thermal adhesive to attach the heat sink to the chip may work, but it might be extremely difficult or impossible to remove it once it's on.

Started work on the 1st S17 from my host. 2 hashboards showing 0 chips. Turns out both of them have heatsinks that are misaligned enough to short to the adjacent row.

After moving this heatsink back into position, this board comes up and identifies all chips, but the test fixture is showing a couple of bad chips so it looks like I'll need to replace a few.

The 2nd board is still not coming up after moving heatsinks back into position. Looks like an issue with the pic microcontroller on the board not enabling power so I ordered a pic ISD (pickit 4) to investigate that further. Hoping that Bitmain did not set the read protection on the pic flash so I can read out the firmware to be able to program a replacement chip if necessary, but I'm thinking chances of that are close to 0. If not, it looks like zeusbtc sells a download for pic firmware for all Bitmain's miners.

Also, just another thing I noticed with both these hashboards was that there were insect wings (looked like moth wings) blocking a few of the input side of the heatsinks. Could be what caused some chips to overheat enough for the heatsinks to slip. The solder holding the heatsinks on is low-temperature solder, so it will melt at under 150deg C.
