So if your diagnosis is right, it seems there is a serious hardware error.
I was hoping there wasn't (like some loose cable on the PSU or something).
In that case I suppose sending it in for repair and hoping for the best is the smartest move. Huh

Putting it on the side actually did work for me before. I read about this somewhere in this forum. Tried it again today, this time without success.

The nature of my project does not allow for constant electricity supply. I do have free electricity from time to time, but at other times its rather expensive. The miner is supposed to be installed inside the tower of a windmill.

Thats why I am coding a control software that will tell my miner what to do, based on the current price of electricity (if selling the energy is more profitable I won't mine). By my calculations it will be able to run profitable about 70% of the time though, which should result in profit long term.

Regarding your tips:
1. time saving is not important right now. This is a research project and I need a functioning S17+ to do proper research. Profitability is not relevant (yet).
2. I am running BraiinsOS on all our S9s (12 in total). It has not released yet for S17+ (but will be this year). I am planning to use it for this S17+

I have also tried Awesome Miner Firmware. It has the same issues (missing hashchain).
Setting a low power profile did not resolve this.

It is a serious problem, and as I said, there is not much you can do to fix it unless you are well versed in repairing them.

Bitmain will never take only one hashboard for repair, you will have to send a whole unit (might be expensive due to shipping across half the world - assuming you are from USA). Also, if you decide to go through with only sending one hashboard to your reseller, be careful not to send that unit to Bitmain as I think they will count it as voided warranty if all three hashboards are not from same miner.

It matters on which side you put it. Big heatsinks should be on top as they are usually the ones that are loose.

Good luck with your project, report here in new thread when you finish it and if you are up for sharing it.

Try Thierry's or Taserz's firmware, I highly recommend both. First one has lesser fees but less features, second one has higher fees but a lot of features (you might find useful).
