The hashboards require service, it's likely a burnt boost circuit or faulty asics that need replaced or reheated on a hot plate. You can consolidate units together if the boards are matching version. We have spare working 1246 hashboards if you need a few

You will have a short profitability window with any alt miners. Scrypt Asics are generally a good buy, would recommend the Antminer L9's as the next halving for LTC won't be for another 3 yrs. November and December batches are also way cheaper. The L7 was released in 2021 and is still profitable today. Also, S21 pro or Whatsminer M60 not bad options

There are individual heatsinks for each chip that are surface soldered on the way that the S17 models were designed. The missing ASIC chip error may simply be a bad solder joint opening up as the board expands from heat and a loss of communication occurs. Also, a chance you have solder balls somewhere or a bad ASIC chip. Unfortunately, no easy way to find the cause. We have spares available for sale depending if you have aluminum or fiberglass version hashboards

Same experience, the most recent batches being the worst that are all aluminum substrate hashboards. Bitmain regressed back to the S17 nightmare design. Even after repairing them the poor quality solder can cause problems like intermittency from cold solder joints all over the board that may be barely disconnected. The initial release batches that are fiberglass backed still run well in immersion

Would recommend S21s or Whatsminer M60s. Mining BTC is going to be the most predictable long-term

2000 for a S19j is pricey in the current market. We have used 95th model available for 850USD

Not very profitable since the Eth merge. You could swap hashboards to get as many working miners as you can but it won't be economically viable to repair them.

There is a hashboard issue with Chain 2 reporting 0 ASIC. The "pic read" error likely doesn't have anything to do with the pic but rather the temperature sensor(s) that are failing to read or unstable chips.
