My S9K stopped working after I cleaned them...

[Wegatta]

Has anyone had the same problem cleaning you s9 and then they stop working?

What should I look for or do to get them back up and running.

I forgot to add that there are 20 of them and I have only tested 9 and only 2 of the nine are working. They show up and say Normal but just don't hash or even recognize the boards

[_oh_no_stop_this_]

Did you clean them with hot or cold water?

Next time clean it with compressed air and IPA 99%.

You have made some major fuckup while cleaning them.
I hope you only used IPA and compressed air?

Using things like water, soap water or vacuum cleaner will guarantee a bad result

Or it might be a connection issue between the hashboard and control board.
Try to clean them again and check all connectors and sockets and maybe they have full of rust and dust.

  I'm not going to do that it's very bad for electronic parts of the miner and it would end up short circuit or parts missing.

This devices work with high temperature.
The solderings are made with lead-free soldering paste, and are verry breakable.
Just the phisical manipulation of the board can cause detachament of one ore more chips.
The only solution is cleaning inside the casse with copressed air, and whe they are at normal temperature.
Otherwise you wil cause temperature stress.

If the chips get loose, unfortunatly you must resolder, or change, in any case you need special equipment and skils!
