I have been using a tester that I bought to find out which chips are faulty from the Hashboard S9. But it turns out that the controller was damaged. The controller is from a V9 machine, I have a replacement but when I put the SD card to do the test I get no results. I would like to know if I have to do something else, Flash it?

If someone also knows how to repair the controller it would be helpful

If someone can tell me if it is possible to repair a Hashboard without the need for that tester but using another method, I would also appreciate it

If someone has knowledge of Hashboard repair and is willing to offer a course, paid or free, I'm also interested. Since I have not managed to repair a Hashboard even following the manua

Been along time since I did any repairs but should still be similar to the the S7 if the device is booting and running then its unlikely its a controller. If its bad chips on the haphazard there usually easy to spot especially if there under there own heat sinks like the older miners as when you mine the chips usually stay cold or very hot so just work along the rows with a thermometer or by touching the heat sink.

Controllers from bitmain are a bit trickier last time I checked each one needs flash e.g a S7 needs to refresh to an S6 for it to work properly or detect the board.

How it helps ill have a poke around the net see if its still the same
