Hi. Recently, one board of my antminer s5 died. The red led on the board won't turn on, and it's cold. Shows up as ----------- on the miner config. I wonder if that's a situation that could be fixed by a reflow?. And, does anyone know what to expect/what to measure on the PCB test points?, like the expected core voltages and so on. Thanks.

Checking core voltage should give you an idea. My dead board has things all over the place, from proper 0.6x volt to 30mV. From how to repair this, i don't know if its doable, its pretty hard. (Maybe RichBC can reply to this in less noob terms)

If its really dead and you tried a different psu, swapping the controller of sides and such, then you don't really risk much doing a reflow, its not impossible that it will bring it back alive, but it did not work for me.
