Hello people,as i only found this thread usefull about spondoolies sp20 and all related to it,i may ask a little help from this nice community digging in same hole...
Well i have several sp20 miners,some moded with different fans to reduce noise and cool better,they run at about 1350ghs prox each,i do manual volt settings accordingly to temperature as fans are not auto they run on full speed,they served me well couple of months now,but today after i restarted one of them after tweaking voltage,yellow and green lights didnt light up at all,so after alot of differenet tries to recover it with switching power cords,restarting,sd card rebooting,and so on,i concluded that my controller board on top of the miner has probably gone.So i replaced this board with other from different miner,lights are up and miner starts normally,so my question is can this controller be repaired or i shouldnt bother(seems that controller board is getting power as some small leds on the board are up when board examined closely),or i need to replace it,if i do then i would ask any of you if could have spare one so i can buy it,it would be a really great help,as this miner sits now without work ,and you all know how they like to work;)

Thx for any help you provide me...
