Non-functioning Soundcraft UI24r mixer/interface. It was working fine, still turns on, but doesn’t fully boot up. It may be the known issue with F1 resistor (you can Google that); I tried to solder across it without resolution.
As I stated: it was working perfectly fine, all channels/preamps, software functions, etc. You can get a whole new CPU board for around $300. This is sold as is, no guarantees. Buy it either for parts, or to try replacing the CPU board to get an amazing mixer for cheap.
