Do you get any sound at all through it when in the ‘mic’ condition? Are there any bad hums or crackles?

It’s unlikely to be a chip fault, more likely to be a capacitor fault…. the input has a pair of high voltage capacitors separating away the phantom power from the input chip. If one of those goes ‘soft’, then it can cause the input to stop working, but the line in would work OK. But that’s speculation….

If you want me to fix it, just send it to me at the Sound House.
