DIF-S2 mk 1 - DJ Tools mixer- did I break it???

Been getting a lot of bleeding and dead space from the mini innofader the mixer came with. So I followed this guide too try and fix it: Redirect Notice

But now it seems like my mixer isn’t receiving any audio input?? When I turn it off and on, a single green diode, at the bottom of the left EQ, flashes several times and then stops.

Did I mess something up during the cf calibrator? Touch some metal I shouldn’t have?
