Won a dsp built kit for k2. It was bought knowin it was bad. Double check part values orientation. Everything checks out in menus. I can make adjustments set clock but there's no sound unless u put dsp in bypass then I can hear a signal again. I did voltage checks in manual and found that on u1-5 i get 5v where it calls for 0. U1-14 I get 0 where it calls for 5v. According to schematic this is the muting circuit. I'm thinkin that I need a new firmware chip at u1? The seller thought it was the dspx board. But since I'm not gettin the right voltage without dspx board installed I ruled it out. Is there a menu setting that would trigger the muting?
