Penrose No Power

Completed the build and checked for shorts between +/-12v and ground. When attached i get no lights. Where should I start?

  • Other strange behavior. I still have no lights. If I patch just from the output To my mixer I get a continuous tone. No other function seem to work.

    I'm still lost and looking for some guidance. Anyone? I guess the tile of my post is wrong. I do have power just no lights. I noticed if i put a finger on the pins of the MCP4821 the constant tone goes away. When I release my finger it comes back. I seem to continuity between pin7 and GND of the power connector pin. I've also checked the 10K resistors as I saw you mention in another post about them affecting the lights.
