Checked all fuses and connectors. none of the 555's do anything on the 2 boards but the 906's do. Also I have no power going to the 3 44's behind the Digital Stereo in the speaker panel. Has a new Rottendog MPU. Almost like something isn't plugged in? Had to pull the head to get it in the room. So in the head on the left side there are 3 sets of double connectors plugged together and in the cabinet bottom 2 connectors. One for the chime and the other goes up into the head. So 5 total sets? Any ideas on what to check? Thanks!
