New developments, I noticed that I had no 28vdc led light on the power supply. I removed the connector and the 28vdv light came back on. So I figured something was dragging down my 28vdc. I unplugged the title rack keyboard interface p1 connector and now I have sound so something on the board is bad. I'm able to input songs with p1 removed but it will not let me flip the pages. I did some testing and found two questionable components. Q1 and q2 are the same component but test differently under diode setting so I suspect one is bad. Also found resistor way over spec .see pictures.
