As some of you know Ive been rebuilding the dr who I just picked up. I finally got all the parts needed and it booted up!
The problem Im having is the switch matrix. No switches are working at all. Ive checked the driver board, good voltage at all of the tp points. Ive tested the switches, voltage going to them. I jumped the pins on the cpu board and nothing.. Maybe the U20-U14?
It also boots up then tells me check fuses 114 and 115. The fuses are good....?
Any ideas before I tear apart the cpu?
