I have a Galaxian PCB that won't show anything whatsoever on the screen. Pin 26 on z80 is toggling so I jumpered the pads to disable the watchdog. I have good clock signal. I also swapped out the z80 and put in the Galaxian test rom. Only get a steady tone out of the speaker (which I think is normal with the test rom but can't remember) and still nothing on the screen. Not sure where to go with this one?
