Setting up a replacement 192 x 64 display

New 192 x 64 displays usually need changing to suit the Sega supply. Older ones have a trace to cut between the ribbon connector and the P3 power plug. Newer ones have a "W1 Supply Pin" jumper area: bridge the two vertical pads marked "4" on the left side. If this is not set, the display will not work.
