I have an Alpine ski that plays but only displays blue. Im new to pcb repair and taito schematics are still over my head so... Is there a section of the pcb that controls output display colors?
 
Trace the pins from the edge connector back up the board and you'll find the devices that output the video. Taito has a habit of using custom hybrids on the outputs.

Are you sure it's not a monitor issue?
 
Thanks for the reply, Yes the monitor display is ok, Its actually my jungle hunt cab that im using for testing. Hmmm potential custom chip replacement needed probably not good :(.
 
I have a boneyard with lots of parts boards. Just let me know what custom chip you need.
