Top PCB

There was a ribbon connector between the top size of the main PCB and the control PCB for the LCD. 
This was removed and pin 1,2, 12 & 13 wired to the directly to the connector on the control PCB

Hooked up to a JAMMA board



UPDATE



 


Some gameboards tested have suffered from a 'washed out' image caused by the RGB levels from the board being too high.

A simple fix is show in the diagram,  tie the RGB inputs to ground via 75ohm resistors, this will result in having to adjust the brightness control for some games. Results will vary but this seemed to provide a good compromise across different boardsets.
