I have a model that supports RGB through SCART and all I apparently need is to install the socket and add the missing components. However, there's no option in the service menu to enable a SCART/RGB channel. Would a voltage on the blanking pin (Pins 16 and 8 maybe?) be enough to display a RGB image? Here's a picture of the schematic:

I am busy planning to mod a LG CRT TV, getting a feed from arcade pcb analog rgb video.
I have bumped into this great resource about arcade analog rgb mapping to scart explaining which resistors sizes to use for each line!!! to lower the voltage to scart levels as Mark suggested here.
Great resource, I am just looking at jamma2euro scart section but lots of info here.

Another vga/rgb to scart using schematics, too difficult for me but for those that are experts this could be a great find:

Since CRT Emudriver started outputting csync the need for the combination of H and V sync in the "VGA" to scart cables is no longer necessary. Just a resistor on csync.
