Title: Tron video connections to composite sync
Post by: ToplessZ on September 22, 2008, 05:49:34 pm
I have a Tron machine that had a K4900 in it.  However I needed to sell another machine that needed a 19" monitor so I took it out and put it in the other game since at the time the Tron wasnt working.  I got the Tron working now and I have another 19" tube and a capatible Wei Ya chassis that I want to use in the Tron now.  So heres the questions:  How do you sync a Tron PCB to composite sync?

why don't you just connect it up and see what happens-can't cause any damage

I have, there's three wires that do the sync. I've connected to each and all together and in pairs.

i don't think there should be 3 wires,maybe 2 one for the horizontal and one for the vertical syncs
who many wires do have altogether to the video input plug

Its got the typical R,G,B,Ground on one plug, then its got another 3 slot plug that has two wires going into the first slot, and one wire going into the other two.
Ive read about using a 7408? but Im not sure how to wire it and where to get one

the schem shows the red/green/blue/ground on one plug and ground/vsync/hsync on the other
see if the 2 ground read continuity
your wei ya chassis has just a comp sync connection i take it
