I picked up a flat face Trinitron yesterday for peanuts. I plan to use
this as an arcade game monitor (in a MAME setup) and need RGB and
seperate sync inputs.

From the schem, I see the "jungle" chip has RGB outputs, so I assume I
can insert the color gun signals here. What signal level is it wanting
to see here? .7v? Also, I need to keep the OSD for setup and
adjustments, so will this be the best option?


The schem is on eserviceinfo and model is KV20FS10. Sorry, I'd hotlink it but apparently I can't until I get some posts under my belt.



I can see a good place to tap in H sync (after the seperator), but I
don't see any reference to V sync. I see the output IC, but its a PITA
to trace it back.


Suggestions?

Scratch the part about tracing the V output back. I see now it ties to what looks like a balanced drive signal from the jungle chip.
