Just a quick message to update anyone who might be interested.  I got my G7000 up and running by means of an RGB mod.  I can't say for certain but my assumption is that the PAL encoder was the faulty party since it just wasn't producing any output although all input signals looked good. 

I've put out a couple of youtube videos on my work with this machine.  If anyone is interested you can check them out below.

Part 1 - https://youtu.be/vdBXdHwgg-Q
Part 2 - https://youtu.be/AmRsu1x6fxc

Going forward I'd like to get a few more games and maybe revisit the RGB mod and try to build a smaller board.

If you're doing the RGB mod keep in mind that the schematic I used doesn't take account of the 5v required to force the TV in RGB mode over scart (5v to pin 16 of scart connector with 100ohm resistor in line).  I initially forgot about this so my 6 pin connector on the machine ended up as 1 pin short.  I got it working by taking the grounding through the chassis of the connector I used and while it works fine its not ideal.  What you want really is a 7 pin connector.

I use a 8 pin connector like the G7400.
