I just converted my XRGB2 to SCART by changing the jumpers from N to P as mentioned on this forum.  After doing this I found I had no sync.  

After tracing the connections I found that after changing the jumpers the XRGB2 expected sync to be on pin 16, not pin 20 where it should be (at least on every SCART TV/monitor I have used).

I removed the jumpers from pin 16 and 20, then soldered a wire from pin 20 to the rear jumper pad for pin 16 and all was working properly.  

I don't recommend jumpering pin 16 directly to pin 20 as some SCART cables have a switching voltage on pin 16.  

Thought this information may be useful to somebody.
