Thanks for the file, everything you ever wanted to know about VGA-scart RGB by the looks of it.
5.2 Schematic no.2 is how I connected my 2nd cable (cut female end off vga and soldered scart connector), the scart connector had pin numbers on both sides and is correctly soldered but even though each pin has continuity I now realise that vga pins 5, 6, 7, 8, 10, 11, 12 and 15 are connected somewhere in the cable or inside the male side of glued vga connector, is this something to do with the foil surrounding each ground cable perhaps?
5.5 Diagram 6 is how I connected my 1st cable together (male vga connector, male scart connector, 2 x 1k Ohm res, 1x 100 Ohm res, cable), Again both the vga and scart connectors had pin numbers on both sides and is also soldered correctly, has continuity and I've put sync cables back onto pin 20 from 19. Still no picture on tv though.
The voltage on the red 5v cable with 100 Ohm resistor reads at 2.8v and the yellow 12v cable reads at 12.2v. Bit stumped as to why this cable wouldn't work.
To rule out the video card being the problem I've got a cheap one coming from ebay that is in the supported section on the soft-15khz website, I'll grab another scart tv as well.
