For the vga connector, there might be resolution/overscan issues, not sure. Make sure you use an app that displays it in full screen, with nothing else showing - no scrollbars, no titlebars, no captions, nothing else, only the black and white boxes visible (I used irfanview, with the captions turned off).
My ADC targets:
AV: low 18, high 220, delta 1
Comp: 16, 235, 1
PC: 2, 235, 1
2nd: 1, 235, 1
Not sure if those maybe vary with firmware and batch (and even region, this is a UK set), but should get you vaguely close. From then on you can check with a colorimeter, maybe fiddle the ADC result to get it in the right ballpark.
