Just as the title says,i (and many other UK )would love to build a circuit to fix the RGBs horizontal left shift problem ,that plagues all my consoles .
Any schematics in english .

Haven't made this myself, but it's on Viletim's site which is enough for me.

IC1 a,b,c (and d) are a quad 555 timer packaged on one IC, NE558. It's sometime quite difficult to find it.
IC2 is a standard LM1881 (sync separator)

This circuit seems interesting to do the the trick, but I didn't tested it yet. Do not hesitate to try it and share your information.

Ah,i see more clearly now.It's the way he had drawn the seperate Vcc and gnd(Vss) for each IC ,this made the schematic look like there were extra un named  ICs .

@bigsanta, did you go ahead and try this? i'm also very interested in a solution to the hshift problem but sadly my electronic skills are nil.

I've got most of my components ,but the rest will be a week or two.But when it's done,i will put up some pictures or a video of what the results look like!
