I have found horizontal fix circuit from nffgames forum and building layout circuit to get etching board.
I have given this circuit a new short name: HCF which stands Horisontal Centering Fix
If you are interested to test the circuit on your own here is the circuit for you:
I am adding later my circuit layout and Eagle chematics and libraries for NE558 chip to this thread.
I am modding my layout to fix into 2 way active scart divider and hoping to add switch that makes the divider go poweroff-normal-horizontalfix states. When switch is on horizontalfix -state I can then rotate the 10k potentiometer to get my image sifted to right. So i get power from scart divider, and comboshit signal from scart input. then I add the horizontal and normal modes via 3 state switch.
Here is photo of my current fitting testing with paper:
Here are current layout photos of my work:
More images later.
