G07 horizontal issue

[chiemgau1]

Hopefully someone can help out with this.
I have a G07 monitor I just put in with a 19 in 1 jamma (horizontal) pcb.
I can't get the picture to fill the screen on the sides.
If I mess with the horizontal frequency it will fill the screen up nice but the picture is out of sync.
I've tried to switch the sync off the board from neg to pos but the picture moved very far left.
The width coil can't cover the amount needed to fill the screen.
Any ideas.
Thanks

I have read the Bob Roberts page about the horizontal width but with some limited understanding of it.
Before trying to replace those caps I wanted to make sure that I had attempted everything else.
Also I'm not sure about testing the old one.
I do have a tester but have never used it for this before.

Thanks
