Finally fixed.
The problem is that the JC jumper (Red small wire with black connector) has two modes. N=Normal, W=Wide.
The jumper was in wide mode and for that the horizontal coil cannot reduce the screen so long.
When i put it in normal mode the screen reduced and made possible to adjust with the horizontal coil.
Now the monitor is perfect with correct colors, width and height
See image 1 in yellow circle
and finally the second image with monitor running a game (the image is not best because i am not good to take photos)
I have repaired a lot of pinball machines (
www.firepower.gr) but it was my first attempt to repair a cabin with monitor problem.
I want to thanks again Ken Layton for his help.
