Hi all,
Regarding my topic about my Defender cab here :
http://arcadecontrols.com/arcade.htmI have a problem with the monitor

I can adjust the horizontal screen position !

A good part of the picture is missing... the left part of the screen... and I can't adjust it !!!
I suppose I've to adjust it with this :

THere is three pins to use, but when I plug the red wire on each of them, I see no difference...

That red wire goes to 2 pins, than to this coil :

Do you thing that coil is broken ? How can I check it ?
Thanks for your help
