I just cap kit'd this kortek [the closest kit I could find to match] my monitor was this one.Also replaced the b voltage big cap. All colors look good,but can not get the 'police trainer' picture to fill screen,the bottom, insert 1 coin white letters will not expand to fill screen,tried v lin. pot and does very little to help.also only 1 or 2 caps did not replace,so not sure what to do?
Thanks in short the bottom almost 1 /3 of screen is not being shown,but all logic is readable but crunched bottom row?

anyone have a download on at least the schematics of this kortek? Thanks
