Title: Sega Naomi Cab monitor issue
Post by: gratzme on June 03, 2010, 03:17:18 pm

Hi, I have a sega naomi universal cab, with a sanwa 29E31S 31k monitor in it. The problem i have is that the picture is too wide for the screen. The picture is about an inch too wide each side. The monitor has a seperate control PCB which has some adjustments on it. However adjusting the horizontal pot does nothing except pinch the picture so the vertical lines bow inwards. I do have a schematic for the monitor but not sure where to start looking to fix the problem.

Any help would be great, thanks
