Sega-Naomi

I have a naomi 1 that I just bought, it was working fine at the arcade running marvel vs capcom 2. When I turn it on I hear no sound, and all the screen shows is a purple line and some other horizontal white lines on the screen. What should I do? Also what do I need to take pictures of?

try adjusting the horizontal hold and reference your monitor against the frequency of the mobo video output

I found that the capcom input wire had come lose. It works now.

I've got a new problem to show:







and







As you can (or maybe can't see) its stretched vertically, and I can't fix it with the stretch vertically knob on the control switch panel (its a little square on a wire attached to the moniter) as its stretched only at the top and bottom not smoothly stretched all the way up and down.

take a photo of the grid test pattern so we can see more clearly if it is linearity related

here you go. What do I do to fix that?

and it was not like this before?

what monitor is it,a sanwa 29es31s or a nanao ms2932?

I got it used from an arcade, not too sure if it was stretched like that before. Where do I check the moniter brand?

Vertical linearity problem. Unless you have a vertical linearity adjustment (Common on TVs, but VERY uncommon on arcade monitors) you'll probably need to put a cap kit in it.
