I have had a little trouble with my MvC2 machine lately. When it starts up the screen gets smaller (it doesn’t take up the entire width of the monitor and the adjustments knobs don’t correct it when its distorted like this), and during game play I get annoying horizontal lines that distort the picture. Those annoying lines make it unplayable because you can’t really see what’s going on with all the flickering lines.
Well I kinda figured out how to fix the annoying lines (not the best way), I unplugged the video cord from the Jamma(?) that goes to the monitor. When I unplug it and plug it back in the lines go away, but the picture is still smaller. Here is a picture of the plug so you know what I am talking about: Mvc2 Cable. My HUGE problem is that I unplugged the cord and plugged it back in (while the game was on) to fix the annoying lines, and there was a flicker then the game went dead. The plug itself looks like it was shocked because there is a little black that you can see.
Now I am really pissed. I don’t know if the Naomi board is fried, if the jamma is fried, or if I just need a new power supply. The game won’t power on at all so I am thinking it is the power supply. So I am really hoping that someone who knows a lot about arcade machines (preferably MvC2, the big cabinet style) can help me out in figuring what the problem is. I hope to god that the entire machine isn’t shot, but right now it is looking like that.
So if anyone can help me out PLEASE let me know!
