LCD monitor with RGB to VGA adapter & static image

[mike boss]

I have my jamma wired Bad Dudes cabinet set up with a 19" LCD.
I use one of the readily available (on eBay) RGA to VGA adapters.

I've used these before and I'm actually using one with my current Final Fight cabinet.

Anyway, I decided I was going to try and adjust the picture as the Bad Dudes didn't quite 100% fill the screen.
I cycled thru the menu many times, trying different resolutions, and trying to move/enlarge the picture.

At one point the picture was very out of wack. I could not seem to get it back to normal. I powered down and powered on and  the problem still exists.

When the board comes on I see the title screen, then when it goes to the start screen the image becomes static. I can coin-up and hear the game playing blind so I assume the board itself is fine. Just the adapter will now not display.

Anyone had this issue, can I do anything ?
I tired to unplug and plug back in all connections, even tired resetting the board.
Did my many clicks of the menu button screw up the board ?

EDIT - I can upload a short video when I get home.


Thanks all

Check your power suppling the board. as i recall, those boards have some pretty hefty requirements for power (5 volts at 2 amps (2000 mA) be sure you can supply at LEAST that much.

Have you tried one of the other inputs on the Gonbes board (assuming that is what you are using)?

I did.
It has two VGA outputs, I tried both.

Was the horizontal sync.
Glad it is now fixed.
