I'm trying to hook a Drews Deuces Wild PCB to a LCD monitor with a CGA to VGA converter board. The video plug didn't seem to have a video sync, and the jamma isn't standard. The video corde only had RGB and black. Does anyone have a jamma diagram for something like this? The RGB were on pin 1, 2 and 3 on the parts side of the PCB. Here are some pictures of what I have too. Thanks for any help.
-
Are you sure the RGB is pins 1, 2, & 3 or is it pins 34, 35, & 36 ? I might be able to help.

It may be 34, 35 and 36, depending on how you number the wires. It's on the parts side of the jamma plug, on the far left side. It's red, green and blue from left to right.

Ok, the video ground (black) should be solder side pin 36, opposite side of the red video wire. You also have a composite sync, which is pin 27 on parts side. Depending on the converter you are using, you could use that but me personally I use the vertical sync, pin 5 and horizontal sync, pin 6 both on the solder side. You can't use all 3 syncs at the same time. It's either composite or H and V. You could let me know what kind of CGA to VGA converter you are using or just try and see what works for you.

I tried the wires from pin 5 and 6 solder side, as I thought they were the video sync wires, and it didn't work. I tried them both ways since I wasn't sure which was vertical and which was horizontal on the converter board. The converter board I am using is "BLEE Arcade Game RGB CGA EGA YUV to VGA HD Video Converter Board 1 VGA Single Output for CRT LCD PDP". I'm including a picture of the card and how I wired it up to the yellow and grey wires. There is no wire on slot 27 on parts side of the jamma harness. Thanks for all your help.

Connect the grey wire to pin 27 on parts side. Do not connect yellow wire to anything. Remember to press the "auto" button on the converter the first time you power up. The red light will flash then steady when it finds the right frequency.
-
Also those 3 blue and white knobs are your color (Rgb), they seem to be turned way down or way up. If they are turned way down you might not see a video image.
-
They do look "way down", turn one at a time to see if that color comes up.

It worked. Thanks a lot for your help. Now the screen is jumping around when you try to play it. Here's a video of what it's doing.

Try pressing the "auto" button on the converter and see if that fixes it. Those converters aren't 100% compatible with those poker boards. You need one like this :

I got one of these boards. I'm not having any luck yet with it. Any idea what the dip switches might need to be set at? I'm either getting out of range, or just no signal on the settings I've tried. Thanks for you help.

The Wei-ya is a 12VDC converter vs 5VDC for the Jamma. You can try these two settings and see which one works best for you, you will have to reset your lcd monitor to factory default settings then make the necessary adjustments after.
(a) Join solder side pins 5 & 6 on edge connector and connect converter grey wire. Turn on dip switch 3 only.
(b) Connect converter white wire to solder side pin 5 on edge connector and connect converter grey wire to solder side pin 6 on edge connector (pins are not joined). Turn on dip switches 1, 2 & 4.
Let me know how it goes.

How would I reset the monitor to factory settings, if I can't find any such option in the OSD menu? I have a few different monitors that I could try, but they are all older and I don't see any factory reset on any of them. Thanks again.

The factory reset would make things a little easier to set up but you don't have to do it.

I tried both method a and b with no success. I found a monitor that does have factory reset (allthough you have to have it working to access the menu, then I assume it takes on the settings of what it's plugged in to), and tried that monitor as well after resetting. I got no signal on that one, and "Out of Range H:35khz V:3938Hz Max:1280 x 1024" on the first monitor I sort of had working with the cheapy converter card.
