Sega doesn't even explicitly state what the monitors are. I had to do a fair amount of research to figure out what was in this Turbo cabaret, a Matsushita TM-144G. and the vertical collapse issue it had was because signal wasn't applied to it. we're in bizarroland.

Glad you figured it out. Bizarroland for sure!

in Sega-ese, white is ground and blue is sync, and those plugs in the picture are what they should be coming off the game harness. I can't really make out what's going to the monitor but it looks like too many wires.

pin 1: red
pin 2: green
pin 3: blue
pin 4: video ground (white wire)
pin 10: composite sync (blue wire)

it looks like they had the composite sync run to both horizontal and vertical sync pins, you'll need to ditch that one on vertical sync pin 9. also I don't know why people put the video grounds on the 3 pin header side, what's wrong with putting it on pin 4? if you had ground on the 6 pin plug you would have the flexibility to move the 3 pin plug over a position so it's only on pin 10.

I am not sure if I should post this here but here goes. I have a Matsushita 14" in a Sega Turbo. If I connect my TPG to the monitor I get a good pattern and color. With the monitor hooked to the game I get nothing. If I hook the game to a different monitor, I get a good picture. So the game works, the monitor works, just not together.

if you're running the original power supply I would say that's where your fault lies. you've done everything imaginable with the monitor and the TPG worked with it.

My hunch would also be power supply/cabinet harness issue. Since w/ TPG the signal is generated off battery, but any other board you try is being powered by the power supply & harness. That seems to be the only different variable at play between TPG & the other game boards you've tried.

What I don't understand is why it shows a image when the game board is connected to a different monitor all while still in the factory cabinet. It will run on its own power when when hooked to the other monitor and the monitor runs on its factory power with the TPG. I'll look into it but it doesn't add up to me but you guys have the experience that I lack. Much appreciated.

Sorry I was replying to the original poster, not to your post specifically.

In your case hard to say, especially if you are hooking the game board up to both monitors in the same way in terms of sync connection.

we got new ones that run on AC power. the new standard res patterns are awesome.
