Shinobi; Black Screen on New Astro City

[segasonic91]

I received a beautiful condition Shinobi board today and was very disappointed to find nothing but a black screen when I tried it on my NAC.

The seller kindly looked up information and found out that Shinobi does work correctly on Astro/Blast City cabs due to a missing ground pin. Would this also cause it to show a dead screen with no sound? There is power to the board as it lights up when I switch the cab on but I get nothing happening at all. The seller confirmed it was 100% working on his SuperGun when I purchased it.

If somebody could show me a picture of how the JAMMA converter needs to be jumped, it would be much apreciated. I will try doing to ground jump to see if it makes a difference. The board is 100% original (apart from the new 68000 and sound ROM) and in immaculate condition.

THANKS!

Shinobi needs a Sega connector to jamma right ? Do you have that connector between the board and the jamma connector for your cab?

[segasonic91]

Yep, I have a JAMMA adaptor on the PCB.

Have you checked the 5 volt ?
On one of my sega board i have to adjust the 5volt to 5.2 volt to get it to work.

[segasonic91]

Haven't checked the volts as yet. I will try that, thanks!

Meh, turned out to be my JAMMA connection. It is dodgy, like everything else about this bloody NAC cab I bought. Such a rip off.

Is the JAMMA Edge crimp or solder type?

[segasonic91]

Hmmm, I will have to check. It is the original JAMMA harness, the connection on the connection board seemed to be dodgy. Once I touched it, the picture worked. It was jumping around like crazy with Shinobi at first, but after playing with the JAMMA side for a bit, it settled down and was perfectly stable.
