Help, black screen and no sound after consolization MV2F .

[xmen06]

Hello all,
I have tried to consolize a MVS NEOGEO.
It's a 2 slots MV2F.
I have made a mistake in the alimention and invert the cable with negative and positive.
I have corrected the alimentation and the led on the motherboard is on but i have no signal on screen .
I have plug headphone on the jack from the slot and i have no sound.
Does i have broken my slot or there is someting to do.

Thanks

Probably in pause mode.
Make sure dip switch 8 is set to the off position.

And i put the 7 up for freeplay.
I have put a game on it and still no screen and no sound.
I think maybe a chispet is dead on it.

Big Bear is telling you, you probably activated everything except freeplay.

Whats the 5V rail actually delivering?
If it there is a short, voltage should collapse, the IC would heat.
The YM2610 always gets warm, you can ignore that.

A quick google makes it seem like it may be somewhat of a known issue with GBS-Control. It may not be the best upscaler for Neo Geo. I'm not sure if the video board will help with this issue.
