Cave pcb need 5+ adjustment? or?

[joeks]

I got a Mushihimesama board today,
but when i powerup the pcb, a led on the pcb (D6) flickers and i get a black screen with only 1 or 2 random moving lines on screen
Any idea? Could it be that i have to adjust my +5v setting on the power supply? or am i missing something?

My other Cave pcb's (Espgaluda en Esprade) work perfectly on this Sega Astro City cabinet.
I do have the original small psu in the cab by the way.

Thanks in advance!

There's someone getting the same problem here :

The different Astro City PSU :

He had to change his PSU for a more powerfull one ( NVS 4000 ) for the Cave System 3 , everything else ( CPS2 etc .. ) was working great.

It seems that " some " Astro PSU are not powerfull enough

Thank you very much! At least now i know the board board isn't broke.
Have to find me a stronger psu then.
Thanks!

It's not sure that you HAVE to change your PSU , but it may be a lead

Hi,

I recently had the same problem with a 7AN max Sega PSU (NAC).
Do no hesitate to test your PCB with ATX PSU !

Great Setsuan!
So i can hook up a normal computer ATX power supply to power up the pcb?
Any schematics for that sowewhere? Altough you picture is very clear.
Don't want to ruin my new Muchihimesama pcb

Thanks!

Hi Setsuan, it works!
Thanks again for making this guide. I just tested my new Mushihimesama pcb and it works like a charm
Only no sound at the moment because the ATX-hack only used the +5V, +12V and GND for now. But that's no big deal, at least i could test my new pcb.

You can have sound with this hack. You just have to plug it directly to your amp (from the jamma). I had the same problem before and it woks now ^^
