If it doesn't go to cross-hatch, it means the mobo isn't powering on at all, roms are completely shot, or the video signal isn't getting from the mobo to the monitor.

Do you have a multimeter? If so, check the JAMMA harness and see if the mobo is getting its +5V and +12V.

Can you hear sound coming from the speakers?

JAMMA edge not connected all the way?

Fuses/power Supply.

from examining what works (monitor, flourescent- both ac powered) and what doesn't (mobo - dc powered) I'd say power supply as well. Do the lights in the coin door turn on? (those are dc powered as well.)

sliceypete · Oct 14, 2005

the jamma thing doesnt want to go in all the way i try pushing it in. ill check if the coin thing get any power. no i cant hear anything coming from the speakers at all.
ill update u guys in a few min just going to see if the coin thing light up i dont thing it does

sliceypete · Oct 14, 2005

ok just checked the coin door does not turn no at all.ok so it a problem wit the power supply. is this easliy fix or do i need to get a new power supply and if so where would i get one.(im not 2 good with arcades so dont flame me lol)

i hope u guys can help me out pce i got school :mad:

I'f I'm not mistaken, I'd say that the power setup in there is a bob roberts setup... to make it REALLY easy on yourself... just get another power supply off him. http://homearcade.org/BBBB/parts.html What you will want to get is the "Switching Power Supply". It goes for $25 plus shipping. One quick thing though... when you have power running, there should be a little red indicator light on the power supply itself. If it is not on, then it is surelly your power supply or wiring TO the power supply.

You might want to check the fuses before placing that order, and using a multimeter to check the voltage would be a good idea. If you don't have a multimeter, nows the time to buy one.

if the fuse was blown, he'd have no negative ac voltage

thanks for all the help guys. i should be geting the new power supply by the end of the week and hopefully ill have my cab fully working :glee:

sliceypete · Oct 16, 2005

hmm i was thinking and i have a question to ask. is there any other way i can power on the mvs board. i just want to see if it works 2.

Vectorman0 · Oct 16, 2005

If you had a spare computer power supply around, you could probably hack that up to do some testing.

sliceypete · Oct 16, 2005

yea i do( i have a extra 400 wat power supply). do u have a tutorial on how 2 do this?

stuffmonger · Oct 17, 2005

I wouldn't reccomend modifying a power supply to someone new electronics. For one, you'll have to solder one of the wires to a contact on the pcb in the power supply to let you turn the power supply on without a computer (unless it's an AT psu instead of ATX). When I modded my first computer psu, I think I shocked myself like 4 or 5 times :loco:

while trying to find a good contact for the start wire.

I was thinking he could just use a small piece of wire to jump it on the outside. I can't remember the exact wires though. I think it was PS On to PG, or ground; something along those lines. Google would help find more info.

I guess I just like everything to be contained in one neat little box... meh.

To do that, I think the easiest way would be to get a scart cable and modify it if you can... otherwise, you'd have to find something that would convert a high res 31khz to low res 15khz.

you do realize that that's well over $100... though, I guess it'd work. with the jpak, you shouldn't need to hack any controllers, as it already does for you.
