neo geo machine will not turn even after i put in a new power supply..
BobA:
Should be marked somewhere on the supply what size fuse to use. Sorry I got the idea you were using a PC supply from one of your other threads. 3 amp at 125 V sounds about the size for a 300W supply. I cannot check as I don't have one of those arcade supplys at the moment. Maybe someone else can guide you if you give them the make and model of the supply.

You seem to be going only be video, I would check for sound first to see if everything is hooked up right and you have a good motherboard to start with.
When the system first starts up there will be an intro jingle and then if the intro music is enabled for your game it will start playing. If you can hear any of that, then you know it is something wrong with the video cabling or the monitor.
Also, check that you are getting +5V from the power supply. It doesn't matter if you are using the new or the old PSU, but you may need to tweak it to to +5. There is usually a little metal knob on side of the PSU for this. You should still see some signs of life even with the voltage off, but worth checking.

My Big Red Neo machine had the power switch completely bypassed when I got it. It was just plug it in and go. Not sure if it's common for those switches to go bad on those machines or not.

Robot, try hooking up an ATX or AT power supply just to the MVS board and then power it up. If you're still having problems I could probably let you test the board/game with my cab. I live in Raleigh and I'll be back home after this Sunday. Let me know if you're still having problems.

First of all, is this a dedicated Neo Geo? If so, is it a 4 slot or a 6 slot? Or is this a conversion? If so is it a single slot or two slot?
This all makes a difference in this power supply used in the cabinet.
