Hey everyone,
well after only two months of use my supergun seems to have gone belly up. I have three different PCBs , a MVS one slot, a capcom A/B board set, and another random game.

With any of the above I get no juice to the respective boards....except on a one in 50 try. When juice does get to the board I get nothing on screen.

I've cracked the MAS systems supernova open and all the connections seem to be intact. I did notice a adjustable setting on the power supply marked 5v. I haven't touched this, but before I replace the whole power supply I'm wondering what that dial does?

In any event help would be great on this one.

before you do anything, I'd contact MAS. They still might be able to do something for you, or worst case they'll tell you what that dial is for.

The little knob on the power supply is use to adjust the voltage of +5V, using a multimeter, turn the knob around till you get +5V

If its not working, your PSU (power supply) is dead. I have heard when swicthing games with a neo, be it 2,4,6 slot board, it can kill your PSU unless its a mvs exact one. For switching games I reccomend useing a proprietary PSU.

Dont mess with things trying to get it to work, no power = dead PSU.

I would contact danny of gamescity and get one from him, he is not the most talkative guy but he sells ones for 40$.

Gamescity- 1-626-573-3832

And good luck with it, I dont reccomend super guns/nova's personally because the S-vid has line crawl, and the composite is a nightmare, remember these are fitted to RGB clarity, which is the best of the three noted.

Unfortunatly I bought the system second hand so I'm not sure on the contacting MAS...yet....

I'll try a multimeter and a knob action. where should I be checking for 5v+? off the harness or off the power supply?

either side is fine.

the PSU doesn't matter, I've been using arcade PSUs as well as PC AT power supplies with no probs at all with both the MVS and other jamma boards. if it's dead, you can replace it for either type (although they prolly used an original arcade supply for space reasons in the supergun)

if it just stopped working, and everything is in tact, it could be a burned out power supply, bad fuse.

But mas has like a 90 day warrenty i think, so contact them.
