Sega Astro City +5v Help

As the title says I need help with the +5v setting on a Sega Astro City. I've been told its the cause of some of my games acting up and I was trying to figure out how you adjust this. Any help or information would be appreciated, especially a manual for an Astro City. Thanks!

I have an original Astro City but the new Astro City I think only has better speakers. Thanks a lot for this. I found where you adjust it. It seems to have a different power supply but without being a giraffe I can't get my head all the way in the cabinet to see how exactly you adjust the voltage. There's just a hole in the top of the power supply that says V ADJ and its in the same spot as the new Astro City manual. Anyone have any clue on how to get in there and change it? or how much a new power supply costs?

Put a screwdriver (can't remember if its a posidrive of flatblade) in the hole. Connect a multi-meter to the 5v on your loom and adjust until you're happy.

Its a bit of a fiddle

Ok, I'll have to have my dad help out. He's got the multi-meter and knows what he's doing. I may have finally figured out why some games "quit working right". I got a Legend of Air Cavalry the other day and it wouldn't work, well low and behold the guy who sold it to me let me know that was the error. Sure enough multiple adjustments and it worked fine.
