This is a follow up to my previous thread about my Electrocoin 6-slot Neo Geo in distress. My MV6 board now boots and works with 3/6 slots. The Hantarex US250 power supply power supply turned out to be a pain though.
The US 250 supply previously made a high pitched whining sound and didn't give power. After reflowing all solder joints the supply worked perfectly fine when disconnected from the game, but plugging in the MV6 board makes the beeping sound return, even though the game plays okay.
Yesterday I replaced all the supply capacitors except the big one with Nippon 105C low esr caps. The problem remains the same: a working arcade game but a screaming power supply.
I'm a bit stuck here. Can anyone give me some advice on how to proceed?
