Thought I'd ask for some advice on an MV1-FS board I picked up recently.
All seemed well on first power-on, but after a little while it starts farting and spluttering at me, despite audio in the games still working
perfectly fine.
So I stripped it back - no cart or edge connector to worry about, and it happens on the bare motherboard with no cart connector / daughterboard
attached.
Is this what happens when a capacitor re-cap fix is needed?
Or am I looking at a deeper issue with the grounding or power on this board?
Other MVS boards run totally fine on this cab, so I know there's nothing wrong with power, grounding or audio in the cab or loom connectors.
Swapped out the cart connector daughterboard and bios from a working MV1-FS and the same thing happens, so I'm certain it's to do with something on this particular mobo.
Video of the offending MVS turned Geiger counter!
