OK, this is a really bizarre question. My Neo-Geo arcade has been
acting up, and a couple weekends ago when I tried to take a look at
it, I couldn't even get a picture. Today I got the bits to take out
the security screws so I could get into the part where the
powersupply is.
It was just up for 4 1/2 hours without any problems. The only things
that have been done is to wipe the grill where the fan is off (it was
really filthy), and to move an old sewing machine that was sitting on
the floor next to it (unplugged). The sewing machine was sitting
next to where the transformer is in the cabinet. Is there any way
having it sitting there could have been effecting the power?
It's a really stupid and bizarre question, and I don't see how it
could effect it, but I can't figure out why the system seems to be
working now. Of course a more logical explanation is that there is
something loose inside.

Something loose/cold solder joints would be something to look at. When you
open the case you naturally move things around a little which can make
connections make/break.
Equipment of any type that is off should have no affect (unless it has
powerful magnets placed near a monitor).

I don't see how. It's possible for the stray field of one transformer to
couple to another (valve audio amplifers nearly always had the cores of
the mains and output transformer at right angles to reduce hum, for
example), but I've never heard of stray fields or metal affecting a mains
transformer.

I didn't see how this could be it either, but wanted to double check
and make sure I'd not forgotten something. It's been a *LONG* time
since I studied transformer theory, and I've never claimed I was a
good electrician :^)
