Crazy Transformer question

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. Zane -- -- | Zane H.
