I haven't tried to fix mine yet but I only got it a week ago. Before I start buying parts I think I'll watch this thread for a bit.

Whatever you figure out count me in.

Quoted from ChadH:

Just wanted to follow up with what I ended up doing to fix my Data East Star Wars sound. Last I posted, I said I was going to replace the caps on my power supply board. I pulled the power supply off and took one look at it and realized that it was not worth putting new caps on it. The board had been serviced (badly) over the years and had really bad solder jobs done on it. The circuit board was also bubbling and lifting really badly. It would have been a waste to replace caps on such a chewed up board.
So instead, I ordered a new Rottendog power supply.
I after I put the Rottendog in, the constant background hum (60 Hz?) was reduced quite a bit. But the buzzing coming from the dancing matrix lights and the DMD in attract mode was still there. In fact, this part sounded louder relative to the now reduced background hum.
So I unscrewed the sound board again and let it float free. This time it worked! It reduced the attract mode buzzing noises by about 90%! So I got some nylon screws (8-32) and nylon washers from Home Depot and used those to screw the sound board back in.
As far as I am concerned, my sound problems are resolved. Is it completely quiet now? No. But is it WAY better? Yes!

Mine already had a Rottendog when I got it. Like you not much background noise but in attract it was loud. Figured what the hell, it will only take a minute to try and it worked! Game is almost silent now, can't believe it. Bring home some nylon screws tomorrow and I'll consider mine fixed. Thank you.

So are you saying that the Rottendog PS is going to kill my game? That is what it had when I bought it and have never had a problem except for the hum which is now gone. I don't like the idea of having a time-bomb in my machine though so should I be worried?
