Hi,
I recently picked up a BurgerTime that had a power supply problem. I was able to switch with one I had left over from a Super PacMan. That's not really relevant to my problem, but I wanted to give all the background I have on it.
Now, as soon as I turn the machine on, there's a loud buzz coming from the speaker. I can hear the game sounds and music underneath. I ran through the sound tests and everything seems ok.
I unplugged the monitor and the light to rule out interference from those. I also checked and all ground wires seem to be secure.
I checked the voltages to the sound board, thinking maybe there were too many volts going to it, but the +-5v and 12v are all within a volt (5. something and 12. something).
Here's a video with the buzzing. You can hear the game sounds underneath.

Anyone seen anything like this before or have anything else to try?
