Hey Guys. I just got my Attack from Mars and it's awesome! One issue though...
Out of the blue, THE loudest BRRRRRrrrrrrrrAAAAAAAAAA!!!! Noise happened briefly and stopped after 3 seconds. Scared the living crap out of me. I couldn't see any problem or shorts. I reseated every cable and let the machine just sit in the "ON" state. 2 hours later BRRRRRRrrrrrrrAAAAAAAAaa!!!! Same noise but this time, it didn't stop. I opened the back box and moved wires and pressed on all the cable connections. Nothing changed. I opened the playfield up and checked the speaker...no apparent problem visible. I reset the power to the machine and it booted up fine again. I let it sit again and about 45 minutes later, it did it again and wouldn't stop. I have no idea what is going on. I wish I had recorded the sound so I could explain it better but I didn't think about it until just now.
Also, the left speaker is very loud by comparison to the right speaker all the time. It sounds as though the left speaker is blown.
Does anyone have any ideas of what I might be able to check?
