On my just acquired Space Invaders upright occasionally on boot up the game will make very loud noise. It sounds like the game noises playing all at once. The screen is also garbled. It last only a few seconds and then stops and then finishes booting up normally. It doesn't happen all the time. Maybe 2 or 3 times out of 10. When I tried to add a Braze High score save kit, the loud boot up noise and garbled screen would not stop. After about 30 seconds I turned the game off. I tried that several times with the same results. I returned the kit thinking there's something wrong with it but now I'm not so sure. Any ideas? Thank you.
