I recently bought a TMNT cabinet and I've gotten everything working great. The only problem now is that every now and then a glitched graphic comes on the screen. It seems to only happen when I'm either attacking or being attacked, or during a cutscene when it's not a common sprite being used.

When the glitched sprite comes on the screen, the sound goes away and immediately starts to sound like the speaker is blown, but then if I stand still after I kill all the enemies and wait about 5 seconds, the sound is restored to normal.

At first I thought a wire was shorting out, because it was happening every time I was attacking something, but it also happens when I'm being attacked and not pressing any buttons, and happens on both the first and second player (I only have the 2 player version).

Do you guys have any ideas what the problem might be?

Thanks in advance.

Check your voltages and connections. If they are okay pop the board into test mode and see if it all checks out okay.
