Quoted from Jakers:One of the crystal ball modes does this. I believe the mode is called "Lights On".
That only happens for specific moments during gameplay. OP sound like he has a problem with one of the LED boards in the game.
flamehead there is a guide in the WOZ manual that explains how to address lighting board issues. You should read that and then probably call JJP since it’s highly likely you will need to order some parts. If you are under warranty they won’t cost you anything.
