I think I'm having a similar problem its just that the monday night football song isn't playing. I have heard it a couple of times when i bought the machine but not reciently. That is the only sound problem. All other sounds seems to be working.Is there a sound rom just for the song? And how long does the machine have to be standing idle before the song starts playing? I turn it off when I don't use it but I let it sit for a while and haven't heard the song. I haven't dug deep into it yet. Does anybody have any ideas where to start?
