I'm having a similar problem. and think it is due to overheating. you can when the amp panel is removed there is no way for air to escape. the amp panel is a large piece of plastic with a black sticker over it. from the inside you can see 2 oval shaped holes just above the amp unit. try cutting the sticker portion away. (careful to power down the unit first!)
