Don't worry I have also experienced this problem to. My cat Max has a habit of being sick every now and again and yes it's when he sits on the TV. He loves it there as it gets warm. Just the same way he loves to sit on the washing machine when it gets hot. Anyway, he was sick down the back of the tv and it wouldn't work again after that. We had to take it apart and clean it all out. Not a noce job really.
