-   I'm having a similar problem. I wasted lemonade on the cords. Nothing else is malfunctioning, except for the monitor. It won't come on. the green light comes on for about 3 seconds, then turns orange. Please can someone tell me if I need another monitor or if this problem can be fixed . Thanks!!! -   dacole2004
