Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.
Have you try to replace your HDMI cable?I recommend you to pick up a good Monster HD700 HDMI cable from a local retail store like best buy or circuit city.In case it isn't the cable problem,you could return it. However,when you are a using the HDMI cable,it is normally either have both picture and sound or nothing at all.Are you sure you didn't hook up the audio OUTPUT from your TV back to a receiver input? Or even an optical output from the TV to the receiver? solutiondoct
