My Panasonic just stopped Functioning. I used to be viewing a display and the Tv set went blank. How do you switch off shut captioning? I are unable to get my receiver to Enjoy audio for my TV. I switched to AUX so that you can Engage in my iPod, http://zenithtvrepair80505.post-blogs.com/6948225/rumored-buzz-on-jvc-tv-screen-repair
