SOURCE: no picture just comes sound
sounds like the Backlight has failed, if you look closely at the screen you should be able to see the image changing, but as there is no back light there is no luminescense so it will appear black or grey, It is probably the backlight inverter or element that has failed, if this is within warrany organise with them to fix it for free,

I had the same problem. I could get an analog audio signal but no digitial signal. My problem was with the cable box setting. I have Cox Cable. With the Cable remote I went to settings/settings/Audio out and selected HDMI. Worked like a charm
