Xbox Live/TV question?

Question

Recently when I've been playing halo, I'd hear like a loud static noise and the picture would vanish only leaving a black screen, the controller would keep working, i could feel it vibrate, then in like 15 seconds, the sound will comeback then the picture.

Why is this happening, is it the TV or Live or something else

it's my 4-5th day on live if it helps.

Answer 1

try fixing the cables if not it probably your tv then

Answer 2

It really just sounds like your A/v Cables come loose and thats why the piture would vanish.
