Sony KP-48v80

I have a 43" rear projection tv. (Older sony ) It has lines in the picture. Not the red, green or blue, but like static lines horizontal. And when there is a really white picture, like the progresive car insurance channel. It flickers and makes a tapping sound and wont quit till the commercial is over, ( or what ever is on. ) And What is An ( IC ) ? And can someone please tell me if the big red wires going to the tubes shock you if it is unplugged? Thank you.
