Television and Home Theater

our tv, which is only 3 years old, has fuzzy vertical lines in it. we can still see the picture but we have to deal with the lines to see it. whats going on???

I have 27" RCA tv. I was tossing a small plastic ball around playing with the cat, and the ball bounced off the top of the TV. Soon as it hit the tv, it went out. Now, when it is plugged in, it makes a high pitched beeping sound inside the tv. It is not operative at all now. The ball that hit the top is practically weightless, doesn't seem like it could do all that much damage. Any ideas?
