how can i fix my sony trinitron model num kv-27522 32" television?

i have dropped my 32" sony television on the pavement and now when it powers up it displays a rainbow effect. also on the bottom of the screen the image is pulled in on each of the lower corners like a half an inch. help i really dont want to purchase another tv. this one worked perfect before this. the rainbow effect like originates in the center of the screen and moves out to the edges.
