Why is my tv flashing colors?

I have a Sylvania its a little over 4 years old, but its never acted up in the past. I was watching T.V earlier until the screen went to "DVD" and I couldn't change the channel. After hitting the channel buttons a few times it finally went back to normal and I could change it. Then later, the screen started flashing red, green, white, black, and maybe yellow i dont remember. Now its just stuck on the DVD video screen and no buttons will work. Does anyone know how to fix this? Thanks.
