My tv is acting badly

My television color won't stop "bouncing" back and forth...it was working fine last night. Does this mean I may need to replace it??
 
The color is "bouncing" all over the place however it doesn't happen while I'm watching a DVD program or any of the HBO channels...I don't think it's my tv anymore.
 
I had this happen to my upstairs TV as well.... It turned out to be my cable box - the component out was borked... I flipped to HDMI and all was good.
