As Dave pointed out, you have given us very little information on which to guess what your problem might be.
I’m guessing that you’re looking at your computer screen and seeing delightful video (that you may have color-corrected until it looked great) and when you view it on a regular old TV it looks like crap. That’s because computer screens and TVs are very different when it comes to how they represent light and color. A white that’s RGB values are 255 255 255 (pure white in AE) is beyond the acceptable color limit for broadcast television. (Also a black that’s 0 0 0 is too black for broadcast TV.)
My suggestion; color correct on a broadcast monitor.
Or, if you don’t have the thousands of dollars that it takes to get such equipment, at the very least put an adjustment layer on top of everything that brings it back into legal broadcast color range. (A levels effect with the output black set to 16 and the output white set to 235 will help.)
There is a ton you could (and should) learn about color space and broadcast legal color issues. Google for them.
Of course, this is just a guess and might have nothing to do with your particular issue.
