Akai 54in TV has a problem....

I have a 54in. Akai tv.  There is a problem with the color, the green is not lined up with the red and blue.  I am not sure if there is a fix for this problem, or if there may be a simple fix.  Any help with this issue would be greatly appreciated. I would like to be able to watch tv and it not look like 3-D. Thanks so much.
