Look at it on the QVC channel where you have boxes with straight lines. If any of the 3 colors are bowed and 1 inch off, then it needs parts inside. If the colors are straight and only 1/4 inch off, you can adjust it. Using the remote, in the menus find convergence to adjust. Your user manual will explain it. At WWW.Toshiba.com you can download the manual if you do not have it.

That is a mirrior adjustment problem, it is pretty complex to fix yourself and you can really mess up the T.V. if you don't know what you are doing. I suggest a T.V. repair man that specializes in DLP TV's.
