If you have checked the connection and all the cables are connected to the appropriate matching colors, then try connecting the component video cables to another set of component video jacks on the television - if available. Afterwards, be sure to tune the TV to the newly-connected video input to see the picture from the connected device. However, if your TV does not have a another set of component video jacks or if the issue is not resolved, try replacing the component video cables.
