Sony DSR-PD150 CCD Problems?

I recently lucked into getting a Sony DSR-PD150, however the problem right now is that in image coming off the CCD all white light is a light yellow color. I have already checked the display for color errors, by running the color bars test that the camera has internally. Is is possible to user fix this CCD issue? Also this camera is not covered by any warrantee as far as i know.
