JVC mini camcorder GR-D32U after replacement of sensor..bluish overtone?

I had the same problem & the repair costs were covered by JVC. However, the camcorder with the new CCD sensor does not give true colour as it did when I originally purchased it (bark on a tree was brown, grass was green). When either looking through the lens finder or the monitor the image has a grainy bluish overtone & there is a white glare (bark on tree is a glaring whitish, grass is blue). I returned it to the repair shop & they put in another one ... or so they said. But, the problem remains .. everything has a layering of light blue overtones & the white glare reflection remains (colours are not as seen by the naked eye). Has anyone experienced this after having the new sensor put in?
