Most likely the BLUE LCD panel is failing, as the RED and GREEN LCD panels will create a Greenish picture....actually it's a LIME green color.
The part cost is $723.20 and the labor to install and align it will be around $300.00.
Very expensive, and you will need to find a Panasonic Authorized Service Center to replace this part, as the alignment is very critical on this.
