Try setting a portable fan aimed toward the cooling vents on the back of the set. If this eliminates or reduces the occurance of the lines, this means a circuit that controls the off/on of individual pixels has developed a thermal problem. This circuit is ordinarily loacted on the main circuit board and is likely to degrade further. You might inquire at the Panasonic service center if they have an exchange program in place and they will probably be able to confirm my suspicions.

this sounds like a bad capacitor. If you want to fix it yourself and know how to solder on a pcb, then replace all of the electrolytic capacitors.
