This is common with plasmas actually. So long as the image fades and isn't a constant residual affect I wouldn't worry about it, but if it is constant and doesn't fade, its a sign of plasma burn out. The plasma in the tv has been active too long with one specific image or series of images. 

Plasma televisions have been complained about because of this.

2. To lighten the screen, press and release 2nd key, and then press and hold Down-arrow key until the display is sufficiently light.
