I've noticed something strange on our new panny PW6 (about 70hrs on it now). on any input with or without a signal the left side of the screen has a very thin band up the left side which is only noticeable on black. When there is any other colour this band is not noticable, but on blacks its like the brightness is slightly higher in this area. Its minor but i wondered if there was a logical explanation. Plasma's aren't affected by magnets in speakers are they?? So does anyone know what this might be?!?
