white dotted lines on top left hand corner of television when I play dvds

[admin_exported]

Hi

Whenever I play dvd's on my Panansonic Plasma (BZ85B) tv, I seem to get white dotted lines on the top left hand corner. I have looked on the tv remote control but can't seem to find a relevant button to rid of the lines.

Can someone please tell me how I can do this?

Much appreciated

George
