As Kevin noted, those look like interference from Macrovision or a similar copy protection scheme. Here's one of my TVs displaying similar lines when I played a copy-protected DVD:
The lines disappeared completely when I played a non-copy protected DVD. To confirm that's what you have, play a non-copy protected DVD or hook up some other source (VHS player?) using non-copy protected material.
Retrace lines look different; they slant all the way from one side to the other. Here's one of my TVs with and without visible retrace lines (I'm using a little test CRT, not the TV's native picture tube):
Retrace lines generally disappear when you turn the brightness down beyond a certain point, while Macrovision lines are less affected.
