Panny HD - Static lines

Panasonic 47WX49 HDTV
I cant really get a good picture with my camera, but will try and explain.
I can see faint lines running diagnal no matter how long the TV is on for.
Im trying to figure out if it is my TV or something else.
Could it be dust near/on connections? Connetions themselves.Cables crossing over eachother....
I would hate to think my TV is going out on me already.

The lines are faint but very noticable depending on the picture being shown at the time.Some scenes I can barely see them if at all, other scenes they are right in my face and make even a good HD picture look like crap.

Anyone have any ideas?

Which camera?

Do you see this using the normal SD or HD tuner?

Sorry, had to reboot..
I tried to capture what i see on the TV with my digital camera, but it wont show.
I get the lines with my DVD players as well as the SA8300HD
I see it big time watching SD but still with HD
I have to have a good set of solid colors to see it.Like soeone with a white shirt or a big red background of sorts.Black, it dont show up as much and hard to identify.
