Sony KDL52VL150 CCFL LCD - lines in picture
Screenshots of problem here in the post.

Picture of screen with both cables to panel from TCON connected, and the other is with one side disconnected.

I have read the cables from the TCON to the display loosen up on the end to the panel. I believe as I am working on moving the cables around, the picture is improving 
and getting clearer. So I think thats the problem. Someone mentioned using tape over them to hold them to the panel better. I have not taken the metal frame off to 
look at them, but there is a narrow gap where I read some people stuff cardboard in there to press down on them better.

Has anyone ever seen this issue and come up with a good way to resecure the cables?
