Lines can be caused by a number or things: bad main board (control) which is rare, bad or loose plugs or solder connections.

The worst case is the issue (connections etc) can also be inside the display panel (PDP or plasma display panel) where they cannot be got at.

Parts for brand listed are not real easy to find in some cases.

this is a buffer issue.

do the line go through the menu if you display the menu when the lines are visible?

do the lines go from the top to the bottom of the screen or stop halfway there?

do the lines change colors?

if the lines go over the menu and all the way down to the bottom of the screen, then its a buffer issue, top and bottom buffer.

hopefully it's just halfway then you only have to replace the top buffer, less money to spend.

Insignia(samsung) 50" plasma Vertical red lines


I would take it back. I know from purchasing an Insignia LCD from them a while back, the TV just died after about 4 or 5 months. They ended up offering me another TV or with store credit. I took the store credit and chose another TV. I also did not have a warranty. I was told since it was Insignia (which is a Best Buy house brand) that replacing it was not a problem. Good luck.
