Hi there! If picture is smaller top to bottom with blank section on top and bottom then check your aspect ratio settings. If blank at the bottom only the Bottom Y-Drive board may be faulty. If blank at the top The Top Y-Drive may be faulty. If blank on the Left (TOP TO Bottom) then the Right X-Drive Board and on the Right, the Left X-Drive Board. May also be bad connections on the cables or flexible ribbon cables. Best Wishes and Good Luck, JUS004

Black line on middle of screen

Hopefully you still have under warrantee. If not, sorry. This line if memory serves me right is because the tv has 2 picture panels on each side of the TV (they join up together to make one picture). Toshiba did not realize that the panels will start slipping thus creating this fine line from the top of the screen to the bottom. They have revamped the newer models and placed glass to adhere the panels together. Even though my TV was under warrantee I got a new one and have had this one for 1/2 year and now the picture just blew (there is sound but no picture.)
Take your TV back if it is under warrantee.

Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad
