Flat panels tv's use memory to paint picture on the screen. If the chips are bad, you'll see lines, checkers etc.

SOURCE: Lines across screen breaking picture into 4 sections

Based on reported problems with Samsung LCD tvs, It is probably one of three problems:
Separation of layers of the LCD panel;
A defective LVDS cable connection;
A defective T-Con circuit board.
If light hand pressure on the affected area on the LCD panel changes the problem, its the defective panel. If not, manipulating the LVDS cable will reveal the cable defect. If not, coolant spray applied to the T-Con circuit board should reveal if it is defective by temporarily alleviating the problem. Dont remove the back cover if you dont know how to protect yourself from electrical shock hazards. There can be more than 1000 volts in the backlight inverter area.

Horizontal lines across screen of sony KDL-46BX450


Sounds like a T'Con fault itself. Re-seat all the incoming and outgoing flat cable wires to T'Con. If it do not help you, replace it with a new one of same part number. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

Thin horizontal line across screen


Hello
You haven't specifed nothing about the model number or brand name of your flat panel teleivison. i assumes that it to be a picture tube based one and posts this solution before you.
A thin horizontal line across the screen with sound output is OK, is the sympton of total failure of vertical sweep. This may be due to failure of vertical output IC or loose solder terminals of that IC. The vertical output IC will heat up while working, and repeated heating and cooling may make its solder terminals to get loose. Just open your TV, pull out the board that contains vertcial output section, turn it upside down, resolder all the solder terminals of that IC by applying a little more solder, without making any solder bridge in between terminals. Check the voltage to the vertical output IC also. If this resoldering method does not help you, replace the vertical IC itself with same type and number will solve your TVs problem. OK.
