Question about Samsung LE40R74BDX 40 in. LCD Television

1 Answer

I have a Samsung LE40R74BDX. A thin white line has appeared on my television across the middle of the screen. It only appears when I am watching anything in HD, such as when I'm using my Xbox. When I watch anything in SD the line disappears. Can anyone help?

If the line is there whatever the source of the HD signal and whatever the image then the problem is inside the image processor - a line from the memory bus is fried and not read. The entire board must be replaced and it will cost you around $100.
This is really a job for a pro so take your tv to a repair shop.

Lines down screen


We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

My toshiba laptop has a thick white line down the screen


The normal cause of lines across the LCD of a laptop is a damaged video cable. The unusual cause would be the video card itself.

To determine which item is at fault, you need only attach an external monitor to your laptop's video-out, and then swap your monitor view to 'both' or mirrored (usually just the function key (FN), plus one of the Fkeys...look for an off-blue picture of a monitor on the Fkeys).

If the lines across the screen also appear on an external monitor, then the video card is damaged.

If the lines only appear on the laptop's LCD, but not the external monitor, then just the laptop's internal video cable is damaged.

Hope this helps.
