When the vertical lines appear on your TV screen, usually it happens because the flat cable did not connect to T-Con Board. T-Con is an abbreviation of Timing Control in LED TV.

The Timing Control itself has a function to turn of and turn on the LED or LCD panel on your TV. If it is broken, your TV’s image quality will suffer.

To check on this problem, you can knock on the backside of your TV. If you knock it hard enough and the vertical lines on your screen are gone then it is because the T-Con Board is loose.

However, if this problem still exists then it will be 100% due to the flat cable that is connected to T-Con Board is broken. There are also a number of problems that could affect the T-Con such as:

The cable which connect T-Con modul and display panel is not connected or break. The causes can be because the connector cable is dirty or rusty.
The voltage in T-Con is gone. If there are vertical lines, then it is very likely due to the lose voltage with Multi Channel Power Supply TFT Panel.
The gamma is broken, hence why the color that appear is only black and white.
IC Scan Driver is broken, hence why the vertical lines appear.
If these are the reason, then the only thing you can do is to change the component with the new one. The loose connector cable can also be the reason, it is usually located in the back of the TV.

If this cable is loose or damaged, it can create distortion to a half or even all TV screen.

Make sure that all the cables are connected properly. You can always disconnect and connect it again to see if it give you a better result on your screen.
