Samsung LED TV vertical lines on the Screen are a common issue caused by various factors such as a faulty T-con board, damaged Screen, or loose connections. These lines can appear as single vertical lines or as a series of lines that span the entire Screen. They can be distracting and negatively impact your viewing experience.
It’s important to identify the cause of the problem to determine if the issue can be fixed or if the TV needs to be replaced. In some cases, it may be possible to fix the issue by adjusting the settings or replacing a faulty component, but in other cases, replacing the TV may be more cost-effective. Here we will discuss ways to fix Samsung Led TV Vertical Lines on the Screen.
What Causes Vertical Lines on Samsung LED TVs?
Several factors, including hardware and software issues, can cause vertical lines on a Samsung LED TV screen. The following are some of the most common causes:
- A damaged cable or loose connection: The cable that connects the TV to the device (such as a cable box, DVD player, or gaming console) can become damaged or loose over time. This can cause vertical lines to appear on the screen. To fix this, check the cable connection to ensure it is secure and not damaged.
- TV hardware issue: If the vertical lines persist even after checking the cable connection, it could be a hardware issue. This could be due to a damaged panel, malfunctioning video processor, or other hardware component. A repair by a professional may be necessary to resolve this issue.
- Overheating: Overheating can cause the TV to malfunction, resulting in vertical lines appearing on the screen. This can be due to poor ventilation around the TV, a malfunctioning cooling system, or prolonged use. To prevent overheating, ensure the TV has adequate ventilation and avoid using it for extended periods.
- Firmware issue: In some cases, a glitch can cause vertical lines to appear on the screen. Updating the firmware may resolve the issue. To check for a firmware update, visit the Samsung support website or contact Samsung customer support.
- Electrostatic discharge: Electrostatic discharge can damage the TV components and cause vertical lines to appear on the screen. Avoid touching the TV screen or other components with your bare hands to prevent this.
- Malfunctioning T-Con Board: The T-Con (Timing Control) board is a vital component in modern LED TVs, responsible for processing the image signal from the mainboard and controlling the display panel. A malfunctioning T-Con board can cause various display issues, including vertical lines on your Samsung LED TV. The causes of a Malfunctioning T-Con Board are Manufacturing defects, Overheating, Voltage fluctuations, Damage due to power surges, Component failure, or wear and tear over time.
- Failing Display Panel: The display panel is the heart of your Samsung LED TV, consisting of millions of pixels that produce the image you see on the screen. Over time, the panel can degrade and develop problems, leading to vertical lines and other display issues. The causes behind the failing display panel are Manufacturing defects, Aging and wear of the display panel, Physical Damage, such as impact or pressure on the screen, and Faulty ribbon cables connecting the display panel to the T-Con board.
- Signal interference: In rare cases, external signal interference from nearby electronic devices might cause display artifacts, including colored vertical lines.

LCD Panel Function on the LED TV
Now, before we move to the repair stage, maybe some technicians do not know what the function of T-Con in LED TV is. The icon stands for time control, by the meaning you already know, right? So the function of this module is to control the image formation time.
If you assume a CRT TV, this Tcon is a deflection yoke used to reflect the image vertically and horizontally. On the LED TV, displaying images predominantly vertical is the task of the T-Con plate. The faint vertical lines on Samsung TV can be synonymous with that the problem just appearing and having a prompt solution.
The following are the T-con functions on the LED TV:
- Remote control functions to turn on the LED / LCD panel so that it can display a picture.
- As Timing Control pulse generator which can be generated from the IC Scan Driver
- Multi Chanel TFT Panel power cord to supply voltage to the source driver and gate driver amplifier circuits.
- Grayscale (gamma) Plant
- The shape of the T-con board varies greatly depending on the brand of TV.
But, indeed, its position is always at the bottom of the LED panel.

- Voltage VGL or Voff: generally around minus 7 to minus 15 V
- Voltage AVdd for Gamma IC reference in T-con modules: generally, the voltage is around 15 to 18v.
