When you see lines on tv screen vertical, it’s often an indicator that something is wrong. Whether they are straight or moving, it could mean that the internal parts of the TV are faulty.
Luckily, you can usually fix this yourself without spending too much time. The first thing you should do is reseat any physical cables, then try restarting the TV.
Loose or Damaged Cables
If the lines on your TV screen appear wavy or move around, it could be a sign of a loose cable connection. Reconnecting the cables may resolve the problem. You should also try changing the source if you have any external devices like a Blu-ray player or game console attached to your TV.
If you have a loose wire connecting the T-Con board to the LCD panel, it can cause vertical lines on half or all of your TV screen. Knocking or tapping on the back of your TV may temporarily fix this issue, but you will need to replace or repair the cable for a permanent solution.
You can also try resetting your TV to see if it fixes the problem. This can resolve minor software issues that could be causing the lines to appear on your TV screen. If these steps don’t work, you should contact the manufacturer for further assistance.
Damaged T-Con Board
The T-Con Board or Timing Control board is an essential part of your TV. Its main function is to turn the LED/LCD panel on so that it can bring up images. Its shape varies by TV manufacturer, but it is usually located at the bottom of the screen. If this board is damaged, it can cause vertical; colored lines on your TV’s screen.
To repair a damaged T-Con board, you’ll need to remove the back of your Samsung TV. This is not easy, and it requires careful work to avoid damaging the components inside. You’ll also need a screwdriver and a flat surface to lay the TV on. Before you start working, be sure to discharge any capacitors on the circuit board by using a capacitor discharge probe.
After discharging the capacitors, you can begin by removing all of the screws on the back cover. Next, place the TV on a flat surface and face it down.
Rust on the Frame
A TV’s screen can get damaged by various factors such as water flowing inside, falling on the floor, or hitting against a solid object. These issues can cause vertical lines to appear on the screen, which can be very annoying. In this case, it is important to take the TV to a maintenance specialist for repair.
The problem may be caused by rust on the metal frame. This rust can spread to the flat cable or the T-Con board, causing distorted images on the display screen. In this case, it is recommended to replace the T-Con board or get a new LED TV. It is also possible that the rust is causing the TV to overheat, which can cause the screen to produce vertical lines. To fix this, unplug all devices connected to the TV and try using a different source to see if the lines disappear. If the problem persists, consult a technician for further troubleshooting.
Software Issues
Sometimes it can be tricky to pinpoint the source of those pesky horizontal lines on your TV screen. The first thing you should do is run a picture test on your television to determine whether the problem stems from an external device or connection.
Check all HDMI and AV cables to ensure they are properly seated and that there is no oxidation on the contacts. You can also knock on the back of the TV to see if it changes the image. If it does, then the issue is likely with the T-con board or the tab bonds connecting it to the LCD / OLED panel.
In some cases, the lines may be caused by a software issue that can be fixed with a simple reset of your TV. To do this, follow the steps below:
