Vertical lines on a TV screen can be caused by a variety of things. Here are some solutions to fix the issue.

The what causes horizontal lines on tv screen is a question that has been asked before. There are many different reasons for the vertical lines on your TV screen, but there are also solutions to fix them.

Vertical lines are unusual to see on a television. When this occurs, it indicates that the problem is caused by an underlying issue.

It may, for example, indicate that the power source is failing or malfunctioning. In other instances, it may indicate that the HDMI cable is not properly attached or that the connection between the processing board and the screen is weak. Another reason may be that the image does not fit the screen perfectly.

When you notice black vertical lines on your TV screen, the first thing you should do is figure out what’s causing the issue. Begin by checking the image, your cable connections, and any external gadgets for proper operation.

You may also try switching stations to see whether the lines show on all of them. Recognize that lines on a TV screen may be caused by either hardware or software.

Troubleshooting software problems is simple. However, if you have a hardware issue, you’ll need to contact the device’s maker or a specialist.

Getting rid of vertical lines on your TV screen

Here are a few options to consider.

1. Restart your television.

By simply power-cycling a TV, you may remove black vertical lines from the screen.

  • Turn off the television.
  • Remove the power cable from the outlet.
  • Allow at least two minutes to pass.
  • Reconnect the power cord.

After that, switch on your television to check whether the problem has been resolved.

2. Double-check cable connections

A defective cable or one that has not been properly attached to the input or output ports may cause the signal to be disrupted, resulting in vertical or horizontal lines.

Consider the following:

  • Make sure all cords are secure at both the external device and the television.
  • If you have a spare set of cables, swap them out.
  • Make sure your external device’s image format settings are the same as your TV’s.

Lines may also appear if your external device is malfunctioning. A Blu-ray player, game console, or set-top box are examples of external devices.

You’ll have to repair or replace the gadget if it’s broken. Try a different device to be sure it’s not the one that’s creating the issue.

3. Examine the image settings

A green line on a TV screen may be removed by adjusting the image settings.

Most TVs include options that influence image presentation, such as aspect ratio, screen resolution, and horizontal or vertical scan frequencies. In this situation, consult the user manual for the external device to modify the image format settings.

Also, make sure the image format settings on an external device match those on your smartphone before connecting it. Set the source on your TV to the same port that your game console is connected to. If your console is connected through HDMI port 1, your TV’s source should be HDMI 1.

4. Update the software on your television

The gadget is controlled by the software on your television. An out-of-date software package may result in a variety of issues, including vertical lines, poor image quality, and the inability to install applications.

Update the program to see if it fixes the problem. For instructions on how to update the software on your television, see the owner’s manual.

5. Reset your television to its factory settings.

A TV may fail to process a combination of picture settings you’ve given in certain circumstances. This may result in a variety of visual issues, including flickering lines on TV. While you may go through all of the settings one by one, resetting your smartphone is a better option.

Resetting your TV to factory settings should only be used as a last resort. This is due to the fact that it will delete all of your data, including your settings. On the plus side, it enables you to start again.

6. Inspect the hardware of the television for any signs of wear and tear.

Vertical lines on an LCD panel may sometimes indicate a faulty T-Con board. The T-Con (timing control card) regulates the display of pixels on the screen. The only option if your T-Con board is defective is to fix or replace it.

You may replace the T-Con board with a new one by removing it yourself. However, if you select this option, you must be cautious not to damage anything on the television.

The best option is to get assistance from a professional. If your television is still under warranty, contact the manufacturer for further information.
