LG TV Vertical Banding Causes and Fixes

Those vertical colored bands you see on your LG TV can be caused by many reasons. Knowing the exact cause of the problem is the first step to fixing it. 

Here are the most common causes of vertical banding on LG TV and the best ways to fix each:

1. A Problem With the Video Playing

Depending on the video playing, colored bands can appear if the video contains a large mixture of colors. These can overwhelm your smart TV.

Fix: Reset Audio and Video Settings

The first thing you should try is resetting the video and audio settings. If it doesn’t work, you can try resetting your LG smart TV altogether. 

2. A Problem With the Video Source

Shifting between channels, video sources, and inputs, if you see the vertical banding on some channels or inputs and not others, you’ve got a problem with a specific channel or input source.

Fix: Remove Anything Hindering or Blocking the Satellite’s Signal

Firstly, check the channel signal strength. This would tell you if there are any problems with the channel itself, which will then have nothing to do with your satellite connections.

If the channel has a strong signal, check your antenna or satellite dish for anything that might be blocking their signal and remove it.

3. A Problem With the Cable

If the vertical bands persist throughout all channels, try playing videos from another input. If the bands remain on videos playing from other input sources, there may be a problem with your TV input board or input cable.

Fix: Reattach or Replaced the Input Cable

Check your input cables for any visible damage. If you find any damaged cables, replace them before trying your TV again.

However, if your input cables don’t show any visible signs of damage, check if they’re attached correctly. Remove all input cables and attach them one by one to check if any specific cable is damaged so you can replace it.

You might even notice that the problem is no longer visible after properly reattaching the input cables.

4. A Damaged Input Board

If you’re still seeing vertical bending on your LG TV, your input board may be malfunctioning or have suffered some damage. 

Fix: Reset Your LG TV or Replace the Input Board All Together

The TV’s input board might face some software mishaps from time to time. Resetting your LG TV would fix any temporary problems with the input board.

However, if the vertical banding persists on your LG TV screen after resetting it, you might have a damaged input board that would require replacing. In this case, you should request a repair service.

5. A Problem With the Screen Itself

A screen problem would appear as vertical banding that is constant throughout different satellite channels, videos from external inputs, and applications. This could be a software or hardware screen problem.

Fix: Check and Troubleshoot Software or Hardware Screen Issues

As with any software breakdowns, try resetting your TV to the manufacturer’s settings. This is enough to fix any temporary software troubles. 

If the vertical bands are still visible after you rest your TV, you might have a problem with the screen’s hardware or a permanent software breakdown. If that’s the case, resort to LG’s repair service. 

6. Software Update Needed

If it’s been a while since you updated your smart TV’s software, it may start acting up. Outdated software can cause image issues like vertical banding. 

Fix: Update Your Smart TV’s Software

To update your smart TV’s software, all you have to do is ensure a reliable internet connection and follow the manufacturer’s manual. 

Try a soft reset

Often, a soft reset will solve issues on LG TVs. To soft reset the TV, simply take the plug out of the wall outlet and wait for at least 60 seconds. If that does not work, it would be worth factory resetting the TV, but this will completely reset all of the data stored on the TV to its factory defaults.
