Why is There a Dark Shadow on My LG TV?

As a frustrated LG TV owner, I recently noticed a dark shadow on my TV screen. After doing some research and testing, I decided to write this blog post to share how I solved the issue, as well as other potential solutions I discovered.

Dark shadows on a LG TV are caused by burn-in, stuck pixels, and weak Wi-Fi signals. You can fix dark shadows on a LG TV by leaving the TV off for a day, playing a regular channel for 8 hours, or making sure your TV has a strong internet connection. 

Stuck pixels and burn-in have plagued TVs since the dawn of LCD screens, but it has gotten easier to fix them. Here’s what you need to know about getting rid of those dark shadows on your LG TV.

Why is There a Dark Shadow on My LG TV?

The dark shadow on your LG TV might be caused by one of three things including stuck pixels, burn-in, and a weak connection.

Stuck Pixels

LCD TVs can get stuck pixels when the visual information on a pixel doesn’t update and the color of that pixel can get stuck.

Sometimes, these pixels can be revived by playing channels that often change the picture on the screen.


Burn-in can be caused by having a single image being on display for a long period of time which eventually gets “burnt” onto the screen. 


LG TVs can also have a problem where they display vertical “shadow”, usually when they have a weak connection. This is due to how Sharp smart TVs display streaming content like movies and TV shows. 

How to Get Rid of the Dark Shadow on My LG TV?

There are a few quick steps to remove a dark shadow from a LG TV.

Your first step should be to unplug any inputs and then turn the TV off for at least three hours.

Then you can try to play a YouTube, or other, video of just static to try to unstick the pixels. You can also try playing a normal TV channel for 8 hours to unstick the pixels. 

Turn Your TV Off For a While

You can try to get rid of a black shadow on your LG TV by just turning it off for a while. This helps to reset the pixels and remove any burn-in that could be causing your static.

Modern TVs can also get shadows from glitches which can be helped by a hard reset. 

Set The TV To Play Static

LCD TVs can get one of two issues that can cause shadows.

One of them is burn-in which is when an image stays paused for too long and gets “burnt in” to the screen.

Then, there are also stuck pixels which is when single pixels, or groups of pixels, get stuck on a single color. 

Turning your TV to static for a few hours can unstick these pixels and get them to display the right visual information. 

Play a Normal Channel For Eight Hours 

Leaving your LG TV on a normal channel can also fix shadows, stuck pixels, and potentially even burn-in. You need to find a channel that is going to play a varied amount of visual information.

This means looking for a TV station that is going to play shows that have a lot of color and various levels of darkness. 

You should avoid trying to play the same movie or show on loop as this could make the burn-in worse if the TV gets stuck while playing. 

Soft reset the TV

To soft reset the TV, unplug it from the wall outlet and wait for 60 seconds before plugging it back in again. Doing this resets the internal cache of the TV.

Factory reset the TV

If none of the above works, it would also help to try factory resetting the settings of the TV. It could be the case that there is a setting on your TV that is causing the issue.

Why is There a Vertical Shadow on My LG TV?

The vertical shadow on your LG TV can either be caused by burn-in or a weak signal. Burn-in can be corrected by playing static or a regular TV channel for several hours. The weak connection can be fixed by ensuring that you have enough bandwidth, a good Wi-Fi connection, and that nothing is interfering with your TV. 

What Causes Vertical Shadows on LG TV?

The vertical shadow on a LG TV is different than other visual issues you could experience. While it might be caused by burn-in like other problems, it is most likely to be caused by a bad connection.

LG TVs can often display these vertical shadows when they can’t get enough information about the content they are currently playing.
