First of all let me answer a common question, can an OLED TV ‘burn in’ be fixed?
And the short answer is yes, it is possible to fix a 'burn in' when it is a image retention.
However, I have to clarify that there are two kinds of image retention:
- Temporary (Software)
- Permanent (TV hardware)
With that said, a hardware or permanent 'burn in' can only be fixed by replacing the damage part. And that is usually done by replacing the entire TV screen panel.
What is the TV defect known as 'burn in'?
'Burn-in' refers to this gradual degradation of pixels. When a static image is left on the screen for a long time, the panel tends to 'hold it'.
It is not unique to OLED displays - CRTs, LCDs and Plasma are all susceptible to some degree.
The cause
Like I said, leaving a fixed image on the screen for a long period of time can cause image retention. But it can happen naturally by displaying high-brightness text and images for long periods of time or repeatedly.
It causes uneven degradation of the pixels that make up the display as there will be a difference in brightness between the area covered and the other area. In other words, regular use of certain pixels more than others will leave them displaying colors slightly differently.
It’s possible that minor distortion or discoloration appears in just a few hours, even on the latest devices. So manufacturers usually test ALL their TVs before shipping.
LG tests them for about 72 hours:

How to fix OLED TV ‘burn in’
How do I know if my TV screen has a ‘burn in’
How do you know? That's usually easy to spot it.
If you change channels and an image of the logo or banner remains on the screen, it is image retention. It may appear as a 'ghost', 'shadow' or 'stain'.
- If that ghost disappears over time, it's just temporary.
- If the ghost doesn't disappear, you may have a permanent defect.
The defect may not be easy to detect, so you may need a more technical approach.
In this case you should run a burn-in test, a video that helps you spot discoloration in your screen.
A solid red pattern is usually the most effective way to carry out the verification. If you have any other colors, you may have burn-in:
Tip: Run this video on your TV (You may mirror it if possible).
If you have a temporary image retention, you have a few options:
- Pixel Refresh
- Panel Refresh
- Other app
- Wait to see if it goes away
Pixel Refresh and Panel Refresh (Or other app)
'Pixel refresh' is a feature that may fix image retention. This feature does it by using different brightness and colors in each pixel in order to get the pixel back from its 'stuck' state.
It may be manually or automatically activated.
On Sony TVs the feature is called 'Panel Refresh' and LG calls it 'Pixel Refresher'.
I talk about it in this article:

'Burn-in' fixer
There are a number of burn-in repair apps. They will try to fix image retention. I recommend you stick with your manufacturer's tools.If you really don't want to spend on apps, you can use a video that flashes different colors.
Do not watch it if you are sensible to fast color change:
Wait to see if it goes away
Well, give it time. The thing is, OLED screens should not run continuously.
So, just let your TV rest for a few hours.
Then go watch varied content. By the way, try turning down the brightness and contrast on your TV.
The problem may go away on its own.
Permanent image retention
You may need to replace your entire panel or device in order to resolve the problem. If you are looking for parts:

Tip: Check if the warranty covers it. Also note that the TV replacement may be more expensive than buying a new TV.
How to replace your TV panel
Tip: Turn on the caption button if you need it. Choose “automatic translation” in the settings button, if you are not familiar to the english language. You may need to click on the language of the video first before your favorite language becomes available for translation.
LG OLED display repair costs
Some claim that an OLED TV repair cost somewhere between $100 and $400.
How to prevent a ‘burn in’ in your TV (Prevention tips)
Avoid static images
Most manufacturers will say that the best way to prevent burn-in is to avoid static images.
So tip number 1 is avoid leaving static images on an OLED screen for long periods of time.
Use the manufacturer's tools
Use the burn-in mitigation technology included in your TV. According to LG:
There are three options (available in Menu setting > Picture settings > OLED panel settings) that can be used to preserve image quality.
The first of these is the Clear Panel Noise feature that preserves the quality of the image on the display panel by resetting the TV so that it clears the pixels. This feature can be turned on when needed within the settings mentioned above.
The second feature that can be employed is the Screen Shift feature which, moves the screen slightly at regular intervals to preserve image quality.
A third option is the 'Logo Luminance Adjustment', which can detect static logos on the screen and reduce brightness to help decrease permanent image retention.

I would also like to add that:
- You should run their 'Auto refresher' feature when they request it. Some require it to run every 2000 hours of watching time.
- You can set “Logo Luminance Adjustment” to “High” to darken static areas of the screen.
Adjust the brightness
Lowering your brightness setting to below 80 could reduce any burn-in. Choose 50 if you want to be extra conservative.
There are, however, ways to prevent this failure: avoiding static images on the screen for a long time, investing in more modern devices and opting for display modes with lower brightness intensity contribute to relieving the stress on the millions of LEDs that make up these panels.
Pixel shift
OLED TVs from brands like LG and Sony include pixel-shift technology that constantly moves the image slightly to vary pixel usage.
Reduce your screen's timeout length
Make sure your screen is turning off in less than 30 seconds to prevent static images from lingering.Use dark mode
This setting emits less light and uses fewer pixels, allowing your screen to relax.Screen Saver
Always use the Screen Saver feature if it is available.
It will turn on automatically if the TV detects that a static image is displayed on screen after a while.
Other unofficial tips:
Automatic shutdown
Some TVs allow you to turn off automatically after a period of inactivity. It is like in your computer:
- X minutes will trigger a screen saver.
- Y minutes will trigger a TV power off.
First hours of use
Some technicians reported that:
To prevent burn-in from affecting your television, it is necessary to “soften” the screen between the first 200 and 500 hours of use.
To soften the television, use only half of the set's contrast and brightness capabilities and avoid watching static images for more than 30 consecutive minutes.
Wallpaper to white (LCD)
There is also a method to eliminate burn-in on the LCD screen by using white wallpaper, which is a color that is easy to apply voltage to the LCD screen.

Now I'll leave a few frequently asked questions:
What are the most common OLED TV problems?
First let me quickly define an OLED TV.
What is OLED
OLED is a self-emissive technology, which means no backlight is required. They produce exceptionally rich colors and deep blacks, due to the self-illuminating nature of each pixel.
One of its many qualities:
- Perfect blacks (Color).
- Excellent contrast ratio, viewing angles and response times.
- Energy-Efficient.
However, OLEDs have one major drawback: screen burn, which is when the organic pixels in an OLED TV become permanently unable to display something other than a specific image.
Each pixel generates its own light, which will gradually dim over the course of a product’s lifespan.
The main downside of OLED displays is the risk of screen burn-in, which causes static parts of the image to be permanently 'burned' in the screen if the same content is displayed for excessive periods.
However, there are ways to prevent it.
Typical OLED TV problems
- Average Brightness Levels
- Water can easily damage OLEDs.
- Lifetime (OLED TVs Are Susceptible to Burn-Ins).
- Not recommend to be used as monitors.
Do OLED TVs get 'burn in'? Are they exclusive to OLED screens?
OLED do get 'burn-in' as does other types of displays like:
- CRT TV
- LCD TV
- LED TV
- Plasma TV
They are all susceptible to some degree.
Why are there no OLED monitors?
First of all, there are OLED monitors. And an OLED TV can be used as monitor.
The are two main reasons why OLED monitors are not popular is:
- Lower lifespan: OLED screens are susceptible to 'burn in' when used for longer periods of time. And monitors are used under this condition.
Due to the risks, few companies decide to manufacture it.
- 'Refresh rate' limits. Gamers love high refresh rates and OLED monitors can't provide it (yet).
Help! There is a ghost in my OLED TV. How do I fix ghosting?
The most common fix for monitor ghosting is to turn on the overdrive function.
Response time overdrive allows you to push the monitor's response time speed (pixel transition time) in order to decrease the trailing/ghosting artifacts behind fast-moving objects
