How To Fix A Line Of Stuck Pixels On A TV

Besides our mobile phones, TVs are probably one of the most common devices that we interact with on a daily basis.

Whether you’re a home theater enthusiast, or just the every day person that enjoys a good show from time to time, watching TV can be a fun experience.

However sometimes these devices can unfortunately experience issues.

Whether it’s from an internal defect, or not taking into account proper maintenance, some TVs may occasionally encounter an issue with their display.

More specifically, the pixels in the display themselves might stop working or appear stuck.

So is it possible to fix a line of stuck pixels on a TV and more importantly, how do you do it if so?

Let’s find out.

How To Fix A Line Of Stuck Pixels On A TV

Using a specialized digital test pattern, turning the TV off/letting the panel rest, trying a different cable/HDMI port, & cleaning the screen with a microfiber cloth are different things that may help with stuck pixels. Keep in mind though there’s no guarantee they’ll work since it specifically depends on why it’s happening with your TV in particular.


What Exactly Is A Stuck Pixel and How Is It Different From A Dead Pixel?

So the first thing I want to do is make a differentiation between a stuck pixel and a dead pixel since there can sometimes be confusion between the two.

Anyways just to recap, a pixel is what makes up the television screen and the combination of these helps to display the image.

In the typical display, every pixel is made up of the colors red, blue, & green, and the more pixels that exist in the screen, the higher the resolution.

That said, of course there’s also special display technologies where there may be additional colors used to achieve a wider color gamut, but red, blue, & green is what’s traditionally used.

Now here’s the thing, when a pixel experiences an issue, besides the brightness of the pixel itself dimming, one of 2 things may happen; either it gets stuck displaying a single color, or it doesn’t turn on at all.

When the pixel doesn’t turn on at all, this is known as a dead pixel and will present itself in the form of a tiny black square.

This can happen for a number of reasons which we’ll get to in a bit, but when the actual pixels themselves give out, there really isn’t a way to fix it outside of replacing the panel.

The thing that might fixable is what’s known as a stuck pixel, and this will basically look like a small dot that’s a different color than the pixels around it on the screen.

Like the name suggests, it’s a pixel that’s stuck showing a specific color even when the content on the screen changes.


Why Does This Happen Though?

Why do pixels fail or even become stuck? Well it could be for a number reasons, but here’s a few reasons that I think could factor into this happening..

Placing A TV In Less Than Ideal Conditions

The first thing that I personally think could affect this is placing your TV in less than ideal conditions.

More specifically, you don’t want to place your TV in places where there’s drastic temperature changes or lots of humidity or moisture.

If the room gets too hot, then it could cause the TV overheat over time, and if it’s too cold, then it could affect the panel.

Not to mention there’s the risk of condensation forming when the TV warms up and there’s a big temperature difference between the display and the room.

Places with lots of humidity or moisture also isn’t a good idea since there’s the risk of moisture forming in the internals of the television which could lead to some abnormalities happening with the display.

So placing your TV in dry and room temperature conditions can certainly help with the wellbeing of the set.


The Age Of The Television

The second thing that could have something to do with a pixel becoming stuck is that the television itself might be getting old.

TVs can certainly last for a while, but if you feel the TV is somewhat old, then it could be a result of the fact.

Now how long a TV lasts is going to vary wildly since it’s dependent on build quality, how well the TV is maintained, how long it’s on daily, etc. but an older TV could experience issues and this might be one of the ways it happens to manifest itself.


An Internal Defect

Whether it’s a speaker, a TV, or just a tech product in general, sometimes defects can just happen.

Whether it develops over time, or has always been there and you only recently noticed it, it’s certainly possible for there to be a defect with the screen even if in the form of issues with a few pixels.

The Panel Is Accidentally Damaged Somehow

Another reason why this could be happening is the screen was recently damaged somehow.

Whether the TV was subjected to extremely high heat, impacted by an object, or even dropped, the panel itself is very sensitive and any kind of stress to the screen can cause problems to develop with it.

This is why proper maintenance of the TV is paramount when it comes to longevity overall.


Using An Extremely High Brightness Setting

Sometimes televisions can be set at their brightest settings right out of the box – and while is used in stores when there’s really bright lights present, at home isn’t always ideal when it comes to optimal picture quality and longevity.

Leaving the TV at a really bright setting not only could contribute to burn-in or image retention when it comes to OLED displays (when a portion of pixels show a prior image that remains on screen) but could cause the TV to get hotter — which could also eventually stress the panel in some way e.g. (stuck pixels forming)

Not to mention a high brightness can cause blooming on portions of the screen as well.


How Do You Fix A Line Of Stuck Pixels On A TV?

So with all of that said, is there a way to fix a few or even a line of stuck pixels on a TV?

Well here’s the thing, it really depends.

It depends on whether the pixel is simply stuck or has failed, if the surrounding pixels still work, if the panel itself still properly functions, etc.

So while the following are a few suggestions, keep in mind there isn’t a guarantee that they actually work nor are they definitive since it specifically depends on why it’s happening with your TV in particular.


Using A Specialized Test Pattern

So the first thing that you can try that may help is using some sort of specialized digital test for the pixel. These digital tests usually involve changing different colors or patterns to try and get the pixel to respond by changing from whatever color it’s stuck on.


Seeing If The Problem Resolves On Its Own By Letting It Rest

Another thing that might help is simply time and letting the display rest.

Whether the TV became too hot internally, or it was some kind of glitch, it might be worth it to turn the TV off for a bit and letting it rest to see if that might help.


A Different Cable Or Port

It’s always possible to try a different HDMI cable or even port to see if that helps since a faulty/defective cable or port could present itself in the form of some kind of glitch with the content being displayed.

Actually Determine If It’s A Stuck Pixel Or Something On The Screen

This goes back to the importance of properly maintaining the TV since a speck of dust or something on the screen could look like a stuck pixel from a glance or distance.

Cleaning the screen with microfiber cloths and/or with a specialized TV solution can help with determining if it’s actually a problem with a pixel or just something on the screen itself.


Having The Panel Replaced/Repaired

Finally while certainly more involved, it’s possible that something went wrong with one of the internals of the display, and having it replaced/repaired might be an option.


Final Thoughts

That about does it for this one.

Stuck pixels can happen for various reasons, and may sometimes never go away; or may resolve itself on its own or through one of the ways mentioned prior.

Keeping your TV in a dry room at a moderate temperature can also help with avoiding moisture that can lead to issues with panel.

Not cranking the TV to maximum brightness at all times may help in that regard too since any overheating could present itself in the form of abnormalities with pixels on screen.

But that wraps it for this one.

Until next time, make it easy, keep it simple.
