how to repair scratched lcd screen factory

Windex, Brasso, or any other solution which contains ammonia, or any other solvent including acetone, will damage ARAG (anti reflective , anti glare) coatings or films.

Few CD/DVD repair fluids can be used to fill or smooth over small scratches or scrapes in the plastic-like first layer of anti glare films. This is because some fluids contain solvents and/or abrasives.

You can also use Pledge or some similar wood polish: It will fill in the scratches on computer monitors or CD"s. However, it will leave discoloring blemishes, often more objectionable than a scratch. Petroleum jelly has the same effect, and is much harder to remove. Plastic model glue has irreversible negative effects.

Welcome to a guide on how to remove scratches on computer screens. Oh no! There is an ugly scratch mark on the screen, and it is very annoying every time you use the computer. Fear not. If the scratch is not too deep, there might still be hope with some “home and Internet remedies”.

A short disclaimer though. While I have personally tried and tested some of these methods, they are not proven to be 100% effective. But in any case, there’s no harm in trying out some of the “low risk” possible fixes – Read on!

Erasers are one of the most common and easy “remedies” that we techies use. Just use a soft rubbery pencil eraser (not those rough abrasive types) to gently rub on the scratch mark – It seems to work pretty well in removing light scratches, and it cleans off stubborn pieces of stuck dirt as well.

Have a very dirty screen with a lot of small scratches everywhere? Then you will need to get a cleaning cloth, some cotton buds, a soft brush, and cleaning alcohol (90% isopropyl alcohol from pharmacies will also do the trick).

First, apply the alcohol evenly over the screen. Be careful of the edges around the screen, and not get the alcohol inside – It will damage the electronics. Wipe it down with the cleaning cloth, and use cotton buds to target stubborn spots. This should pretty much restore any old screens back into their “shiny state”.

Note – I know the above is not a “scratch repair” video, but that is a very good demonstration of how to restore an old computer screen using cleaning alcohol.

There are actually quite a lot of these “Mythbusters” videos on the Internet that toothpaste does not remove scratches. Personally, I have tried it and it works – But only on micro scratches.

Lastly, apply the toothpaste to the screen, use a cleaning cloth and rub it in a circular manner – The whole idea is to use the toothpaste as a screen polish.

This is another trick that we techies use to hide the scratches, and yep, just about any petroleum jelly-based product will work. All we need is to gently rub the cream into the “scar”, it should start to “blend in” and fade the scratch mark. Take note though, that it seems to only work on matte plastic screens and not the glossy glass ones.

This is kind of an “enhanced method” of the above windscreen polish. If there are a lot of micro-scratches on the screen, you can try applying a wet piece of very fine sandpaper (2000 grit) in circular motions to get rid of them first.

Then, complete the treatment with windscreen polish and car wax. The whole process requires quite a lot of elbow grease and patience, but it does restore the screen back to its “default factory shiny state”… Maybe even better.

Once upon a time in the bronze age of the Internet, people would use mashed bananas and baking soda to repair the scratched CDs… A very eco-friendly way of repairing stuff, non-toxic too. If it works on the plastic of a CD, then it should also technically work on plastic computer screens.

Personally, a combination of cleaning alcohol and Vaseline seems to work the best; Cleaning alcohol to remove the gunk, and Vaseline to cover the micro scratches. But take note, this worked on plastic screens, not glass.

If you run your fingers across the scratch mark, and it catches your fingernail. That is probably too deep to be fixed with the above home remedies, and it’s better to replace the entire screen.

Thank you for reading, and we have come to the end of this guide. I hope this has helped you to better understand, and if you have anything to share with this guide, please feel free to comment below. Good luck and may the cyber force be with you.

I just got my NIB WOZ ECLE this evening and have been really enjoying it. After getting my initial games in I decided to update the software and while taking the time to closely examine things I noticed what I thought was a hair on the back glass. When I looked closer I saw that it was actually a scratch on the monitor underneath the glass. When I removed the back glass I could also tell that I was not the first to notice since with the glass off I could see there were smudgy finger prints across the scratch where I guess someone tried to rub it out with their finger. So while it"s a little disappointing that the scratch was noticed at the factory and not handled there I totally understand that things happen it was probably small enough to not trigger any action. After all it"s barely noticeable and had I not been staring at the screen watching the update I probably would never had noticed just playing the game.

So my question is, is there a safe way to remove a scratch from the WOZ LCD screen? I guess it really applies to any LCD screen. The scratch is small (about 1/2" long but deep enough that running a soft cloth over the area i can feel a slight ridge.

LCD screens are fragile and prone to scratches. These scratches cannot be repaired but can be made less noticeable by following some simple methods. We will discuss some of these methods to fix scratches on an LCD.

Take a tsp. of petroleum jelly on a microfiber cloth and buff it across the entire LCD screen. It will give a shine to the screen and will also camouflage the scratches.

LCD (Liquid Crystal Display) screens are known for their clarity, good picture quality, and energy-efficiency. This is the reason they are widely used in almost all the devices, such as computers, TV, mobile phones, etc. These screens are very delicate and must be handled with care. But, no matter how many precautions you take, they are bound to get scratched. These scratches cannot be removed or fixed completely, but can be made less apparent with the help of some simple but effective methods.

Before any fixation, check the LCD’s warranty period. If you are under the warranty, then you will get a free repairing service from the company. In case the scratch is deep and long, then it is better to get it repaired from a professional.

You cannot fix the scratches completely on an LCD TV but you can camouflage them for a pretty good period. Following are some of the methods that you can follow to get the scratches fixed.

Method: Clean the surface with the help of water and cloth. Let it dry for sometime. Now take about 1 tsp. petroleum jelly and fill the scratches. Once all the scratches are filled, take a clean cloth and gently wipe off the extra jelly. You will see that the scratches are lighter, if not completely invisible. You may have to reapply if it wears off.

Method: Clean the scratched area properly with the help of water and a clean cloth. Let the area dry. Now take a clean pencil eraser and start rubbing over the scratch lightly. Rub it along the direction of the scratch. Keep doing it till the scratch disappears.

Method: First of all, prepare a cleaning solution. Dilute 1 part isopropyl (rubbing) alcohol with 20 parts of water. Now clean the scratched area with a cotton cloth dabbed in water. Let it dry. Dip another cloth in the cleaning solution and work on the scratch, cleaning the area gently. Keep cleaning till the scratch disappears. Now take the swab which was dipped in water, and clean the alcohol from the screen. The cleaning solution helps remove the scratch by dissolving the anti-glare coating which fills the scratched area.

Precaution: If the solution starts smudging, then stop immediately. Do not use a strong alcohol. The strength of alcohol should not exceed more than 35%.

You can easily get LCD scratch repair kits in the market under different brand names. These kits are specially made to remove scratches from any LCD screen. These kits generally contain a polishing paste and microfiber cloth. This kit will have simple instructions which you can follow and get the scratch fixed.

★ Do not rub anything against the screen, like a dirty or wet cloth, or any other material that may damage the screen. Even while cleaning, do not apply more pressure.

All the methods mentioned in this HomeQuicks article are helpful in fixing only small scratches. If the scratches are long and deep, then you either need to give it for repair, or get the LCD screen replaced. The best way to prevent scratches is to get an LCD screen protector, which will not only save your screen, but can also be easily replaced in case of damage.

Due to cosmetic errors, a scratched screen on a smart device is not as profitable to refurbish even though the tech is valuable. The cost of replacing a scratched screen is high. But thanks to Mirka’s phone screen scratch repair solution – Remint, you can upgrade the device by removing the scratch in just minutes

I don"t really understand your objection. The blog entry was directly relevant and contained exactly the sort of detail expected on ifixit and contained links back to ifixit. The question was genuine, and my own repair was only attempted when I received no (quick) answer. I am still hoping for a reply explaining how to obtain a replacement rear case or screen.

I did consider contributing a partial teardown of the DMC-FZ18 to ifixit, but because I had to use an old limited camera, most of the photographs were pretty poor. The few decent pictures were on the blog, but that is not very complete. But still useful, I hope, to others with DMC-FZ18s.

A couple of days ago I was cleaning my mousepad and dinged my keyboard into my monitor (DELL S2721DGF), and it got a pretty small but noticeable scratch on it. DELL obviously won"t replace it since it"s not included in their warranty and they don"t do repairs. It really bothers me that the monitor I"m using is scratched, to the point that I"m actually contemplating buying a new monitor. Either a new S2721DGF, or an upgrade to 1440p 240hz, like the Acer XB273UGX.

Am I just an idiot for even contemplating this? Or is it somehow justified by the irritation that the scratch causes? I haven"t been able to find any place that repairs monitors. Should I just man up or would you buy a new monitor in this situation? Obviously it"s a lot of money having 2 high-end monitors, but I really can"t stand this scratch and if it"s not getting repaired I"ll have to live with it for, well, a really long time, and having 2 1440p monitors would be cool for the symmetry and matching resolutions, and for viewing quality when i watch videos, movies, do the occasional multimedia work, plus my current second monitor, a TN, is kinda weak when it comes to being a second monitor due to the viewing angles being very poor.

I"m really just lost right now. I want a (main) monitor without scratches, and obviously the people who don"t know what it feels like to have a monitor, that you use on a daily basis, that is damaged, don"t think it"s a good idea and tell me to "ignore the scratch", when I can"t.

So what are you guys opinions on my situation? Think it"s worth just getting a new monitor and use my current one as a second monitor because of the scratch and to get dual 1440p? Or am I just being petty?

Mitsubishi Electric company from Japan is well-known the world over for large-screen display panels and industrial-strength LCD monitors. Some of the popular models in use today include the Mitsubishi LDT461V industrial monitor along with the MDT461S and MDT402S LCD monitors.

You may notice that all of these monitors are pretty big in size, ranging from 40-46 ″. To make a comparison, they are similar to the sizes common among plasma televisions, but the technology that powers them is pure LCD.

And like any other LCD monitor manufactured in past two decades, there are two problems that affect even the Mitsubishi monitor– (1) Scratched screen, and (2) Dead backlight.

Since Mitsubishi LCDs are used as industrial-grade displays, the front panel is pretty strong and resistant to scratching. There’s a manufacturing difference between screens used in an industrial setup and one installed in homes.

In the latter case, chances of minor yet visible scratches across the screen are pretty high. The quick fix is to either use a little toothpaste to “fill in” the scratch gaps, or to use a white eraser and vigorously (but gently) rub over the visible scratches.

Make sure it is a brand new one that has never been used before if you’re using an eraser. I’ve tried this scratch repair trick on certain projection TVs and it works fine there.

The second problem is that of backlight repair. The backlight is a thin CCFL tube that lights up the monitor screen. It is powered by an inverter board that converts low-voltage DC input to high-voltage AC output.

A regular backlight bulb lasts anywhere from 3-5 years before it loses part of its brightness. As time progresses, the whole screen goes black and you have no option but to replace the backlight.

Backlight failure is a problem that affects all LCD monitors– including Mitsubishi– though the lifespan will vary based on how you operate it and the quality of in-built electronic components.

The easiest way to repair a LCD backlight is to get a compatible replacement from eBay or the manufacturer’s website. For the most part, you don’t need to buy a new inverter as the existing one can be reused.

The second problem is that of backlight repair. The backlight is a thin CCFL tube that lights up the monitor screen. It is powered by an inverter board that converts low-voltage DC input to high-voltage AC output.

Inevitably, over time the plastic LCD cover on the back of your camera gets scratched, scuffed and generally ends up looking older than the camera really is. Most of the time it doesn’t matter much, you can see the images and menus just fine. But given enough scratches light glare may interfere with seeing the LCD. Or you just may hate that your pride and joy doesn’t look great. We certainly do.

Changing that old LCD cover for a new one is easy to do and inexpensive. We’re going to show you how using a 5D Mk II for an example, but changing it out on other cameras is exactly the same (as is changing out smaller secondary LCD covers if your camera has those). For almost all Canon and Nikon cameras you can find factory replacement covers (and tape, make sure it comes with tape) on eBay or from some camera repair shops that resell parts. You can also buy them direct from Canon or Nikon parts at the moment, but Nikon plans to stop selling all parts soon except to authorized repair centers (who won’t resell parts) so Nikon supplies will probably be drying up. You can sometimes find LCD covers for other brands, but they’re more difficult to come by.

Once you have the new cover, changing won’t take more than 15 minutes. And I should note, all we’re doing is changing the cover, we aren’t doing anything to the actual LCD itself. BUT, if you’re clumsy you could scratch the actual LCD while doing this and that will require an expensive repair. So consider yourself warned.

Use the hairdryer on medium heat to slowly warm up the LCD cover on the camera. You need to get it warm to the touch to soften the adhesive, but you don’t want to cook the camera’s electronics. How warm? Well, like I said warm (not hot) to the touch. I’m not OCD enough to take the temperature of the screen, but it usually takes 2-3 minutes on medium heat.

Once it is warm, find the corner of the LCD cover that seems to have the most room to insert a small knife, screwdriver, etc. Personally, I use a lens cloth under the tools to protect the camera’s finish and find that two pry tools work better than one. The cover is only a mm or so thick and you DON’t want to let the tool move over the LCD screen if it slips. Notice in the picture that both tools are aimed away from the LCD.

Different people recommend different ways to do this. One of the more common is to go ahead and break the cover which makes it easier to pull up. I haven’t been able to summon up the guts to try this method, so I stick with prying up. It may take a couple of times reheating and reprying but once a corner starts to come loose, the screen will pull up very easily.

For most cameras, the replacement tape comes on an LCD size pad with a center protective area –  the double-sided strip of tape is only around the edges. Simply remove the paper over the tape

Make one last check to see if any dust has settled on the LCD, then place the new cover on top of the tape, press down on the edges firmly, and you’re all done. Nice, shiny clean new LCD cover!!!

Strictly for your benefit, my readers, I have demonstrated what happens if you don’t check the underside of the new LCD cover for dust before you apply it. If you notice it (like I did) before you’ve pressed the edges down tightly you can probably pry a corner up and blow it out. If not, well, go back to step 1.

Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.

No, accidental damage is covered for Dell computers or monitors which are covered under the Accidental Damage Service offering for that specific product.

NOTE: Other damages may be considered customer induced if determined by Dell Technical Support, an on-site field engineer, or at the mail-in repair center.

The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.

Internal cracks typically occur due to excessive force on the screen. This can be the result of some object hitting the screen, a drop, attempting to close the lid while an object is on the keypad area, or even holding the laptop by its screen.

Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.

If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.

Dell monitors cannot be repaired by an on-site field engineer or at the mail-in repair center. If you notice any damage to the monitor, you must purchase a new monitor.

Laptop users can strive to make the most of their laptops to maximize stability, longevity, and usability.
