how to clean ipad lcd screen factory

I used to have this same problem, but not any more. I came up with the perfect method of cleaning the LCD panel. First of all, I had no idea that alcohol would damage the LCD. I normally use 90% Isopropyl Alcohol for cleaning everything on the smartphones and tablets that I repair. I might change that back to a pre-mixed 50% solution, but the 50% does not remove grease as well. I honestly don"t think a 1-time cleaning using the 90% will cause a problem. I could believe that continued cleaning with the alcohol could cause damage, however.

What works best for me is to follow this 3-step procedure. And take note, scrubbing an LCD with a back-and-forth motion will only get you frustrated, just as the previous poster had mentioned. I"ve been there, rubbing on an LCD for upwards of an hour, only ending with the same grease smudges that I started with. Well anyway, here"s my 3-step process:

1. Using a micro fiber or dust-free cloth, or even a soft toilet paper, put a liberal amount of the alcohol on your cleaning cloth and use "flood-strokes" on the LCD in one direction ONLY. Wipe down the LCD in as few strokes as possible, as wide of a stroke as you can with your cleaning cloth or TP. You should use enough alcohol that it leaves a wet film on the LCD.

2. Blow dry (with your mouth or a heat gun on low) the alcohol. It will disappear very quickly. If you see any spots, repeat step 1, and then do this again. You will see residue on the screen, but it should be very uniform, and in the direction that your flood strokes were in step 1. If you do this right, you may not see any streaks at all.

3. Using your hot breath (hopefully your breath isn"t so bad that you melt the LCD, so be careful here), steam up the surface of the LCD and use the lint-free cloth to wipe the steam. This will get rid of all the residue left behind by the alcohol. It"s okay to wipe in a back-and-forth motion when using the hot-steamy-breath application of moisture. In only 5 minutes, your LCD should be completely free of streaks, grease, and dirt. Blow away any excess lint, and get the glass digitizer put on it as quickly as you can before your LCD attracts dust out of the air.

One thing I would also recommend is that you have a good filter in your HVAC system. Some people I know of actually use a hood that forces air through a filter, and into the hood. This way, you don"t have any ambient air coming into contact with your LCD, because you are operating in a positive-pressure environment with incoming air that is filtered, and thus exhausting into the room after leaving the hood.

I will be writing a post on this and possibly doing a video for my blog site, which is the Carlton Zone Blog. Check the site soon. I would be glad to post videos and advice for repairs, because I do a lot of this.

When it comes to cleaning, flat-screen TVs and LCD screens require special care and a gentle touch. With the wrong technique, you can easily scratch the screen or damage the surface"s antiglare coating. Even rubbing too hard can cause pixels (the tiny dots that compose images on computer monitors and TV screens) to burn out and stop working permanently. Most household cleaning products are too harsh to use on electronic devices with LCD or OLED screens, so choose your TV cleaning strategy carefully. These tips on how to clean a TV screen will help protect your device while ridding it of dust, smudges, fingerprints, and streaks.

Before you begin cleaning a TV or LCD monitor screen, check the manufacturer"s manual for cleaning instructions. If a computer or electronic wipe is recommended, purchase a container for quick cleanups. Note that using a cleaning product or method not recommended by the manufacturer will likely void a product"s warranty. It"s also important to avoid spraying liquid on the screen when cleaning a TV. Liquids can drip into the frame, get wicked inside the screen, and cause permanent damage.

If streaks or stains remain, wet a microfiber cloth with distilled water and wring the cloth until it"s almost dry. With very little pressure, wipe the cloth across the screen in broad motions, working from the top of the screen to the bottom. If smudges persist, dampen a new microfiber cloth with 50-50 water and vinegar solution, wringing it tightly to keep it slightly damp, and wipe.

To avoid damage to your TV while cleaning, only use gentle products. Never wipe the screen with paper towels, abrasive sponges, or coarsely woven rags, which can cause scratches. Instead, use high-quality, finely woven microfiber cloths to clean TV screens, recommends cleaning expert Leslie Reichert.

You should also avoid cleaning products that contain alcohol or ammonia. These types of cleaners can remove antiglare coatings and cause images to become cloudy or distorted. A simple swipe with a microfiber cloth ($9 for 5, Amazon) is typically all that"s needed to remove dust and other debris from the screen"s surface. When more than a light dusting is required, however, use the guidelines below for the best way to clean a TV.

Practice preventative measures so you won"t have to clean TV screens often. Keep food, drinks, and kids away from TV and computer screens to eradicate risks of messy splatters and fingerprint smudges. During your weekly house cleaning, lightly dust the screens with a microfiber cloth to prevent dust buildup.

Follow the steps below to safely clean your flat screen monitor, TV, laptop screen, or other device in just a few minutes. This information applies to televisions from manufacturers including LG, Samsung, Panasonic, Sony, and Vizio.

Turn off the device. If the screen is dark, it will be easier to see the areas that are dirty or oily. Turning the device off also prevents you from accidentally pushing buttons you don"t actually want to push, which happens a lot when cleaning touchscreen devices like tablets, iPads, etc.

If the dry cloth did not completely remove the dirt or oil, do not press harder in an attempt to scrub it off. Pushing directly on the screen can often cause pixels to burn out, especially on laptop displays, desktop monitors, and LCD/LED TV screens.

If necessary, dampen the cloth with distilled water or with an equal ratio of distilled water to white vinegar. Many companies also sell small spray bottles of special cleaner for flat screens.

Avoid using paper towels, toilet paper, tissue paper, rags, or something like your shirt to wipe the screen. These non-ultrasoft materials can scratch the display.

Avoid cleaning products that contain ammonia (like Windex®), ethyl alcohol (Everclear® or other strong drinking alcohol), toluene (paint solvents), as well as acetone or ethyl acetate (one or the other is often used in nail polish remover).

These chemicals can react with the materials that the flat screen is made of or coated with, which could permanently discolor the screen or cause other kinds of damage.

Never spray liquid directly onto the screen. It could leak into the device and cause damage. Be sure to always put the cleaning solution directly onto the cloth and then wipe from there.

These same cleaning "rules" apply no matter if your TV is 8K, 4K, or 1080p (HD). Those differences don"t mean the display is necessarily made out of anything different, requiring different cleaning, it"s just a measure of how many pixels per inch they shoved in the same space.

If you"re cleaning your TV because it appears dirty, but then find that the screen is actually physically damaged, you might be ready for a new HDTV. See our Best TVs to Buy list for our top suggestions, or this Best Cheap TVs list for some budget-friendly HDTVs.

Plasma TVs are glass, as are many touchscreens, but often also have very sensitive anti-glare coatings applied. Take the same special care with those types of displays.

Today, many of us rely on our smartphones to communicate, work, and play. Therefore, it can be quite alarming when they begin to act strangely – especially if you can’t get your phone to turn on at all.

One of the most concerning issues to plague smartphone users is a black screen, often referred to as the “black screen of death.” However, despite the harsh name, this issue can be remedied in several ways.

To fix a black screen on an iPhone or Android, the first (and easiest) step is to do a hard reset. This basically entails rebooting the phone’s software. A hard reset can be performed right on your phone, although the process differs depending on what type of device you own.

If you’re still staring at a blank screen, it’s possible that the cable connecting the logic board to the LCD screen has become disconnected. This can occur if you accidentally drop your phone a few times. In order to regain your screen’s functionality, the cable will need to be plugged back in.

If you want to repair a broken iPhone or Android this way, it’s best to seek help from a professional. While you may find DIY instructions online, you could risk causing irreparable damage to your device if you don’t know what you’re doing. So, if you suspect that your phone’s LCD cable is disconnected, search for a place in Las Vegas that fixes phones.

When your phone screen goes black randomly, it may be an indication that something is wrong with your operating system. In that case, a factory reset is often beneficial. During a factory reset, your device’s data and settings are completely wiped, returning the phone to its original state (i.e., the state it was in when you first purchased it).

Not sure how to do a factory reset on an iPhone or Android? The process is more involved than that of a hard reset but can still be done with moderate ease.

Keep in mind that this process takes longer than a simple hard reset – you may have to wait several minutes for your phone to restart. Once the process is complete, check to make sure the device has been restored to its factory settings. If you’re presented with the iOS Setup Assistant upon startup, you’ll know the reset was successful. From there, you can choose to restore your backed-up data.

Sometimes a power button can get stuck due to trapped gunk, debris, or sticky food. You can try to dislodge debris by pressing the button rapidly several times. In most cases, the most effective method for sticky buttons is applying a Q-tip with rubbing alcohol. Swab the area around the button to loosen up and extract dirt, dust, or whatever might be trapped in there. In some instances, you may have a broken button that will need to be repaired.

Your phone may not be charging properly if the charging port is blocked off due to grit or debris. Simply blowing on the port a few times can help. For a deeper clean, you can try gently scraping with a toothpick or using a cotton ball (or Q-tip) with rubbing alcohol. Some people recommend trying a low setting with a vacuum to extract dirt, but that can easily damage parts. Blowing out dirt with compressed air is a safer alternative.

Software issues with apps can sometimes cause a phone to act unpredictably. If you are noticing certain apps are crashing frequently, you should update them immediately. You should also consider deleting buggy apps for security and the health of your phone. If an app has crashed on your Android, you can force stop it through settings > apps & notifications -> see all apps -> force stop.

Apple’s iPad remains one of the best tablets on the market. Apple has sold well over 350 million worldwide, and there are currently a number of different models to choose from. While these tablets are certainly well-engineered pieces of digital machinery, they are not immune to a few snags and glitches. We"ve taken a look at some of the most prevalent iPad problems in an attempt to find workable solutions for them. Sometimes it will take more than a simple reset to get your iPad back in working order.

It can be frustrating if a pixel isn’t working on your iPad. You’ll first notice this as an unresponsive dot on the display that doesn’t change, or stays black no matter what happens. Sometimes there may be more than one pixel like this.

If the pixel still lights up but is simply stuck or never goes to the right color, you can try manually fixing it yourself. Wrap your thumb in a clean cloth and apply gentle, firm pressure to the area of the display with the pixel, slowly moving your thumb as you do so. Sometimes this can help fix any issues the panel is experiencing.

Flashing bright, changing colors can also help reset a pixel. You can plenty of Pixel Fix videos on YouTube to run at full screen to help with this, or even find an app that does the same thing.

If the pixel is permanently dark no matter what you do, it’s dead. You cannot fix a dead pixel. If it’s a minor issue and not distracting, you can leave it. But it’s a good idea to take your iPad into an Apple Store and ask about a display replacement.

Eager to get the latest iOS/iPadOS updates and all the new features offered? You may discover that your iPad is obstinately refusing to download the update, even if it says it will or if it was scheduled to update at a specific time. Fortunately, this is usually due to not meeting specific requirements needed to update, not a permanent flaw on your iPad.

Double check to make sure your iPad is compatible with the latest versions of iPadOS. Check out our list of iPadOS 15 compatible devices and iPadOS 16 compatible devices.

Make sure you are not using a cellular data connection for your internet. The iPad will not start such a big download when on a data connection to avoid using up cell data.

You may find from time to time that your iPad screen freezes and remains unresponsive to your touch. It’s a common complaint at Apple’s support forum. The most likely culprit is a specific app, but it’s not always easy to identify which one. If it happens repeatedly, take note of what you have running and try uninstalling it to see if that solves the problem permanently. Whatever the cause, your immediate solutions to a frozen iPad screen are the same.

Try restarting your device first by pressing and holding the Power button until you see “slide to power off” on the screen, and then slide to power off. Press and hold the same button to turn it back on. You’ll know it worked when you see the Apple logo.

If the screen isn’t responding, you might need to force restart the device in which case you should press and hold the Power button and the Home button at the same time for around 10 seconds. You’ll know it worked when the Apple logo appears. For newer iPads without the Home button, press and quickly release the Volume Up button, press and quickly release the Volume Down button, and then press and hold the Power button until the device restarts.

If it stubbornly refuses to react to a restart or reset, then you’ll need to try a restore. Plug it into your computer using the cable provided. Load up iTunes on the computer, select your iPad, choose the Summary tab, and hit the Restore iPad button. This will erase your content, so you may prefer to choose Restore Backup on the Summary tab. Bear in mind that you’ll lose anything you haven’t backed up.

It’s a nightmare with any electronic device when it refuses to turn on at all. Don’t assume the worst, though, it may prove easy to revive. This is another common post in the Apple support forum.

Try holding down the Power button and the Home button together until you see the Apple logo. For newer iPads without the Home button, press and quickly release the Volume up button, press and quickly release the Volume down button, and then press and hold the Power button until the device restarts.

Maybe the battery is just empty. Plug the iPad into the wall charger using the original cable and charger that came in the box and wait an hour before trying the first step again.

If your iPad turns on but gets stuck during startup, then plug it into your computer with iTunes running and repeat step one, except this time, don"t let go of the buttons when you see the Apple logo, keep holding them until you see the recovery mode screen. You should get the option to Restore or Update. Choose Update and it will try to reinstall iOS without wiping your data.

Some people have reported issues with plugging the iPad into the computer and booting up iTunes only to find that the iPad isn’t there. If iTunes or Finder isn’t recognizing your iPad then you can try a few things to solve the problem.

Check the battery icon on the iPad when you plug it into your computer. If it has a lightning bolt on it to denote charging or it says Not charging next to it then you know the port and the cable are working and you can move to the next solution. If it doesn’t, then try another port. If that doesn’t work, then try another cable.

(If you are running MacOS Catalina you can skip this as you"ll be using Finder to interface with your iPad.) Make sure you have the latest version of iTunes. If it’s on a PC then go to Help and then select Check for updates. If it’s on a Mac then hit the iTunes tab and select Check for updates. If you have the latest version or updating makes no difference, try the next solution.

Turn the iPad off. Turn the computer off. Turn them both back on again and plug the iPad back in. If you see a Trust this computer alert, unlock your device and tap Trust.

If you find that your iPad won’t charge when you plug it into a power adapter, there are a couple of possible reasons. If it doesn’t charge when you plug it into the computer, it may just be the port you are using, try the power adapter instead. You can see whether the USB port on your computer is charging it or not by looking at the battery icon on the iPad. If it is charging, you’ll see the lightning symbol; if not, it will say Not charging next to it. Some computer ports can’t provide enough juice to charge the iPad, and it will always charge more slowly via the computer, even if it does work.

You want to check if it’s the cable or power adapter itself so, if possible, try the cable and power adapter with another compatible device, or try a different power adapter and cable.

If the cable or power adapter is not the problem and nothing else has worked, then there could be a fault with the iPad and you’ll need to contact Apple, contact the retailer where you bought it, go into an Apple Store, or take it to a third party repair shop as the culprit could be a damaged battery, or a damaged charge port, both of which are repairable.

A lot of people have trouble connecting to Wi-Fi networks with their iPads. Before you start serious troubleshooting, you should check Settings > Wi-Fi on the iPad and make sure that it is turned on. It’s also worth making sure that Wi-Fi is accessible on another device.

There’s a reason IT departments the world over tell everyone to turn a device off and on again as a first troubleshooting step — because it so often works. Try turning off your iPad and router and then turn them both on again and wait a few seconds before trying to reconnect.

Try telling the iPad to forget the network in Settings by tapping the network name and selecting forget. Turn the iPad off and on again and then reconnect to the network and re-enter the details as necessary. You can also try Settings > General > Reset > Reset network settings.

Make sure you have the latest iOS software by going to Settings > General > Software update. You should plug your iPad into the power adapter before updating. Older iPads can be updated via iTunes on the Summary tab via the Check for update option.

If your iPad still won’t connect then it’s worth checking with your ISP for help or advice. The problem could be related to your specific router. You might want to update the firmware or change the channel.

If nothing so far has worked, then you may consider trying to connect to a different Wi-Fi network with your iPad just to test if it works. If not, then it"s time to contact Apple for further help.

If you find that your iPad is not its usual zippy self and you are experiencing some lag when you navigate, you can try a couple of fixes. You may just have too many things running.

Double-tap the Home button and swipe up on each open app or game to close it. If you have a newer iPad without the Home button, then swipe up from the bottom of the Home screen and pause slightly in the middle of the screen to open the recently used apps list.

You could also just reset the iPad by holding down the Power button and the Home button simultaneously for 10 seconds. For newer iPads without the Home button, press and quickly release the Volume up button, press and quickly release the Volume down button, and then press and hold the Power button until the device restarts.

You really need at least 2GB of free space for smooth operation, so take a look in Settings > General > iPad storage and check. You may need to delete some files or uninstall some apps. Some apps take up more and more space over time, so it can even be worth uninstalling and then reinstalling an app to clear it. You may also consider going to Settings > Safari and tapping Clear history and Website data, then Clear history and Data to clear out your cache, but this will also log you out of websites you"ve signed into.

As a last resort, you might try a factory reset. This will wipe everything though, so make sure you back up first. If you do a factory reset, test the iPad without restoring a backup just to see if it runs any better. If you subsequently restore a backup and it slows down again, then you"ll know the issue is with something in the backup.

Quite a few iPad owners have been complaining about cellular data connections dropping frequently. Obviously, this will be seriously influenced by how good the coverage is in your area. If you have good coverage on the same network with your phone, but the iPad is struggling, you could try a couple of things. First, check in Settings > General > Cellular and make sure it’s on. You could also try a restart. If it continues to be a problem, go through the steps below.

A lot of iPad owners suffer from random crashes where an app spontaneously closes or the iPad suddenly restarts. You might find that this is a bigger issue on older iPads. You can try a few different things to alleviate the problem. It is quite likely to be related to specific apps, so take note of what you were doing when it crashes and see if a pattern emerges over time.

Press and hold the Power button and then slide to power off. Press and hold the button to turn it on again. You could also reset by pressing and holding the Power button and the Home button at the same time for 10 seconds. For newer iPads without Home buttons, press and quickly release the Volume up button, press and quickly release the Volume down button, and then press and hold the Power button until the device restarts. Neither of these solutions is liable to affect a permanent fix, but it may offer some relief.

Connect to Wi-Fi and go to Settings > General > Software update to ensure that your iPad has the latest software. If there’s an update available then download it and install it.

If your crashes are occurring in Safari specifically then try going to Settings > Safari and tap Clear history and website data, then Clear history and data. Note this will log you out of websites that you"re logged into.

If none of the above has worked for you then try contacting Apple. If you’re able to reproduce the crash and you can take it into an Apple Store to show them, then you will be able to get some help.

When everything is running as it usually should, your iPad should take about three hours to recharge. If you own an older model, it still would only take about four hours, at a maximum. That said, many users report that it takes much longer for their iPad to recharge fully. We have a couple of tips to try and speed up the charging process.

Make sure your iPad is updated. Infamously, iPadOS 13 caused these types of battery charging issues for many users. If it"s an issue with iPadOS, you can"t do much except live with it until Apple improves the software and releases a new version.

Check your ports and connectors. Look for any signs of damage, grime that"s blocking ports, or anything else that may be interrupting the connection. If you aren"t sure, try to find another compatible charging cable and switch it out to see if this makes a difference. Do not use an off-brand cable or charger to charge your iPad! If you are using one, stop right away and switch to a version straight from Apple.

Make sure your iPad isn"t trying to do a lot when you are charging it. Disconnect from Wi-Fi and Bluetooth or put it into Airplane mode first. Don"t use your iPad when it"s charging, and see how much this helps.

Always remember to make sure that your iPad isn"t put in a particularly hot or cold place. This can damage the battery and cause long-term problems that can"t really be fixed without a full replacement.

We completely understand how frustrating this issue can be, mainly because you likely bought the Pencil to pair specifically with your iPad. We have several solutions to try out to get the two working together again.

Make sure you have the right Apple Pencil and iPad. Compatibility issues do exist. We have a full Apple Pencil compatibility guide, and certain Apple Pencil and iPad combinations simply won"t work. Also, if you have an iPad Air 2 or earlier model, the Pencil won"t be able to work with your screen at all, although some third-party stylus models could work for you. We know, it"s confusing. But it"s important to find out what Pencil and iPad model you have to see if they can work together.

Restart your iPad and try again. When you restart, take a look at Settings and Bluetooth to make sure your Bluetooth is turned on. If you already see the Pencil as a recognized device in the Bluetooth settings, then select the information icon, and choose Forget this Device. Then try reconnecting.

A bootloop is when your device gets stuck in a cycle of turning off and turning back on; The iPad continues repeating that over and over again on a seemingly endless loop. We’ve found that these frustrating cycles tend to result from a bug in whatever app you were last trying to use. That said, there could also be a couple of other factors causing the bootloop. We have several recommendations to try out to stop the looping before you take your iPad to the Apple Store for help.

* Wait for an update. Unfortunately, bootloops are often caused by bugs in specific apps or the iPad’s current operating system. In that situation, you just need to wait for an app or OS update to be released. A recent example of this happened in June 2020, when a version of iPad iOS caused iPads to bootloop unexpectedly while working, usually around a minute or so after starting up. Apple doesn’t waste a second when it comes to releasing patches for these problems. Just keep an eye out for new updates.

* Force a manual restart, or “soft reset,” and see if it solve the problem. A manual reset is a powerful troubleshooting tool. To start the reboot, hold the Power and Home buttons down for about 10 seconds simultaneously. You don’t have to count it down; you’ll see when the reboot has started because the Apple logo will appear on the screen. Some newer iPads don’t have a Home button. For those devices, press and quickly release the Volume up button, press and quickly release the Volume down button, and then press and hold the Power button until the device restarts. If this doesn’t work, you may need to force a factory reset, unfortunately. Before resetting anything, though, may sure you back up all of your important data.

* Go into recovery mode. This feature prevents bootloops and opens the door for your iPad to fully update if your device is stuck in an infinite bootloop. Apple has a full guide, but to explain it briefly — connect your iPad to a computer; then press and release the Volume up button, the Volume down button, the Top button, and then hold the Top button as your iPad restarts. If this is completed correctly, your iPad will reboot into recovery mode. If your device has a Home button, hold the Home and Top buttons simultaneously. Continue holding them until you see that recovery screen.

Many Apple iPads can have the digitizer easily changed without the need for special laminating machines. However, some of the high-end devices contain bonded screens where the digitizer is laminated to the display. When the screen breaks on these models (including the iPad Air 2, iPad Mini 4 and iPad Pro series) you would normally have to swap out the complete display. The good news is that you can now have these broken iPad LCDs refurbished at a price that makes it well worth your time.

As long as the LCD itself is still functioning, you can send us the display and we are able to refurbish it by laminating a new digitizer onto your LCD. Unlike our iPhone refurbishing service, we don’t require the touch to be working in order to refurbish these iPads. This is because our process involves laminating a new touchscreen and only using as close to original parts as possible.

For us to be able to refurbish your iPad screens, the LCD itself needs to be fully working (only the touch can be defective). If there is any sign of LCD bleed, waves on the backlight, yellow bruising on the screen or pressure marks from the cracked glass then we would normally reject that screen.

After the form has been completed a copy will be emailed to you. When you receive this please print off a copy and include it inside your the package alongside the screens.

It is important you package the screens correctly to ensure they don’t get damaged in the post. (See our “How to Pack Screens” guide for full details). When the glass is already cracked, it makes the underlying LCD panel weaker as there is no support from the glass to protect it. Any flexing of the screen can risk it getting broken, and rejected for refurbishment.

When your package arrives with us we check every screen carefully to make sure there are no defects. We’re looking for backlight damage, pressure marks on the screen, or even a badly dented backlight- all of which may mean an LCD is rejected. However, we always send back rejected screens with an order so if you’re not sure whether we would accept a particular LCD or not, then you’re more than welcome to send it to us to check.

When a screen enters the refurbishment process, we generally cut the broken digitizer off using molybdenum cutting wire and a hot plate. Some other refurbishers use a freezer to separate these screens, but this is risky as the iPad’s LCD panel uses a backlight which can be easily damaged this way. By using the hotplate instead, we can preserve the original backlight.

Once the broken digitizer has been removed, we then clean up the iPad LCD and replace the polarizer as necessary. Next, the LCD would be fitted into the mould for our laminating machine, ready to get the new digitizer laminated. We only use the highest quality digitizers, and they are as close to original as possible. The new digitizer contains the rainbow tint around the camera hole and an oleophobic (grease-resistant) coating.

Finally, once all the bubbles have been removed, the newly refurbished iPad LCD moves to the final stages where we solder a new sensor (if necessary), and fully test the LCD for any dust, imperfections or touch issues. Once everything has been checked we fit our warranty sticker and package it in a bubble bag ready to be shipped back to you.

As with any electronic item, televisions attract dust and are magnets for smudges and children"s fingerprints. Luckily, learning how to clean a flat-screen TV is fairly straightforward, requiring very little time and few materials. Regardless of whether you have an LCD or a plasma TV, all flat-screen TVs are made out of thin, flexible materials and should be treated very gently. They have extremely sensitive components, and using chemical cleaners may lead to a broken or blank screen (so skip the window cleaning spray!). Even ordinary kitchen towels or paper towels can cause marks and scratches on the screen. Here"s the right way to clean a flat-screen TV and prevent costly damage.

Turn Off the TV.Shutting off your monitor will not only help you see where dirt and dust have collected, but it will also give your screen time to cool down. A warm or hot screen will be harder to clean, increasing the chances that you"ll accidentally damage it if you scrub too forcefully.

Consult the Owner"s Manual (seriously!).If you take a quick survey of the different cleaning recommendations from various flat-screen TV manufacturers, you"ll quickly discover that many of the directions conflict with each other. When in doubt, check your owner"s manual or look online at the manufacturer"s website for instructions on how to clean your flat-screen TV. This cautionary step will prevent you from doing something the manual warns against, thus voiding your warranty.

Wipe Only With a Soft Cloth.Gently wiping the screen with a dry, soft cloth may be the only universally agreed upon method for cleaning a flat-screen TV. While this will likely take care of any surface lint, it may not be enough to remove oil or dirt. Be warned, an attempt to scrub the screen by using any amount of pressure may only cause the liquid crystals inside to misalign or burn out.

Then, Try a Damp Cloth.Unless your owner"s manual specifically prohibits it, carefully wipe the screen with a damp, lint-free cloth. When using water, be sure to spray onto the cleaning towel rather than directly onto the screen. This will give you more control over where the water is going and how much is being used.
