how do you clean an lcd screen made in china

Repair guides can be hard to find. I"ve only seen guides for iMac but the general idea is the same. Remove the LCD assembly from the housing, remove the fixture tapes and side frames from the assembly, lift the panel and clean it. It seems that soft cloth is enough to clean the panels. Be aware of additional dust when wiping the panels and wipe gently, you may scarch the panel in the process if not careful enough. Make sure you seal the assembly well to prevent further dust.

It IS a very difficult repair, the assembly is very heavy, maybe more than 2/3 of the unit"s total weight, and it is a fragile piece of art. Several cables and sensors attach to the back side of the panel. You can easily damage them when lifting the LCD. There are many clips locking the frame. Quite tricky to remove. And at last the LCD driver board is connected to the panel by several ribbon cables. You must not tear any one of them or the entire unit is totaled. In conclusion, very challenging to do so.

Screens can scratch easily, and even paper towels and tissues contain fibers that can do damage. “Your best bet is to use a soft, anti-static microfiber cloth—the kind used to clean eyeglasses and camera lenses—and wipe in a circular motion,” says John Walsh, who cleans more than 250 TVs a year in his role as a CR photographer. (Some TV manufacturers will include a cloth for this purpose.) “Gently wipe the screen with a dry cloth to remove dust and other debris, but don’t press too hard,” he says.

You may also want to wipe down the TV’s cabinet, and make sure dust isn’t clogging the vents that help dissipate heat. If the TV is on a stand and not tethered to the wall, Walsh suggests cleaning with one hand while supporting the TV with the other to prevent the set from tipping over. However, CR strongly recommends anchoring all stand-mounted TVs using anti-tipping straps designed for this purpose.

If there are hard-to-remove stains, you can dampen the cloth slightly with distilled water and gently clean the screen. Don’t spray water directly onto the screen; that could cause a shock or component failure if water seeps into the inner workings of the set.

For the most stubborn stains, you can try using a solution of very mild dish soap highly diluted with water, once again applied to the cloth and not to the TV itself. (As a guideline, Panasonic used to recommend a 100:1 ratio of water to soap.) LCD screens, in particular, are very sensitive to pressure and can scratch easily, so don’t press hard.

Now that the NFL football season has kicked off, you probably want to see all the on-field action as clearly as you can. But TVs, like other electronic items, can attract dust and get marred by blemishes, such as children’s fingerprints.

While you’re at it, also pay attention to the remote controlsfor your TVs, cable boxes, and streaming players. These get handled much more than TVs and harbor pathogens along with plain old grime. We have advice for cleaning both TVs and remotes below.

When it comes to TVs, the current market is dominated by superbright, big-screen LCD (LED) and OLED TVs. However, many of us still have older sets, including plasma TVs, which companies stopped manufacturing in 2014, and even CRTVs—also called tube TVs—which started disappearing around 2008.

If you’re cleaning an older tube TV, you have a bit more flexibility because its screen is made of glass and can be cleaned like other glass items in your household. In this—and only this—instance, it’s okay to use a window cleaner, such as Windex.

More modern TVs are far more sensitive and need to be cleaned carefully to keep the screens from getting scratched or damaged. Plasma TVs also have glass screens, but manufacturers often applied a sensitive anti-glare coating, so they should be treated like an LCD or OLED TV rather than a CRTV set.

In all cases, turn off the TV—or even unplug it—prior to cleaning, says Claudio Ciacci, who heads Consumer Reports’ TV testing program. “In addition to it being safer for the set, it’s usually easier to see dirt or finger smudges when the screen is dark,” he says. “It also gives the TV a chance to cool down.”

If you have any doubts about which type of TV you have, you can always consult the owner’s manual. Most manuals and manufacturer websites have instructions for the best way to clean their sets.

Alcohol and ammonia, found in window cleaners such as Windex, can wreak havoc on your expensive flat-screen TV, so don’t use cleaners that have them. If you decide to use a packaged “screen cleaner”—which you don’t really need (see below)—choose one that doesn’t contain alcohol, ammonia, or acetone. Also, don’t use any cleaners that contain an abrasive that can scratch the screen.

Some of these kits cost $15 to $20 for just a microfiber cloth and a small bottle of cleaning solution, which is probably mostly water. Instead, buy the cloth at an office supply store or online and use distilled water, or a solution of your own making per our advice above. If you opt for a kit, make sure it doesn’t contain harmful chemicals.

Remote controls can get dusty and also harbor a fair number of germs. Think of how many fingers have pressed the buttons on that remote recently and whether all of them were squeaky clean. Then there’s the issue of coughs and sneezes.

Here’s some basic advice about cleaning your remote controls. We also have more details on how to sanitize your remote control if you’re really worried about spreading viruses.

Remove the batteries before you start cleaning. Then start by turning the remote upside down so that the buttons are facing downward, and tap the remote against your palm to dislodge any debris that might have fallen between the buttons. Wipe down the entire remote with a soft cloth that has been sprayed with a tiny bit of alcohol diluted with water. The cloth should be damp, not wet.

To clean in and around the buttons, you can use a cotton swab dampened with the alcohol/water mix. More stubborn debris lodged deeper into the keys can be dislodged with a dry toothbrush or wooden toothpick.

What can be better after a long day’s work than lying down on a sofa watching TV? The television can become our best friend to relieve the pressure from work, relationships, and annoying relatives. LCD TV displays as added “member” of the family also need to be taken care of. For this reason, it is recommended to regularly clean the LCD screen as dust and dirt may affect its performance. What we are trying to say is that if the television is too dirty, you won’t be enjoying your favorite program. Trust me! you do not want that…

How can we clean the LCD Display? This is a concern for many people. Before we find out the answer, we need to know what to avoid. Here, please do not take out your t-shirt and wipe the screen from those beer stains, calm down, and hear me out. Many people would easily make mistakes in solving this problem even without consciousness. So let’s take a look at some wrong cleaning methods first: Wiping the LCD Screen directly with the palm or fingers

You should know that LCD should not be touched. When rubbing with the palm or fingers, it is difficult to use the right amount of force. If the force is too strong, it may cause permanent damage to the liquid crystal molecules, which translate into watching at a multicolor liquid stain on your TV instead of your favorite show. Wipe the LCD screen with a rough towel

Someone may directly clean the LCD display with the towel used to wipe the table at home. However, this is a wrong behavior as you can scratch the surface or get the screen even dirtier. Do not also use paper towels, toilet paper, or old T-shirts. These materials are abrasive and leave a lot of residues.

Now that we know what we should not do, let us move with the proper cleaning methods. First of all, let us briefly explain the LCD TV display structure. The LCD panel is mainly composed of two sodium-free glass sandwiched by a polarizer, a liquid crystal layer, and a color filter. Feeling confused? check here our article about LCD TVdisplays.

Moving on to the cleaning. Well, the first thing you should do is to turn off your television. I know it seems obvious to say, but many people do not follow this step. After that, you have two main choices: standard or creative method:

The first being the standard option, is the most formal and troublesome. Stand up and go out buying the special LCD cleaner and microfiber cloth to clean the LCD screen. If you are too lazy, you can order it online. Although this method is effective, it implies that you need to buy the cleaning agent and my friend, depending on how regularly you clean, it can be expensive. Once bought the products, apply the cleaning agent to the cloth and gently wipe the entire surface of the LCD TV display, removing any visible traces of dirt and dust.

If you thought it was too easy after hearing the standard option, or those nasty stains are still there, we have the solution for you. Here we share the “creative” method.

Prepare a liquid solution using equal amounts of vinegar and water. Vinegar is a natural and safe detergent and is much cheaper than the products on the market, specially designed for cleaning televisions.

Dampen the microfiber cloth in the vinegar and water solution and then wipe your TV screen softly. If necessary, apply gentle pressure and a circular motion to the spots where you notice stubborn stains. Keep in mind not to spray the vinegar solution directly on the TV screen, as you could damage it irreparably.

Following, use a second microfiber cloth to dry the TV screen. Pay attention not to allow the screen to air dry. Otherwise, annoying halos may remain and influence image quality.

Finally, wash the plastic frame of the TV. If the frame also requires a more intensive cleaning, use some paper towels after wetting it in the vinegar and water solution. Use paper towels to dry it completely.
