What if my TV screen is dirty?
When the TV screen is dirty, you can wipe it gently with a soft, lint-free cloth, do not touch it with water. Because even in a power-off state, components such as backlights (such as CFL inverters) may still carry a high voltage of about 1000V, which can cause serious personal injury.
On the other hand, the LCD TV screen is coated with a special coating, do not use detergent or alcohol to clean the screen when cleaning, so as to avoid artificial damage to the components. Plasma TV is the same principle, so as not to leave spots or water marks on the glass and special adhesive layer on the surface of plasma TV. Furthermore, water entering the LCD can cause a short circuit.
Don’t look at the size of flat-screen TVs, they weigh as much as a junior high school student, LCD screens and plasma screens are quite fragile, even LG’s hard screens are no exception, so avoid strong shocks and vibrations , do not apply pressure to the screen surface.
For the screen-specific flat-panel TV cleaning cloth, wipe it directly without adding cleaning solution. Or use a special cleaning solution, spray it on a dry soft towel and wipe it gently, never spray it directly on the screen. After cleaning, let it stand for 30 minutes, and then energize to remove moisture. If moisture gets into the LCD, put it in a warmer place immediately to allow the moisture and organic compounds in it to evaporate.
For the fuselage, you can use a wet towel, but be careful not to let water drop into the cooling holes to avoid short circuits.
How to clean the smart TV screen?
Do not clean with water, because liquids can easily drip into the LCD TV, which will cause a short circuit of the device. Usually alcohol can dissolve some dirt that is not easy to wipe off. You can use alcohol to clean the monitor case, but be sure not to use alcohol to clean the LCD screen, because wiping the monitor screen with alcohol will dissolve the special coating on the surface of the LCD screen. The display effect is adversely affected.
When cleaning the dirt on the surface of the LCD screen, you can spray an appropriate amount of non-ionized water with a special wiper for LCD, and then wipe it again, so that the dirt will not be traced and the LCD screen will not be scratched.
The surface of the LCD screen looks like a solid black screen. In fact, manufacturers will add a special coating to this screen. The main function of this special coating is to prevent users from being reflective and glare from other light sources during use, and to enhance the color contrast effect of the LCD screen itself. However, because the coating materials used by various manufacturers are not the same, of course, its durability will also vary. Therefore, users must not use any alkaline solution or chemical solution to wipe the screen surface when cleaning.
The smudges on the LCD panel are roughly divided into two types, one is the dust in the air that has accumulated over time, and the other is the fingerprints and oil stains left by the user inadvertently.
There are three common misunderstandings when consumers clean LCD screens:
Misunderstanding 1: Use a soft cloth or paper towel to wipe the LCD screen
Never use ordinary soft cloths (such as glasses cloth) or paper towels to wipe the LCD screen. For soft LCD screens, their surface is still too rough, and it is easy to scratch the delicate LCD screen.
Myth 2: Use clean water to clean the LCD screen
When cleaning with water, the liquid can easily drip into the LCD TV, which will cause a short circuit in the equipment circuit and burn out the expensive electronic equipment . And for fingerprints and oil stains, water is still powerless.
Myth 3: Use alcohol and other chemical solvents to clean the LCD screen
In general, alcohol is a common organic solvent that can dissolve some dirt that is not easy to wipe off. If it’s just used to clean the monitor case, it doesn’t have any ill effects. But be sure not to use alcohol to clean the LCD screen, because the current LCD screen is coated with a special coating on the screen to make the screen have a better display effect. Once the display screen is wiped with alcohol, this special layer will be dissolved. The coating will adversely affect the display effect. It is even more inadvisable to use chemical solvents. This chemical preparation is a devastating blow to the “arrogant” LCD panel.
What is the best way to wipe the LCD screen?
If your screen is accidentally stained with juice, saliva or coffee, etc. For stains that are not easy to clean, you can use a special LCD wiper to spray an appropriate amount of non-ionized water to make the wiper feel slightly damp, and then wipe it again, you can make the stains disappear without scratching your LCD screen. Because the special liquid crystal wiping cloth is made of special fibers, it has a much better wiping effect than the general high-end glasses cloth, and it is soft and will not scratch the screen, and also has the unique function of dissipating static electricity.
With the special cleaning cloth for LCD, I believe that no matter how dirty the LCD TV screen is in the future, there is no need to be afraid. But here I still want to remind you: don’t wipe your LCD TV screen every day, this is also a lot of damage to the LCD screen.
Other issues to be aware of
While flat-screen TVs have an expiration date, they are often still in service for those who don’t use them properly Inside, there are many problems. So if you want to extend the life of your own TV, you must pay attention to some small details when you use it normally.
First of all, long-term use of plasma TVs may cause local burns on the screen. When the plasma screen is fixed at the same image position for a long time, then the light emission state of each plasma chamber is constant at this time, which will make the whole picture appear like a shadow. Therefore, you must not let the plasma TV freeze on the same picture for a long time. This damage is sometimes irreparable and is the biggest damage to the plasma TV.
Secondly, although the resolution of the flat-panel TV can be adjusted by the user, the flat-panel TV can achieve the best imaging effect under the recommended display resolution, which is also a kind of protection for the screen. Therefore, try to choose the resolution recommended by the flat-screen TV itself.
Third, the HDMI interface has now become the standard configuration of LCD TVs. One of its advantages is that it is easy to use. Only one HDMI cable is needed to transmit all audio and video, and the interface is designed to be very easy to pull out. Plug, can be easily plugged in and unplugged. But this brings a problem: Since the HDMI interface does not support hot swapping, if you plug or unplug it directly in the power-on state, it is easy to burn the chip of the HDMI interface. Therefore, when you unplug and plug the HDMI cable, please do not hot-plug, and only after the TV and HD player are turned off can they be unplugged.
Fourth, when the LCD TV needs to be cleaned or breaks down, consumers should not disassemble it by themselves. Because, even with the switch off, the CFL inverter in the TV’s backlighting assembly can still carry a high voltage of about 1000 volts, which can cause serious personal injury, and even if there is no electric shock, wrong operation is possible As a result, the display screen cannot work temporarily or even permanently. And once you disassemble the LCD TV by yourself, you may no longer be able to enjoy after-sales service.
Environment: reject high temperature, humidity and electromagnetic interference
Flat-panel TVs have stricter environmental requirements than CRT TVs.
The first is temperature. Taking LCD TV as an example, it is normal for LCD TVs in the Chinese market to have a working temperature in the range of 0 to 45°C, depending on the specific brand and model. Therefore, home users must ensure the indoor temperature if they want to watch TV normally, otherwise problems such as discoloration and color cast will occur. And don’t let high-temperature heat sources such as electric stoves too close to the TV.
The second is light. Flat-screen TVs should not be placed in direct sunlight.
The third is the interference of electromagnetic signals. Although the flat-screen TV is hung on the wall, it should be kept away from the surrounding strong electricity and strong electromagnetic field objects, such as induction cookers, microwave ovens, etc., especially those that can be moved at will such as radios. keep distance.
