How to hang and install Skyworth LCD TV 20L98TV
1. First of all, you must understand the walls of your home
The basic walls of a room are generally divided into two types: load-bearing walls that support the entire building and lightweight brick walls used for partitions. Small-sized LCD TVs and indoor air-conditioning units can be safely hung on lightweight brick walls. If you want to hang a flat-screen TV on a TV background wall made of gypsum board, you must add solid wood inside. And the 50-inch Large-screen flat-screen TVs, especially plasma TVs, are best hung on load-bearing walls for safety. Of course, during decoration, you should also try to clearly plan the equipment that needs to be hung on the wall to avoid unnecessary trouble after the decoration is completed.
A room can limit the range of activities, but it cannot limit the endless imagination of life. If you are still thinking about how to put more equipment into a limited range, you might as well think about it from another angle, why it is necessary to put every device into a limited range. Everything is "placed" at home? If you hang as many things as possible on the wall to experience the unrestrained life without worrying about bumps and bumps, I believe everyone will not refuse. Although technology is people-oriented , but the feelings and meanings of life are different for everyone, and we need to discover and change ourselves from time to time.
Wall bearing capacity: The bearing capacity of the installed wall should be guaranteed to be no less than the actual load of the TV. Four times the weight, the TV should not tip over when it is tilted 10 degrees before and after installation. It is best to choose a solid wall instead of a hollow or shoddy engineering wall, otherwise the TV will easily fall off.
2. Installation environment: When choosing to install a wall-mounted TV, you have to pay attention to the surrounding environment of the TV. If the environment is too humid, it will affect the service life and safety of the TV. Serious signal interference will cause signal interference and affect the viewing effect.
Three . Installation location: When installing a flat-panel TV, the viewing distance should be at least 3-5 times the diagonal distance of the display screen. The installation height should be such that the user is sitting on a stool or sofa and looking directly at the center of the TV (or slightly below). Generally, the TV can be The center point is about 1.3m from the ground.
4. Selection of wall-mounted brackets: It is very important to choose a suitable wall-mounted bracket, so that the design of the wall-mounted bracket must go through strict calculations and multiple tests. , the strength and durability are relatively guaranteed.
5. Installation precautions:
1. Accurately locate the installation position of the flat-panel TV on the installation surface, and the positioning accuracy must be ensured , fix the mounting surface hanger part.
2. For general flat-panel TVs, the heat dissipation grille is usually designed on the back or side back, so the back of the TV and the upper, lower, left, and right sides need a ventilation and heat dissipation space. Keep a distance of at least 15 centimeters between the wall-mounted TV and the wall
3. Since the various interfaces of the TV are basically arranged on the back, various data cables cannot be bent excessively against the wall, otherwise It is easy to break.
4. Be careful during the installation process. Handle the machine with care when moving it, and prepare bedding to prevent scratching the display screen.
5. Follow the requirements of the rack installation instructions and install according to the steps
6. If the display screen has connectors with the speakers and mounting brackets, be careful to distinguish the left and right and the front and back.
7. If you need to connect the speaker cable, you should pay attention to the positive and negative polarity of the speaker cable to prevent the sound of the left and right channels from being in phase.
8. After the display is hung up, you need to use a level ruler to measure it. Adjust the hanger screws so that the display screen is completely in a horizontal position. The translation error of the flat-panel TV installation position should be less than 1cm, and the left and right tilt error should be less than 1 degree.
6. Hiding of wall-mounted TV wires:< /p>
The wall is grooved, the depth is within 70mm, the length is determined according to the height of the floor or TV cabinet, generally from the wall hanging position to the floor socket position, the socket position must be designed to be convenient to use and easy to hide; then, bury the 50MM pipe , preferably PVC pipe; finally, when installing the TV, all wires should pass through the 50MM pipe to the socket location. Regarding the professional laying of wires, it is recommended that users who are not familiar with circuits find professional electricians to do the job more appropriately.< /p>
Problems with wall-mounting TVs:
1. Leave enough space for the interface: Because some signal line plugs are relatively large, such as some HDMI plugs, it is easy to plug them in hard. The interface or plug is damaged. This problem is mostly caused by the use of some unreasonably designed non-original racks. These racks were not designed with too many installation issues in mind, so it is recommended to choose well-designed original racks. .

2. Sort out the messy connections: The TV’s complicated interfaces bring all kinds of annoying connections. How to hide the various interface connections exposed when the TV is hung on the wall should be done during decoration. Take this into consideration when choosing. For example, you can add some baffles or three-dimensional fasteners and other decorations on the side of the TV wall to allow the cables to pass from behind. If it is an environment that has been decorated, you can also consider adding some covering decorations.
3. Choose a reasonable interface layout: The most troublesome part of wall-mounted installation is the connection of signal cables. If all the interfaces are on the back of the fuselage, it will be very troublesome to replace or temporarily add video sources. So choose the TV At the same time, the layout of the interfaces is also an important factor when you consider purchasing a model. The most reasonable design should be on the left and right sides or the lower interface, with most of the interfaces designed. The best way is to equip each interface with an extension cable. In this way, the connection through the wall can be fixed, and you only need to connect it elsewhere when changing the signal source.
TV set-top box installation process
Generally, the connection between the set-top box and the TV is The method is almost the same as the method of connecting DVD and TV. Both of them are to connect the audio and video cable (red, white and yellow cable) to the output interface of the set-top box (the colors must correspond exactly, the same below) and the video input interface of the TV. The only thing is that with DVD The difference is that the signal source of the DVD is the disc, and the signal source of the set-top box is the cable TV signal cable that you originally connected to the TV antenna interface, and then connected it to the signal input interface on the back of the set-top box.
Then, connect the set-top box For the attached smart card (ic card), follow the diagram in the manual and the instructions on the card. When the power switch of the set-top box is not turned on, carefully and correctly insert the card into the card slot (this card must not be inserted or removed when the set-top box is turned on. It cannot be hot-swapped because it is easy to burn out!) After connecting and inserting the card, debug it. The TV status changes to the set-top box status in the same way as the TV status changes to the DVD status. Press the video button (or TV/Video conversion button, or av key, or tv/av key, or tv/video key, or video key), switch to the video state where the set-top box is located. For example, if there are videos 1 and 2, the set-top box may be video 1, and the dvd is video 2. It depends on your connection. The number of the input interface is the video number. After entering the video status of the set-top box, use the set-top box remote control to operate. At this time, refer to the manual for debugging. Generally, search for channels first. Then you can watch or adjust the order of channels. If there is a signal failure : Severe and frequent mosaic images. Or a black screen cannot be viewed normally. After eliminating the factors of arrears, you can call the customer service phone for repair and debugging. When paying, or making up for the fee, or purchasing the program package of the paid TV channel, try not to touch it. Smart card. Use the receipt issued when the set-top box is issued to pay, or use the menu function on the set-top box to bring up the settings menu, check the system information, remember the smart card number, and pay with the card number.
