Tv has always been an indispensable part of the living room for all. Whether it's a red and white machine that used to play as a child, or later the popular television drama, it has become a valuable memory. While television is no longer as home-based as before, and young people prefer mobile phones, computers, etc., for the time being, the further development of television performances by television producers and the increasing content have brought many people back to the screen. Now that television is more functional, the ease of use is enhanced, but what should we do when television software and hardware fail? Today, let's show you the story。
Tv hardware failure
One, black screen and sound
The use of black screens and sound is due mainly to problems with the source of the television signal or hardware, which are treated differently. The first step should be to check the back-of-the-television line, whether each line is inserted in a specific position and to confirm that each entry point is well exposed and does not produce any relaxation. If caused by the looseness of the wire, it is sufficient to fix it. In the case of an error in the placement of the wire, for example, it is possible to check whether the tv is connected to the top box, dvd, etc. If the yellow video line is not connected in the right way, it will give rise to a black screen situation. In addition, the negative exposure of video wires from the yellow interface can result in a black screen situation。
Second, hardware problems can also cause black screens of television, including electrical circuit failure of monitors, screen failure, and line failure. When the problem of the plug is excluded, the relevant post-sales maintenance staff may be contacted. Such problems require testing of the dismantling machines, so maintenance is generally longer。
2. The tv is suddenly black and unable to start
If the screen is suddenly black when watching the television at home and cannot be activated again, the electrical light on the television can be observed first. If the power signal is not on, it means that the television was suddenly black-screened because of the power connection problem. At this point, it is possible to look at the situation in the home shop, whether the power plugs are loose or whether the power lines are malfunctioning。
If at this time the power light on the television remains on, it means that the black screen of the television is caused by hardware failure. Multiple locations, including main panel circuits, screen liners, screen failures and other parts malfunctions, have the potential to fail. For example, electrical failure is one of the more common types of failure, which, when the mask is turned on, means that there is a problem with the section if it is highlighted. The television can continue to be used only after the electricity is replaced. If the internal structure of the television is not known, the user can contact the post-sales maintenance staff for testing or routine maintenance。
3. Television
Television screens are also one of the most common television failures, and the reasons for this are generally divided into several categories. The first is the question of signals, most of which are currently receiving on top of the machine, and the signal currently used is a digital one, so that problems with digital signals can affect television images and the appearance of images can create a screen. At the same time, if there is a problem with bad signals, the images will not flow, or there will be a flower-screened marseille。
The bouquet failure on television is also related to the main panel, where problems are prevalent. Once it has been determined that there is no problem with the signal, professionals can be contacted for maintenance. The maintenance staff will need to reweld the break points and fix the main plate before they can completely leave the television screen. In addition, television screens may also be associated with display damage and need to be replaced or repaired separately。
Tv software failure
In fact, the majority of television products today have smart features and, while providing easy access, they also pose software problems. Now, let's get this over with。
1 smart tv dead, carton
For smart television, the long-term use often results in the death of the carton. The system of smart television, with the widespread use of the android system, has a number of ways to mitigate or resolve the dead-end, carton phenomenon。
There are more dead televisions, more clouds in cardon, such as poor optimization of the television vendor system, smaller memory in the permanent backstage of television, and excessive long-term use of garbage. When the tv carton is found, the user can clean up the memory more and kill some useless or sneaky memory to enhance the system. Once software is installed, more checks can be made on whether or not the apk installation package is left on the television system, as some software will be left on the system after automatic upgrade and will need to be cleaned up in a timely manner。
2. Cannot install software applications
Many television manufacturers currently order the prohibition of installation of software applications via usb connections, and some default that television software cannot be installed otherwise. In fact, it is only necessary to open this option so that it can be installed through usb. We first need to access the settings in the system, find the corresponding items and turn the switch on。
In addition, if it is found that a third-party application cannot be installed, the installation option for a third-party application can be found in the settings and opened, and the third-party software can be installed。
3. Problems with smart television resolution packages
When we install the software, there is often an error in the resolution of the package and problems may arise as a result of: the first is that the installation package, which the user did not download during the download, can be installed again after the new download. Second, the installation packages downloaded by users may not match the version of the system on television. At this point, it is necessary to check whether the software requires the system and can be upgraded and installed. In addition, it may be that the installed package is too large for the television configuration to support its installation。
For television products, while prices are low today, the technical skills available for actual television products are not low. Attention to the maintenance of television in its use ensures that television is not problematic for long periods of time。
