For everyone, TV has always been an integral part of the living room. Whether it was a red-and-white machine that was often played at a young age or a popular TV series later, it has become a precious memory. Although TV is no longer concerned about family as it is now, young people are also more interested in mobile phones, computers and other devices. However, TV manufacturers' further development of TV performance and the continuous enrichment of content have brought many people back Screen currently. Nowadays, TVs have many functions and their convenience has been improved. But how do we deal with TV hardware and software failures? Today, let Xiaobian take you to find out.
TV hardware failure
1. The black screen of the TV and the black screen of the sound TV and the sound are mainly caused by the TV signal source or hardware problems. The processing methods of the two are different. First of all, check the condition of the line behind the TV. Check whether each type of wire is inserted at a specific position and confirm that the socket of each type of plug is in good contact without loosening. If it is due to loose wire, it can be fixed. On the other hand, if it is because the position of the wire is incorrectly inserted, it is possible to check whether or not the TV is connected to a set-top box, a DVD, or the like using the AV cable. If the yellow video cable is not connected correctly, it will cause a black screen. In addition, if the yellow line video cable is in poor contact, it will cause a black screen.
Second, hardware problems can also cause TV black screens, including display circuit failures, display failures, and cable faults. After troubleshooting the socket section, contact the relevant after-sales service personnel. The occurrence of such problems requires the disassembly inspection, so the maintenance time is generally longer.
2, the TV suddenly black screen and can not start If you suddenly see a black screen at home and can not start again, you can first observe the TV's power indicator. If the power indicator is not on, it means that the TV is suddenly off due to a power connection problem. At this point you can look at the situation in the store at home, if the power plug is loose, and if the power cord is faulty.
If the TV's power indicator is still on at this time, the black screen is due to a hardware failure. Multiple parts, including motherboard circuits, screen cables, screen failures, and other parts failures, have the potential for failure. For example, capacitive fault is one of the more common types of faults. If the capacitor is found to be convex after turning on the back cover of the TV, it means that there is a problem in this part. Only need to replace the capacitor, the TV can continue to use. If you do not understand the internal structure of the TV, users can contact after-sale maintenance personnel for testing or routine maintenance.
3, TV Huaping TV Huaping is also one of the common TV failures, causing such reasons are generally divided into several categories. The first problem is the signal. At present, most TVs use the set-top box to receive signals. Currently, the signals used are digital signals. Digital signal generation problems will affect the TV screens, and the presented images will also produce Huaping. At the same time, if there is a problem with poor signal, the image will not be smooth or a mosaic phenomenon will occur.
TV screen failures are also related to the motherboard, and the problem is common in motherboard soldering faults. After confirming that there is no problem with the signal, you can contact a professional for repair. Maintenance personnel need to re-weld the breakpoints, and after the motherboard is repaired, they can completely bid farewell to the TV screen. In addition, the TV screen may also be related to the destruction of the display screen, and the display screen needs to be replaced or repaired separately.
TV software failures In fact, most television products today have intelligent functions, and while providing convenient operation methods, they also bring about some software problems. Next, let Xiaobian take everyone to find out.
1, smart TV crashes, Caton for smart TVs, long-term use often result in crashes, Caton phenomenon. The smart TV system generally adopts the Android system, which can reduce or solve the phenomenon of crashes and stalls through some methods.
There are many cloud factors that cause TV crashes and Caton. For example, TV manufacturers have poor system optimization, TV resident in the back office causes memory to become smaller, and there is too much garbage for long-term use. When the TV is found to be stuck, the user can clean up the memory and kill some useless or stolen memory to improve system memory. Usually, after the software is installed, it can be checked whether there is an APK installation package left in the TV system. This is because some software will leave the installation package in the system after the automatic upgrade and need to be cleaned in time.
2. Cannot install software applications Many TV manufacturers currently have orders to prohibit the installation of software applications via USB connections. Some manufacturers have default TV software that cannot be installed in any other way. But in fact, just to turn this option on, you can install it via USB. We first need to enter the setup options in the system, find the corresponding item, and turn this switch on.
In addition, if you find that you cannot install a third-party application, you can find the installation options for the third-party application in Settings and open this option to install the third-party software.
3, Smart TV parsing package problems When we install the software, parsing package errors often occur, there are problems, may be due to the following several reasons. The first is because the user did not download the completed installation package during the download process, and can be installed again after the new download. Second, the installation package downloaded by the user may not match the system version of the TV. In this case, you need to check whether the software has requirements on the system. You can upgrade the TV and install it. In addition, it may be because the file of the installation package is too large and the configuration of the TV is insufficient to support its installation.
For television products, although the price is lower today, the technical performance of actual TV products is not low. Pay attention to the maintenance of the TV at any time during use to ensure that the TV can be used without problems for a long time.
