I. Tv hardware failure
One, black screen and sound
The first step should be to check the back-linking of the television, whether each wire is inserted in a specific position and to confirm that each entry point was well exposed and did not produce any relaxation. If caused by the looseness of the wire, it is sufficient to fix it。
Second, hardware problems can also cause black screens of television, including electrical circuit failure of monitors, screen failure, and line failure. Once the problem of the plug is excluded, the maintenance staff may be contacted。
2. The tv is suddenly black and unable to start
In this case, if the power light is not on, it means that the television was suddenly black-screened because of power connection problems. At this point, it is possible to look at home electricity, whether the power plugs are loose and whether the power lines fail。
Ii. Tv software failures
1. Smart tv dead, carton
There are more reasons for the death of television sets, such as the poor optimization of the television vendor system, the small size of the memory of the television station, and the chronic use of waste. When the tv carton is found, users can clean up the tv memory by downloading it from the bayside market。
Once software is installed, more checks can be made on whether there are apk packages 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 are currently prohibited from installing 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 the software is installed, there is often an error in the resolution of the package and problems may arise as a result of: first, because the complete installation package was not downloaded by the user during the download, it can be re-installed only after re-downloading。
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。
