Konka TV has a black screen of advertisements as soon as it is turned on.

If you update or install software that is not included in the system, updating or installing applications will cause this situation. If boot direct is set, 95% of software updates will be black, and if other software is updated, there is a 50% chance. Suggested solution: 1. Boot into the advertising black screen. If the black screen cannot enter the system after two or three minutes, repeat the above steps three to five times. After a few minutes, the system can be used normally. After normal, you can go in and set the retained software to restore the factory settings, which is safer. If it fails, you can choose to brush the machine. 2. After decompression, put it in the root directory of the U disk, that is, directly open the interface of the U disk. Then plug in the power cord of the TV and don't turn on the TV switch! Because the TV remote control doesn't work at this time, you need to find the physical buttons on the TV. Then press and hold the standby button and volume on the TV at the same time-about fifteen seconds, and turn on the TV on/off button without letting go. Then the kKtv logo will appear, enter the advertisement, and release your hand when entering the advertisement for about five seconds. Then, because the screen will go black after the TV commercial, don't move, just let it stand by and watch, and then the TV will refresh.
