/1. When watching TV, the TV will return to the main menu. It is possible that the button set by the remote controller leads to unstable signal output, so the TV returns to the main menu page, and don't touch the remote controller at will. If you accidentally touch the remote control, please press the back button again to return to the TV you want to watch. 2. If the TV system is garbled, you need to repair the TV. When you fix the TV, you can't fix it yourself. You need to contact a professional service person to repair the TV at home. The TV will be reset during maintenance, and the mode of the TV will be changed after the reset, so that the TV will not return to the main menu. 3. When the TV jumps back to the main menu, the voltage may be unstable. Adjust the voltage to be stable or measure with a multimeter. Is the voltage entering the TV set stable? If the voltage is unstable, then there must be something wrong with the voltage.
