General reasons and treatment methods of no image after TV is turned on;
1. Check whether the TV is turned on and the power button is turned on. If you don't turn it on, turn it on and the problem will be solved.
2. Check whether the power button of the TV remote controller is pressed to turn off the screen display of the TV, so that the TV is in standby state. Press the power button of the remote control again to start the screen and return to the normal state.
3. Check whether there is any problem with the signal source input of the TV set, such as whether the connection between the TV set and cable TV signal, digital TV signal or DVD player is normal. After normal connection, switch the TV to the corresponding signal source mode and return to normal.
4. After the above methods are checked, the TV still doesn't respond. Generally, it is judged that the TV is unresponsive due to the hardware failure of the TV, including the switch circuit failure of the main board, the screen line failure, the screen failure or the failure of the picture tube, the base and other components. It is recommended to contact TV after-sales service for comprehensive inspection and warranty. Generally, the maintenance cost should be judged according to the faulty parts.
