There are many reasons why the Sony TV cannot be turned on, it may be improper use, or the TV itself may be faulty. Here are the specific reasons and solutions:
1. It may be that the Sony TV is not connected to the power supply or the TV switch is not turned on. You can check whether the socket connected to the TV is powered on (whether the socket indicator light is on), and use the TV physical switch key to turn on the TV (whether the TV indicator light is on).
2. It may be that the Sony TV is in a standby state. You can use the on/off key or standby key of the TV remote control to turn on the TV screen, or you can directly disconnect the TV power and then plug it in again to turn it on.
3. It may be that the Sony TV screen cable is faulty or the circuit board parts are faulty. You need to contact the TV after-sales service to detect the source of the problem and replace the corresponding parts.
