The TV won't be powered on. What happened?

The TV cannot be turned on for the following reasons:

1. Power failure: Power failure of the TV may cause the TV to fail to start, so it is necessary to check whether the power switch, power cord and power plug of the TV are normal.

2. Overload: When the TV is connected with too many devices, such as DVD players, computers, projectors, etc. The TV can't be turned on normally due to the heavy load, so some devices need to be disconnected.

3. Circuit failure: The TV circuit board may fail, resulting in the TV not being turned on normally. Need to find a professional TV maintenance personnel for inspection and maintenance.

4. Unstable voltage: When the voltage is unstable, such as short-term power failure or low voltage, the TV may not be turned on normally.

5. Remote control failure: the remote control fails, and the TV can't operate, resulting in the TV not being turned on. You need to change the remote control or turn off the TV manually.

6. Loose plug: The plug between the TV and the power plug may be loose, so that the TV cannot be turned on and needs to be plugged in again.

When using TV in daily life, keep the power switch clean, avoid the failure caused by cable aging, avoid over-unplugging the power cord, and regularly check the connection state between TV and plug to ensure voltage stability. If the above methods can't solve the problem, you need to contact professional TV maintenance personnel for inspection and maintenance.
