The TV does not Turn On

The color and design of the TV and its accessories (including the remote control) and the features may differ depending on

the model or geographical area.

If your TV does not turn on, check whether the remote control sensor is on.

By holding a reflective object like mirror under the TV, you can easily find the remote control sensor.
