If the remote control sensor turns off when you press the power button, your TV is correctly connected to the power
supply.
If the TV screen is still blank, softly tap it with your finger. If the part of the screen you tapped on blinks, your TV is
correctly connected to the power supply.
On the remote control, press the
button. When the Home Screen appears, the TV is turned on but the connected
external device does not work or is not connected correctly.
