This will occur if the television tuner is not set to receive the appropriate type of broadcast. For example, if you are using an over-the-air antenna, the TV must be set to Antenna or CABLE OFF in the menu; if you are using cable (without a cable box), then the TV must be set to Cable or CABLE ON in the menu. Once you have selected the correct setting, the TV will need to be auto programmed.
IMPORTANT: The procedure to set the TV to use antenna or cable and perform an auto program will vary by television model. Consult the instruction manual of the TV for specific information. Os manuais são postados em seu modelo de página de suporte.
NOTE: The original TV remote control may be required to auto program some televisions.
