Check if you can operate the TV normally using the supplied remote control. If the TV turns on and off using the supplied remote control, then the TV is functioning properly.
If the TV is working properly with its own remote, and you can't turn the TV on or off using the remote for an external device, check the following:
Point the IR transmitter of the external device's remote directly at the IR sensor of the TV.
NOTE: Refer to the manual for the TV and the manual for the external device (or contact customer support) for the exact locations of the IR sensor and IR transmitter.
- Check the external device manual or contact customer support to make sure the external device is operating properly, and see if it supports the CEC (Consumer Electronics Control) function of an HDMI® connected device.
NOTE: The CEC function may not be supported by the external device, may not be working properly due to software issues, or if the remote or external device is malfunctioning.
