External Device Connection Issues
Problem Possible Solutions
I have connected an external
source to my TV but I get no
picture and/or sound.
Check that the connection between the external device and your
TV is not loose.
Ensure you have selected the correct input source.
There is no signal or weak
signal in the cable box.
If there is no signal occasionally, unplug the cable from the TV
and plug it back in after 60 seconds.
If there is no signal, or the signal cannot be restored, go to
Menu
> HDMI Format if you select HDMI as input, to confirm
whether the signal can be recognized.
Change to another HDMI port.
Replace the HDMI cable.
There is no sound.
Check if the Audio Out option in the menu is ARC/eARC, if not,
you need to check whether the external power amplifier device
is connected to the ARC port or optical port of the TV.
Go to Home
> Settings > Sound > Advanced Settings > Digital
Audio Out. You can try to select PCM, Dolby Digital, or Dolby
Digital Plus.
Whether the power amplifier device port is connected correctly.
If you select HDMI as input, try Menu
> HDMI Format.
The remote control does not
work.
Confirm that TV still has power and is operational.
Check that the batteries are correctly installed.
Place new batteries in the remote control.
If some buttons don't work, but the volume buttons work
normally, the problem is likely with the application.
Media Files
Problem Possible Solutions
Some files can’t be played.
Check the compatibility tables in the Appendix. Most files can be
played back, but you might experience problems with corrupted
files, or with files that have high bitrate, unsupported resolution,
unsupported container, or unsupported codec.
