off. You should then switch on the TV to enable
recording feature. Otherwise, recording feature will
not be available. If you cannot perform recording, try
switching off the TV and then re-inserting the USB
device while the TV is switched off.
USB Is too Slow
If “USB is too slow” message is displayed on the
screen while starting a recording, try restarting
the recording. If you still get the same error, it is
possible that your USB disk does not meet the speed
requirements. Try connecting another USB disk.
Internet Connection Not Available / DLNA Mode
Not Operating
If the MAC address (a unique identifier number) of
your PC or modem has been permanently registered,
it is possible that your TV might not connect to
the internet. In such a case, the MAC address is
authenticated each time when you connect to the
internet. This is a precaution against unauthorized
access. Since your TV has its own MAC address,
your internet service provider cannot validate the MAC
address of your TV. For this reason, your TV cannot
connect to the internet. Contact your internet service
provider and request information on how to connect
a different device, such as your TV, to the internet.
It is also possible that the connection may not be
available due to a firewall problem. If you think
this causes your problem, contact your internet
service provider. A firewall might be the reason of a
connectivity and discovery problem while using the TV
in DLNA mode or while browsing via DLNA.
Invalid Domain
Check if the ethernet cable is connected properly.
Check if the Network settings are correct.
Ensure that you have already logged on to your PC
with an authorized username/password and also
ensure that your domain is active, prior to sharing
any files in your DLNA server program on your PC. If
the domain is invalid, this might cause problems while
browsing files in DLNA mode.
The TV sometimes makes a cracking
sound.
This is not a malfunction. This happens when the
cabinet slightly expands or contracts according to the
changes in the ambient temperature. This does not
affect the TV’s performance.
Miracast image/audio cannot be output to
the TV.
Check if the pairing is made properly.
