Software Upgrade

Your TV is capable of finding and updating new
software upgrades over broadcast channels. For
broadcast channels search, TV looks the available
channels stored in your settings. So before software
upgrade search, it is advised to auto search and
update all available channels.
1) Software upgrade search via user
interface
• It is possible manually to check if there is a new
software upgrade for your TV set.
• Simply navigate on your main menu. Choose
Settings and select Other Settings menu. In
Other Settings menu navigate on to the Software
Upgrade item and press OK button to open
Upgrade Options menu.
• In Upgrade Options menu select Scan for upgrade
and press OK button.
• If a new upgrade is found, it starts to download the
upgrade. A progress bar indicates the remaining
download progress. When download completes
with success a message is displayed for reboot to
activate new software. Press OK to continue with
the reboot operation.
2) Background search and upgrade mode
• While TV is connected to Internet, in background it
searches for critical software upgrades. If a critical
software upgrade is found it downloads the upgrade
silently. When download completes with success a
message is displayed for reboot operation to activate
new software. Press OK to continue with the reboot
operation.
3) 3 AM search and upgrade mode
• If Automatic scanning in Upgrade Options menu
is enabled, TV wakes up at 03:00 and searches
broadcast channels for new software upgrade. If new
software is found and downloaded successfully, with
next power up TV opens with new software version.
Note on reboot operation: Reboot is the last step in software
upgrade operation if download of new software is finished
successfully. During reboot TV makes final initialization. In
reboot sequence panel power is closed and front led indicates
the activity with blinking. Around 5 minutes later TV restarts
with new software activated.
• If your TV fails to restart in 10 minutes, unplug power
for 10 minutes and re-plug again. TV should open
with new software safely. If you still can not get
TV working, please kindly repeat unplug and plug
sequence a few times more. If your set still can not
operate, please call the service personnel to fix the
problem for you.
Caution: While led is blinking during reboot do not unplug
your TV's power. Doing this may cause your TV not to
re-open again and can only be fixed by service personnel.

Poor picture

non-earthed audio equipment or neon lights, etc.?
3. Mountains or high buildings can cause double
pictures or ghost images. Sometimes you can
improve the picture quality by changing the
direction of the aerial. Is the picture or teletext
unrecognisable?
4. Check if you have entered the correct frequency.
5. Please retune the channels.
6. The picture quality may degrade when two devices
are connected to the TV at the same time. In such
a case, disconnect one of the devices.
No picture
1. No Picture means that your TV is not receiving a
transmission. Have you selected the correct button
on the remote control? Try once more. Also make
sure the correct input source has been selected.
