Troubleshooting & Tips - Toshiba 43TL5A Series Operating Instructions Manual

3 AM search and upgrade mode
Your TV will search for new upgrades at 3:00 o'clock
if Automatic scanning option is set to Enabled and if
the TV is connected to an aerial signal or to Internet. If
a new software is found and downloaded successfully,
it will be installed at the next power on.
Note: Do not unplug the power cord while led is blinking during
the reboot process. If the TV fails to come on after the upgrade,
unplug, wait for two minutes then plug it back in.
All updates are automatically controlled. If a manual search
is carried out and no software is found then this is the current
version.

Recording unavailable
To record a programme, you should first correctly
connect a USB storage device to your TV, while the
TV is switched off. You should then switch on the TV
to enable the recording feature. If you cannot record,
check the storage device is correctly formatted and
there is sufficient space.
USB is too slow
If a "USB storage device writing speed too slow to
record" 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
storage device does not meet the speed requirements.
Try using a different USB storage device.
