Troubleshooting 09
The picture or sound keep
breaking up.
There are several possible causes of this type of problem.
Your signal may be weak, you may have an old, low-
performance or damaged aerial, or the cable between your
aerial and TV may be damaged. Check for any obvious damage
to the aerial and cables and make sure that the connectors
are properly fitted. If this does not work, get a professional to
check installation – your aerial may provide a better signal if it is
moved somewhere else.
Please remember that older aerials and indoor aerials aren’t as
effective as new outdoor and roof aerials. Or, try using a signal
amplifier or booster to improve the reception. Check the digital
TV coverage in your area. For more information about digital TV
reception, please visit www.freeview.co.uk

Some TV channels are not available in every area. For more

channels again. Please read the section about channel tuning.
I cannot see digital

moved the digital box to a
different house.
Scan for channels again. Please read the section about channel

able to receive digital TV or that there is a poor signal in your
area. For more information about digital TV reception, please

I set 5 recordings to a
device but only 3 were
recorded.
This could have happened for various reasons:
The USB device could have been removed during recording.
The USB device could have been run out of space when
recording.
To avoid this problem in future refer to the ‘Schedule record
summary’. This helps you view scheduled recordings in periods
of 24 hrs., 1 week, 2 weeks or 4 weeks.
Make sure you have USB devices with enough free space
inserted when a recording is scheduled.
The green light is not
turned on when the USB
device is inserted.
Press [PLAY] to view the ‘Recorded programmes list’. The
screen will show one of the following messages - unformatted
or device is too slow to use. Format the device or insert a
compatible device.
