Reception Problems
When you purchased your DVR, your dealer should have checked your postcode to ensure that
you can receive Digital TV. If you wish to check this yourself, please look on the internet
websites:-
www.freeview.co.uk
or
www.dtg.org.uk/consumer.
Once you have established that your area should be able to receive digital TV, there are a few
reasons why you may be experiencing problems.
•
Your current aerial and cabling may not be able to receive all the digital channels
due to its age and condition. Now is the time to renew them. Thomson
recommends the use of CAI “Benchmarked” aerials. Look for the logo.
Always use good quality, double screened aerial cable. e.g. CT100 coaxial cable.
•
In your location the digital channels may be transmitted on different frequencies to your
existing analogue signals and you may need a different type of aerial to receive them.
Check the ‘group’ of your aerial, you may need a ‘wideband’ one.
•
The new digital channels may be transmitted from a new transmitter and if this is the case
the aerial would have to be re-aligned. Alternatively, add a second aerial to your system.
•
If you need to use a mast-head amplifier, make sure that it is a digitally compatible one and
that it is a close to the aerial as possible.
•
In some blocks of flats, filters may be in use that will interfere with digital signals. Consult
with your landlord if you have difficulties.
•
Indoor or window mounted aerials are not recommended, except in areas where the signal
is extremely strong.
•
Your aerial could be too high. Try adjusting the height of the aerial to avoid picking up
unwanted signals from other transmitters.
•
If you live near a road, the passing traffic may cause problems. Try pointing the aerial at an
upward angle over the road, this helps reduce engine interference picked up by the aerial.
•
If you get periodic picture losses, this could be due to electrical interference picked up in
your house. This could be from a central heating thermostat, a fridge/freezer, or any other
item with a motor. Try switching these appliances off temporarily to establish what is
causing the problem. Then replace the problem item.
•
If your aerial comes into your room via an aerial connection point (socket), replace it with
a good quality shielded one. This will help prevent electrical noise entering your aerial.
