TROUBLESHOOTING
To help you diagnose what your problem is, it might be useful to know the position of the digital transmitters, as well as the UHF channels used.
Important: DIGITAL TV SIGNALS ARE NOT AS
FORGIVING AS ANALOGUE SIGNAL. It tends to break into blocks when a weak signal is present. It also presents no video
or audio during poor signal.
The table below provides guidelines with what possible problem can occur.
If it is a signal issue from your antenna you may have to call your local TV installer.
Symptom Possible causes Solution(s) to try
You receive the analogue channels perfectly, but not any digital one. You live in a flat.
Your collective antenna system is not adapted to terrestrial digital system.
Contact your owner or managing agent.
You receive the analogue channels perfectly, but not any digital one.
Your geographical zone is not covered by terrestrial digital system yet.
There is no solution immediately.
You will have to wait for your zone to be covered.
You receive some digital channels correctly, but some others are badly transmitted, or not transmitted at all.
Regarding the channels you receive, the reception level is not very high. The analogue image is not perfect.
You receive all the digital channels, but the reception is disrupted sometimes (when another electrical appliance switches on, for instance).
You are too far from the transmitter.
There are interferences
You may call an antenna installer to improve your signal or if you think you are in a black spot you may have to consider satellite TV
1 – Change the TV cable going from the TV plug to your terminal and try a shielded one.
2 – Switch the accessories
(dividers, derivative devices) with shielded products.
3 – Change the cable between the antenna and the plug.
Your reception is correct most of the time, but gets disrupted when it is raining, or sometimes apparently at random.
Your signal is weak and on the threshold ( cliff effect )
Get a more powerful antenna.
