Hello

Does anyone know whats causing this interference on my TV reception (hopefully link will work for video)


I've mostly noticed it on BBC1 and I thought at first it was interference during live outside broadcasts so didn't really think much of it at the time, but its happening more frequently now and I cant seem to find anything on google to suggest whats wrong.

I've retuned - I use freeview from an aerial
I've checked the aerial cable in the back of the TV
I've checked for any transmitter faults (none)
TV is 18 months old

It doesn't seem to happen on other channels - just after I took this video I watched BBC2 for a while and nothing.

Thank you

    Your TV obviously isn't a fan of The One Show.  Its a coded message to tell you to stop watching it ;)

    This might of interest:

    Possibly the TV is tuned to a different region of BBC1?

    Hard to tell as it is such a short video. If you said it was happening on all channels, I would have said you have a fault with your tv.

     Freeview interference will cause blocking or freezing or total momentary loss of signal. We get a lot of low flying helicopters and motor cycles can cause these symptoms as they pass by our house.

    So, to recap this to me does not appear to be interreference related.

    One more thing to add, are your neighbours having any issues?

    That's not going to cause the effect mentioned.  On Freeview you get channel 1 and 101.  Unless you're fortunate enough to live in a crossover area that straddles the edges of two, sometimes three regions that is, but even if you're looking at the wrong one that's too far away from where you are, you're more likely to see nothing at all than "your" region on 1.

    BBC ONE and BBC TWO are on the one single multiplex frequency in any single location for SD, and similarly one (different) mux frequency for BBC TWO.  So whatever is causing it should (must) equally affect both 1 and 2 (and other TV channels on the same frequency / in the same multiplex of channels).

    Use the TV's signal strength quality metering to check things?  Check for stored versions of BBC 1 etc.,. in the 800s that might be better /less prone to disruption?  18 month old set will be HD capable so watch 101 (HD) rather than 1 (SD)  - or vice versa - to see if only one is affected or both?

    It does look like a form of variable reception (dips or excessive signal overload) or possibly electrical interference disrupting the signal, though.  Finding the cause and the cure is another matter.  Mobile phone polling can give similar-ish symptoms so worth switching any off for a period when it's 'happening' to see if it stops, and re-starts when they are switched on again.

    As previously stated it's not really a long enough video to pinpoint the cause.
    The only similar localised interference I have come across were someone using a microwave oven nearby and a faulty 3 way motorised diverter valve on the central heating.
    Back in the days of analogue tv there were regular occurences of interference from transmitting equipment from nearby police/fire/ambulance stations causing problems.

    Yes, that's right. The quality of reception of an analog TV signal (including T2) is influenced by radio waves. It even happens that some channel has a weak signal and it is enough for a person to stand in the path of the signal, as the broadcast is interrupted.
