Can anyone help. Lost BBC 1. Just shows bad or no signal message. BBC1 HD OK and also if I take out the Humax and just run the TV straight from the aerial then BBC 1 reappears. Another factor is that I have another TV with an old digistream box which picks up BBC1 and BB1 HD without a problem.
Got to be the Humax...hasn't it ?
What is the signal strength and quality? Humax receivers are known to be sensitive and can be overloaded with a strong signal.
Might be simply too strong a signal (Humax Freeview boxes have sensitive tuners). Try fitting a variable attenuator.
Welcome to our forum.
Thanks for that. If we are talking about signals being too strong, I am fairly sure that some years ago when we had the digital switchover we had some issues and when we had a new TV we had an inline booster fitted. Might be worth me removing that first to see if it makes a difference. Also if I want to check individual signal strengths and qualities how do I find that on the menu.
Thanks

That's a good idea. The power output of the digital transmitters was greatly increased at the time the analogue network was switched off (DSO). Over the weekend due to atmospheric conditions you were likely to be getting higher levels than usual. In some cases if a distant transmitter using the same UHF carrier as one from your local transmitter came into range, you got big problems with that Mux.
To check signal levels and quality tune to any channel on a Mux and bring up your diagnostics menu in settings.
Not having your box guessing it will be in settings and say something like diagnostics or signal test or similar.
I don't have one of these units so this is a guess based upon other models. Tune to BBC 1 then go into setup > System - it might be listed a system info > signal.

Signal Test
I am line-of-sight from the Sutton Coldfield transmitter and get about 91% on the Signal Test. There are no obvious problems with my FVP4000T.
The 4000T is also feeding the LG TV with signal. I do have an adjustable attenuator on that, set to about 90%. That was on the advice of an LG tech. support bod for no particularly good reason as far as I could tell at the time.
Hope that helps!
