Hi, I understand that Bbc4hd is moving tomorrow ( 19th January ) and I need to retune.. unfortunately I have no idea how to do this! My Humax model is FVP-4000T. There is no menu button on the remote.

Do you have a converter box for the new all digital TV signals? You need one.

This could be too much signal thanks to the Freeview retunes going on. Your aerial is more sensitive at some frequencies, so there's more signal power higher up the frequency range. The signals for BBC and ITV are among the strongest ones broadcast. If they are now at a point on the aerial's range where they are too strong for the TV then the tuner will over-saturate. The result is the same as no signal.


Have a look online for a Variable Signal Attenuator. It's a device that can be added to a aerial signal cable just before it goes in to the tuner. The adjuster allows the signal level to be reduced. Watch the TV's signal quality and signal level displays if it has them. As signal level (power) reduces you'll actually see signal quality increase. If you go too far then quality will start to go down again. The optimum point is where quality is highest.

You will need to manually tune to your preferred transmitter. The Humax will tune to the first decent signals it finds, so if signals from the Welsh transmitter are good and found before the transmitter you want, it will use them.

Or, you may be able to unlpug the aerial, start the auto retune, then replace the aerial after about 25% of the scan completes. You may need to adjust the % before replacing the aerial to ensure that only (and all) wanted channels are received.

There should be a channel editing part, you just need repostion the channels. It will probably have moved the BBC channels you want elswhere on the list of channels.

sounds like you are now picking up 2 transmitters, 1 Winter Hill, 1 welsh- Moel y parc. Due to the increased strength of the new Moel y parc signal
see http://www.digitaluk.co.uk/postcodechecker/main/trade/pr25+3ss/1/0

You can see its the channel 46 in orange thats your problem
Do the same retune but unplug the aerial until it gets past 46 so that it only finds the channels 56 and above that are from Winter Hill.
Bad news is that for you it gets worse when the extra channels come on next month. Looking at the aerial and maybe playing with attenuators might filter out the Welsh one

Not a complete solution but after much fruitless fiddling through the menu I eventually found that the programmes were actually there but under different channel numbers.
I searched a long way down the LIST of channels (on remote) The BBC1 channel I want is now 800 BBC. Selecting 1 on the remote still brings up BBC Wales.
This applies to my Humax 8000T PVR - I can't comment on other makes of Freeview box.

The Humax PVR-150T will definitely have problems using an indoor set top aerial; this is true of almost all Freeview receivers. Freeview signals are typically hundreds of times weaker than terrestrial transmissions and if you've managed with a set top aerial so far it's been working more by luck than design. I find that most set top aerials are so badly made that they're often faulty when new, but as most tend to flogged cheaply at markets and car boot sales the supply chain has no incentive to improve the product.

There has recently been a national Freeview retune, to complete this correctly your box needs the kind of solid and reliable signal which you cannot get with a set top aerial. Some receivers had compatibility issues with the retune and in many cases manufacturers broadcast OAD's (Over Air Downloads) to update the firmware in the boxes to be compatible. OAD's almost never successfully install via set top aerials.

There is an official list of Freeview devices which are known to have problems with the retune; unfortunately it has not proven to be a comprehensive list. The Humax MG-TU1 is one of those which have had problems and from memory it's closely related to your Humax PVR. The official advice is that you contact Humax directly on 0870 247 8800, but they'll probably instruct you to test your box using the aerial system it's designed to use before they'll be interested in offering further assistance.

Hi, I switch on the humaxand it says -retune. I retune and it finds the channels but will not retain when OK is pressed. It shows the correct postcodebut after numerous attempts it still fails to hold the channels. Please help

Go to the following link and follow the instructions for your model.
