Just a recap: the message came up to retune, which I did, no problem. Then the next day, all channels disappeared and I had the msg: ‘The receiver is not receiving a signal or the signal is too weak’. I spoke to Freeview who thought I may be tuning to Midhurst and not Rowbridge (IOW), so suggested I tried manually retuning which I did. Over the next few days, the signal was completely random, but mostly off for several hours.
At800 sent a chap to check the aerial, he found no problem, we reset the box, all OK. Only to go off again later. I had a TV engineer in, no progress except he was sure the problem lay with the Humax box. I spoke to the Humax help desk two days ago, and they gave me detailed instructions to reboot the box and manually retune, which I followed to the letter – all working. Until several hours later when all channels went again.
I have had this setup for five years, it has a Panasonic TXL42ET5B TV and separate DVD. I have never had one problem – until that damned retune.
Any advice would be wonderful.
Hi there Fender Bender, thank you for your response.
At the moment, there is 0% signal for all channels on the manual retune (this is for the following channels – 24, 27, 25, 22, 28, 29, 21, 31, 37 as advised by the Humax help desk).
However, this has not been the case since the retune, it is completely unpredictable. When the aerial chap was here, all was working and he was slightly concerned that the readings were a tad high. With me doing nothing to the Humax box/TV, it sometimes has the channels/signal available and sometimes not. However, if I plug the aerial into the TV when the Humax box has failed, all is stable, no problems at all.
The box is five years old, but if the tuner has started to play up, it just seems a huge coincidence that it has started to play up only since that last retune (within 24 hours, though was fine immediately afterwards).
Is there any further advice, please do let me know as it would be good to get the box back, thank you in advance.
Just for information, these are the instructions from the Help Desk (explicitly followed on more than one occasion now
):• Press MENU on the remote,

• The unit will restart, please allow up to a minute for this to happen,
• Please choose your preferred language,
• Please adjust any display settings as necessary and then choose NEXT,
• Stop the automatic search before any results are found,
• When presented with the message “Do you want to save the channels searched up to this point?” please choose NO
• Apply any network settings if needed – Only applies to those with Ethernet cable connected, then choose NEXT,
• Please check the settings and choose FINISH,
• When given the message that no channels are available please press the OK button,
• Select “Manual Search” and press OK
• Highlight Channel and press OK
• From the List below select the channel number and press OK,
• Select Search and press OK, once the search is complete save the results
• Repeat the search for all the channel numbers below:
Channel 24
Channel 27
Channel 25
Channel 22
Channel 28
Channel 29
Please Note: When tuning the HD Channel you need to change “Transmission” to DVB-T2, only then will it find the channel,
Channel HD 21
Channel HD 31
Channel HD 37
You may need to fit a variable attenuator. The Humax has sensitive tuners that are easily overloaded.
How far away are you from Rowridge ?
Hi Graham.
Thanks for the swift response. I am 15 miles from Rowbridge apparently (21 miles from Midhurst, as the crow flies in both cases. Midhurst is another transmitter). The TV repair man said that he thought that the Humax box could not cope with the number of new channels, he has seen that a few times apparently, but he had no solution to that, and it tuned OK when he was here. Just went off afterwards.
The aerial man did put something on the aerial cable going into the Humax (or TV) and I think he said it was a filter. I have enclosed a picture.
Would I be better tuning to Midhurst? Not that I know the channels for that.
The examples you sent across, do I need both and would they be positioned onto the aerial cable?
Thank you.

With the greatest respect to the TV repair man, he is talking nonsense. The HDR-FOX T2 is perfectly capable of dealing with the current number of channels. Earlier Humax boxes, the 9200T for instance, do have problems. What is the signal strength and quality as reported by the Humax when tuned to BBC1?

It depends which way your aerial points, because if you’re closer to Rowridge than Midhurst, its likely you are in between the two.
Using manual tune you could see what signal strengths you get for the following channels from Midhurst:
DVB-T: 50, 55, 56, 58 & 59.
DVB-T2: 54.
Edit: The filter you have fitted is to filter out 4G signals that might interfere with the freeview channels.
Martin, sadly there is no signal into the box at all at present, so I cannot answer that. When it was working and the aerial guy was here, he was concerned that it was in the 70% plus range, but once he fitted that filter (?), it went down to below 60%. It was all working then (for a few hours at least). Times fondly remembered….
I will have a go at tuning into those Midhurst channels (thanks FB) and see if I can get a better (any) response. Looking at the aerial on the roof, it does look as if it is pointing in the IOW direction, but nothing to lose by giving it a go.
In defense of the TV repairmen, he may have been alluding to earlier Humax versions.
You don’t need to actually re-tune to Midhurst. Without resetting the box, just scroll down the list of channels on the manual tune screen and see what the signal strength is of each one. Don’t press the Scan button.
Ah, OK, FB, will do. Presently, for the Rowbridge channels, I am getting zero signal strength, which is why I am suspicious of the tuner in the box (as all is OK when the aerial is in the back of the TV).
I will give it a go, thank you.

The attenuator I linked to has f connectors. The adaptor allows you to use the standard Belling Lee TV type connector (alternatively you can fit f connectors to the existing cable – Google how to fit as they are very simple to fit). You can get attenuators with standard belling lee connectors.

As already said the filter you have is a 4G filter. If you remove and then get picture interference simply put it back. Chances are you don’t need it.
The attenuator fits to the coax cable before the Humax rf/aerial in socket.
To tune to Midhurst you would need to realign your aerial.
On your existing aerial are the aerial elements horizontal or vertical ? Rowridge is very unusual in that it has both horizontally and vertical polarised channels.
I’m just wondering whether your problem is a mechanical issue where the aerial cable plugs into the back of the Humax (or the channel 59 box plugs in). I had some issues some time ago with signals coming and going and tracked it to the plug and socket which I tightened up/jiggled about a bit and they seemed to seat better and all was then OK – maybe worth a try.
Hi All.
Trevor, I too thought that maybe the problem was the aerial cable, and have been out, purchased a Monster cable which continues to allow the TV to show brilliant pictures, but sadly, nothing at all via the Humax box. I also did remove that filter box thing, has made no difference to the picture on the TV, it still appears clear as a bell.
When I reset the Humax box and choose to manually retune, for every channel I choose, each comes back with 0% for Strength and 0% for Signal. This is for Rowbridge, Midhurst and even when I choose Auto tune – nothing. This has certainly happened since the requested retune, but it then randomly kept finding the signal and loading the channels. And then losing the signal. Several times. However, this week, it does seem to have packed in completely (the Humax box I mean), as it cannot and will not find a signal, even though all I need to do is switch the aerial cable into the TV and all channels are there, clear as a bell.
It does look like the Humax box has packed up in the tuner department. It is five years old, though I would have hoped for a longer life for it. C’est la vie.
If there are other options, please do let me know. But I am not sure where we can go with the box not recognising the signal from the aerial cable.
I would like to thank you all for your help and advice, I do appreciate it. I think I may have to look for a new PVR 😥
