Hello,
I have had a Humax HDR-2000T since Dec last year, and although the standard digital channels are fine, we constantly get problems on all the HD channels with the black screen popping up intermittingly with the message “The receiver is not receiving a signal or the signal is too weak“.
I have manually tuned the individual channels to the strongest/nearest transmitter (Winter Hill) and the signal strength and quality of the HD channels indicated seem totally fine on the on-screen tuning dialogue, with no drop offs (both around the 97%-100 mark).
I have tried three different HDMI cables and if I do put the aerial straight into my Sony Bravia, the HD channels are perfect with no errors. Surely, if this was an aerial issue then I would be getting similar problems on the Bravia?
Having said that, It does seem worse when it is bad weather but the signal strength still remains really strong when I check the tuning menu.
Anyone any advice or have had similar problems?

How far away from Winter Hill are you (if unsure give the first part of your post code)?
I’m south Manchester (M16) and I’ve checked on the coverage checker on digitaluk.co.uk… my most likely transmitter is Winter Hill at 25km, followed by Haslingden (28km), then Glossop which is 20km. It states Winter Hill has good reception followed by Haslingden. Glossop has variable reception.
You should have no trouble In the Chorlton area (M16) with transmissions from Winter Hill. I live slightly further away , WA15, and also receive my broadcasts for Winter Hill.
However, I don’t use a HDR-2000T, but do have three HDR-FoxT2 and are not having any issues with HD or SD transmissions.
Not much help to you, sorry.
Are you sure that the signal quality readings are stable, and don’t drop occasionally? Signal quality is more important than signal strength.
There is a possibility that you have too strong a signal. Simple way to check is add a variable attenuator to the aerial input.
Good call, Graham, I forgot about that.
Thanks all for the advice on this.
Yeah, the signal quality seems stable. When I look at the tuning dialogue screen the signal never drops on either the strength or Quality. I also have no problems putting the aerial straight into the TV. I was swapping between the Sony TV and the Humax earlier today and the Humax was failing every 30 secs where as the TV was totally fine.
I actually have an variable attenuator on there now and it hasn’t made much difference to what it was like before.
I have moved the HDMI to another slot on the TV and it’s been fine all night BUT that doesn’t mean it’s worked. It can go through periods of working fine then not. I have just got a new TV, and it was the same on my older Samsung.
The HDMI lead does cross over a Netgear router, so does anyone think that there could be any problems there? I know it’s grasping at straws but it does seem a little odd as the Humax just feels really sensitive with HD. I have ordered a couple more HDMI leads to see if they work better.
The router could well be an issue. Simple answer is turn it off and see if you still have the issue. Not likely to be the hdmi, rather the proximity of the router to the Humax box.
Thanks, I’ll try turning off the router the next time it happens, and see if that’s affecting things.
Or sometimes a ‘wall-wart’ of a plug-in power supply transformer could be failing causing RF interference to be generated, either airborne or in the mains wiring.

Thanks all things to check. It’s doing it again this morning, and the weather is terrible—really windy etc. Maybe it has something to do with that. It was fine last night.
Looking on the Manual search now in really bad weather…
channel 54
Frequency 738000
Transmission DVB-T2
Bandwidth 8MHz
Network Search off
… the strength and quality are both at 100%, but then keeps on flashing to 0% every 5 or 6 secs. Could this be the aerial even though it works fine with the Bravia? or could it be the actual box?

I’ve looked at the variable attenuator and I think you are right. Even though I had just plugged it into the aerial and then into the box, I now realise that there is a small red dial on the back. When I rotate this fully (not sure on the direction) the signal strength goes from 100% to 97/98% which stops the HD signal cutting out. Pretty naive of me but I’m not 100% on these things.
Thanks everyone for all the help—fingers crossed, hopefully this has solved this.
Hi I have had my box in this house for 2 years without any problems with HD but this last week I cant get HD bbc or ITV. I can get then fine if I tune into the TV as the source so I cant see why any problem with arial. There was a major upgrade about 4 weeks ago and the channel numbers changed. I noticed my digital radio had problems after the upgrade but is fine now.I have no idea what a variable attenuator is but did it work? I was on holiday the last 3 weeks and it only recorded for one week and nothing for the following two weeks, I expect it is all linked. All help gratefully received

The post above confirms it worked for Matmcr, but it was clear from his original post there was a good chance he had very high signal levels as he lived very close to a main power transmitter.
I take it you have retuned the TV following the changes.
