Finbar:
a) Check which transmitter your on - if you've tuned into the wrong transmitter, then your signal will be rubbish. Heathfield or Midhurst, although Crystal Palace wouldn't be impossible.
b) check each part of the chain from your aerial to the TV/PVR. Humax's actually have very sensitive tuners, so if your getting a rubbish signal and you are tuned into Heathfield, its certainly something to do with your system. people often think that somehow 'they' turn down the signal strength or stop broadcasting certain channels, but of course 'they' dont. The only time there is a weak signal or transmission stops, they will usually tell you, and it will be normally hours, at most. If its weeks, its you.
Losing HD signals is a sign that its your system and that its a weak signal - they often go first.
You could start with the aerial lead from the wall - easy to replace and often the source of the problem, in that its just come lose.

liz krauesslar: Put your postcode into the site, and it will bring up what sort of signal you should get, but almost certainly your system is at fault, and thats why you've lost various channels.
Check your cables, starting from behind the TV. It could be no more than a loose cable connection or a damaged cable. If you can't find any problems and nothing has got better, then you might need to call out a professional.

Ian: Since I assume you've checked signal strength, have you checked to see if the firmware is OK.
I am familiar with the VT30 & VT50, but not the VT4 (import?) , but it must be at least 4-5 years old. It should be fine, but its worth checking it out on AVForum, etc, just to see if its not just you.

Charles Carruthers: Check if the second TV has an HD tuner (model no. would be helpful). Talking Pictures (as has been pointed out again and again) needed an HD tuner to pick it up. So if you havn't got one, your not going to get them.
Also check they are tuned to the same transmitter. If both TV's have HD tuners, but one is tuned to a transmitter that doesn't carry those channels, then that could also explain it. Put your postcode into the site, and we can see if this could happen.
BTW - if one TV is fine without a booster, why is the other one connected to it?

Kay Coleman: Check that your actually tuned to Emley Moor - Digital UK reckon thats your best bet, and at 69km, not too far away. If your set has picked up another transmitter (like Belmont), then your signal might be too low.
Next, check your signal strength on each mux (or group of channels). If they are low to non -existent, then check your cables. If its too high (90%), then thats solvable.
Start with the one from the back of the TV and trace back the signal - if the other TV's in the house are fine (and they are fed from the same aerial, not on Sky), then its likely to be between the point where the signal is split and your TV.
No, an old deep TV is not HD, but you can check quite easily if its the box, the cable or the cable from the ariel to the wall - take the box and lead from the TV, and use them in another TV. Connect the box to the TV via a scart and the aerial lead that your using. If its all fine, its likely to be the wall fitting with your TV or the lead from the aerial to it.
If there is a problem, then its the box or the lead. So change over the lead to one that you know works.If it then does, you've answered your problem.

Freddy: I'm on Waltham, and it seems fine. If your not getting those channels/muxes any more, check two things, which are common problems:
a) that the TV hasn't locked on instead onto the Nottingham Light transmitter. As the page above says, it may not do the channels your looking for. Since Nottingham's frequencies start at Ch27, and Waltham's starts at Ch49, even though they are in different directions, thats a real possibility.
b) Check your cables. If your losing muxes, its usually your system. Could be a loose connection or cable - start with the back of the TV. If you are tuned to Waltham, then its probably this.

Freddy: If your not getting the Com 7 channels, and you've got an HD tuner, then logically, your tuned into a transmitter that doesn't have them.
Try checking which one your tuned into - if its Nottingham, then do a retune, perhaps manually.
If your on Waltham, then check signal strength. If your signal is low, then yes, check cables, etc.

Paul B: We dont know your postcode, so we dont know how many channels you should get, but if your only getting 37 out of 88, its likely one of two things:
1) Your tuned to the wrong transmitter - perhaps a Light one. Check that
2) If you are tuned to the main transmitter, then check signal strength (remove booster first). If its low, and your missing muxes, thats a classic sign that your system has a problem.
You say otherwise, but logivally, something must have changed at your end - remember your system is made up of 6mm thicj cable, perhaps bodged together, and subject to the weather.
Check back from the TV - each cable and connection, until you narrow down the problem, including perhaps swapping out the aerial lead for another one - a cheap way to test it.

Kenneth Johnson: Looking at your problem, you've got an issue with possibly one mux. As Steve has pointed out, if the transmitter is working OK, they logically it must be you.
Try replacing the aerial lead from the wall to the TV - they are really cheap. Loads of people complain about a similar problem, and all too often, its simply a damaged lead, which is killing a particular frequency. Give it a go, and then see what happens.
