My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+
published on UK Free TV

To deal with the problem you must clear the channel list completely and then rescan - if your box has it in the menus, please the 'installation menu' to do an initial scan or a reset to factory settings or First Time Installation. You MUST delete the entire existing list of channels. On most boxes this technique can be also be used:

Try this:

1) unplug your Freeview box (or idTV) from the mains;



2) unplug the aerial from the Freeview box by disconnecting the cable from the 'RF in' socket;



3) wait 30 seconds;

4) plug Freeview box (or idTV) mains back in;



5) do a complete scan for channels - it will fail without the aerial. (This may be in the installation or initialization menu, and is distinct from any 'add channels option'). Once this is done your channel line up should be empty;



6) reinsert aerial by reconnecting to the 'RF in' connection;



7) do a complete scan for channels again.



The Freeview channel line-up provided by six "multiplexes" - each of which carry five or more TV channels, radio channels, text services and EPG data. In this diagram each ROW represents a multiplex. If you are still missing a whole multiplex (ie everything on the row) you may need to replace your aerial with a wideband type, purchase a larger aerial or you may have interference from a VCR, games console, Sky Digibox or similar.

Regarding the post above, I receive transmissions from the Heathfield transmitter.

Trevor Carpenter: Good morning, Trevor. The Heathfield transmitter does not have any issues or engineering work on it today. The following advice, however, is given on the Digital UK website today: "Latest News: Viewers in some parts of the UK may experience temporary disruption to their TV signal today due to high atmospheric pressure. We advise that you do not retune - reception will return to normal once this weather system passes." Hope this helps. Obviously, if you have done a retune already, your equipment will have lost the channels stored in it before you did so,and therefore, another retune will be required. It is important, however, not to carry out another retune until the high pressure system has dissipated, otherwise, if your receiver picks up and stores signals, it will probably pick them up from somewhere else, other than Heathfield, and you do not want this to happen, so please wait patiently until you know the atmospheric pressure has lowered before you retune again.

phill gethins: the PSB1 multiplex at The Wrekin, Bromsgrove and Larkstoke transmitters has been reconfigured to facilitate the transmission of BBC Radio Shropshire on Freeview. Whilst many tuners will automatically update to accommodate the changes some need to have a retune performed to achieve this. It might be necessary with some models to perform a factory reset (or return to shipping conditions) to remove all trace of the old PSB1 data before carrying out a retune to avoid the new data being overlooked. If PSB1 is still missing afterwards I can only suggest performing a manual tune on C26 to restore it in the tuner's memory.

I live in SO45 5QU and have little or no reception of BBC News HD, BBC FOUR HD, several other HD channels, 5USA+1 and TalkingPicturesTV. It is possible that these are on the same multiplex.

A couple of months ago I cleared the channel list and rescanned. All of the missing channels were then present. Gradually, over the past couple of weeks, all have become too weak to view.

I use an internal aerial and this has proved to be more than capable of very good reception right across Freeview.
Is there an explanation as to why I can't view these channels?

John H: If nothing has changed (and it shouldn't have done at the transmitter end), but the signal is getting weaker, check your system. Dodgy fly lead would be a good guess. I'm surprised your getting a good signal with an indoor aerial, but check what the signal level actually is on all muxes - the muxes in question tend to be the weakest, so they are the canary in the coalmine. If they are all low, follow the signal path from the back of the TV upwards, to isolate the problem.

Hi Mike,
To be honest I would expect to receive a fine reception using an indoor aerial. This is what was promised when we all went 'didgy' back in 2012. As to the bits you refer to - apologies, but I don't know what you're taking about. I don't know which lead is the 'fly lead' and I've no idea what a 'mux' is. My guess is that this is industry-speak for 'multiplex'. Would I be able to find a list of the actual multiplexes in the Rowridge transmitter?

John H: Hi, John. An Aerial Flylead is used to connect from a TV aerial socket on the wall to an aerial input socket on a TV or set-top box. They are also used to connect set-top boxes and recorders to TV sets. These will have a male aerial plug at each end. A 'mux' is indeed an abbreviation of 'multiplex'. You can find lots and lots of information about the multiplexes available from Rowridge on this very website: I will copy and paste the link to that right here for you:

Which Freeview channels does the Rowridge transmitter broadcast?

Simply copy and paste this link into the URL or address bar of your internet browser and then scroll down below the coverage map to find the information about the multiplexes. Any more questions, do not hesitate to post them! Richard, Norwich, Weds. 15th. June, 10:30 a.m.

Thanks Richard,

The link you gave me has pin-pointed the 'mux' in question - "com7". All stations on that multiplex have become too weak to be seen. Would you know why that is? Would there be a way for this to be improved for me?

Cheers - John H

Hi again Richard,

One other mux is weak as well - "LSO". It looks like the strength of the signal is related to the wattage. The standard looks like 200,000W. The two I have issues with are 24,400W and 10,000W respectively.

Cheers - John H

John H: Hi, again, John. Both COM 7 and your local tv station multiplex which includes That's Solent' in your case are indeed transmitted at lower power than the other muxes and indeed, this is usually the case for the full Freeview transmitters around the country. You are, of course, perfectly correct when you say signal is related to the transmitter output power. I had the same issue as you using the full Freeview transmitter called 'Tacolneston' which is only 8 miles from here as the crow flies. What I did was to install a signal amplifier (often called a 'booster'). This worked for me, but I should tell you that there are many correspondents out there that will also tell you that "boosters are no good for Freeview'. The only warning I feel that I can give you is that it is possible to supply your equipment with "too much signal", which can cause the receiver electronics to 'crash' like a computer can crash, and if this happens, the picture will freeze and the sound will mute. You will then find that to re-boot your equipment, you would have to remove any booster altogether, then switch the receiver off AT THE MAINS SOCKET (putting it on standby won't work once it has 'crashed'), wait 5 minutes and then switch your receiver on again. Whether you try a signal amplifier is entirely your choice. I believe I've given you all the necessary warnings. By the way, you didn't say if you're using a set top box or a Freeview HD television receiver: I am assuming you are using the latter, but what I've said above applies regardless of which you're using! Richard, Norwich. PS Let me know how you get on. Suggest you Google 'Maxview' for a booster!
