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.

I live in Sutton Coldfield, Have a clear view of transmitter from bedroom window, no obstructions whatever. Philex High Gain aerial in loft, digital coax cable throughout, digital aerial socket outlet used. Sony Bravia TV, Sony Hard Disk Drive Recorder the aerial goes into recorder & out to TV. Have been careful with installation, still get pixilation on every channel. Have fully rescanned TV & recorder. Can you help please?

Alan White: Due to your location, the problem could possibly be caused by the tuners in your Sony devices reacting in an adverse way to being overloaded by an excessively high signal level being fed into them.

To get an idea if this is likely to apply or not, remove the aerial connector going into the TV (from hard disc) and temporarily replace it with a short length of wire inserted into the middle of the TV's aerial socket (e.g: about 4 feet of lighting flex) and check what the signal is like.

Alan White : Another method of temporarily reducing the signal strength, but in a less drastic fashion, is by turning the aerial by exactly 180 degrees whereby giving a reverse pick up.

jb38: I'm not surprised at Alan having pixallation - I've got a Sony PVR and they have very good tuners. Yes, they are far more robust than perhaps Panasonic or Humax, but they do pull in a signal! I live in North Cambridgeshire, but my RDX-895 gets Waltham, Belmont, Talcneston (just enough to annoy) and Sandy Heath (ditto). I've killed

Alan - your going to need some attentuators!

MikeB: Yes, quite so, as signal overload is indeed the most likely reason for Alan's problem, although the signal level received from the aerial in the loft mustn't be quite as high as what would normally be expected from transmitters/tv/Sutton_Coldfield">Sutton Coldfield's 200Kw transmitters, that is, going by the fact that Alan's reception has not been completely wiped out.

However, an attenuator such as the one seen on the undermentioned link is likely to be the answer, albeit that I have reservations about recommending these sort of low cost variable devices and much prefer fixed types, however, variable types do seem to be popular even although they are somewhat critical to adjust.

jb38: I must admit that the variable attenuator I bought really didn't seem to do much. I bought some cheap fixed ones from Amazon for less than ?2 each, and the 12db works very well. The advantage with a number of different fixed ones is that you can put them in series if need be.

Remember that the Sony's tuners are pretty robust. My PVR was on 95% signal strength with only an occassional blip on BBC channels, which would have wiped out a Panasonic, for example, so it might be just on the tipping point.

Hi I have a DREAMAX Freeview digibox, which has worked relatively fine until the latest update,
which was about three weeks ago.
Now, almost everytime when I go to a high number channel such as 130 or 132 the channel order is thrown out of
out of sequence, so that below and above 132 the channel numbers are random and a message
"new services are being installed" pops up. The only way to reset the channel order seems to be to go
to channel 1 and from there back to 130 or 132 and only then the epg guide shows the channels back in
order. Also if you go to say channel 11 instead of 1 a message pops up "invalid entry".
Any ideas would be much appreciated.
