Problem posted earlier on the site was subsequently sent to HUMAX
For several months now, probably started around time of the introduction of ITV-X, the EPG has consistently shown 'no-programs'

I have tried all possible option and suggestions given by others to rectify the problem, to no avail
I have gained from Internet searches knowledge that on the model 5000T there is a EPG reset option, I can find no similar option on the 'settings' menu on my 4000T.

Is there a solution to the problem that doesn't need the complete loss of all saved programs?

Humas response
Since the device has a lot of channels available on it, the signal gets divided which results in the EPG (program guide information) not populating like usual.
However, there is an easy fix for this which is to delete some unused channels on your device.
Please follow the steps below to delete your unused channels successfully:
Press the Freeview play button > Settings > Channel settings > Edit channel list > delete unused channels from the channel list (once you click OK on a channel you don't want to have, press the + button on the remote and you will get the option to DELETE the channel).
By deleting your unused channels, the signal will become better for the ones that you do use, which should result in the EPG populating once again.

Result of the above
I got as far as Channel settings; the only option available was 'signal test' all other options were 'greyed out' and so unavailable.

Is there a 'plan B' available?

Humas response

If the other options are still greyed out, please try a Power Cycle on your device to see if there's any difference afterward:
Power OFF your device and unplug the POWER CABLE. Allow for about 15 minutes.
Plug the POWER CABLE back IN and Power ON your device.
After the Power Cycle, please follow the steps in the previous email to delete your unused channels once again.

Tried this..................SUCCESS!

A big thanks to all who responded to my original enquiry. I post the result of the Humax information in case there are others having problems with the EPG.

Bruce:

Thanks for that info Bruce.
I'm somewhat sceptical about the "signal gets divided" explanation/excuse, it's sounds more like the memory can't cope/gets itself confused with all the available channels these days, after all it's an older model.

However, the important point is that by doing that procedure, the issue was fixed.
It'll be interesting to see if the problem returns next time you do a retune and get all the channel installed again.
If so, you'll unfortunately just have to repeat the procedure, but do let us know how it goes in future.
Thanks.

During the early part of October I experienced picture tearing on all Channels received from the Mendip Transmitter. During the latter part of October the reception returned to good. Since then the reception has returned to tearing. As I receive the signal propagation across the Bristol Channel, Is the signal being effected by high/ low pressure, exceptional high/low tides and/or has the ERP from the site been reduced? It may be that I am also receiving at my high gain Yagi aerial a reflected signal which is reducing the signal received. Do I need to replace the aerial with a Yagi that attenuates the reflected signal. The aerial is in my loft of a three story house that from the top floor has a view of the Bristol Channel.

ROGER F C ALBAN:

It's likely to be a combination of factors I'm afraid. There's been ongoing engineering at Mendip, see post(s) before yours, on and off for some time, and the effects on signals will not always be the same depending on the work at any given time, eg. whether they are on reduced power or using the Reserve antenna - details are never given!
There has recently been some tropospheric & temperature inversion conditions which high pressure can sometimes give and this could be quite variable over the coming few days.
Tides and water levels can sometimes also cause quite a variation in signals.

Also, given your general location you could also get interference from some of the Devon (and maybe elsewhere) transmitters from time to time in certain conditions. For example Huntshaw Cross uses the same UHF channels for its COM muxes as Mendip for it's PSBs.
Using aerial with narrow beam widths might help, but even then there will be no guarantees. Unless you are someone who is prepared to experiment a bit with aerials, you are probably stuck with the situation as it is.
Hopefully the engineering work will be completed soon and things will settle down!

Just to add to my comment about aerials, smaller side lobes may be equally or even more important than beam width. As mentioned it's a case of experimenting if you wish. Changing the direction of the antenna may even help, on the other hand it could make things worse!!

All freeview channels gone on two tvs. Received filter from restore tv and still nothing. Have rescanned, unplugged rescanned again and the rescanned when plugged back in, nothing happening. Signal checker says full signal with booster but tv says no signal. Freeview says no engineering on mendip transmitter but restoretv says there is. Help!

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
