I have now lost all signal can you tell me what the problem might be?
Brian Butterworth published on UK Free TV The problem could be one of:
- the aerial has been moved or damaged;
- the cables or connectors that connect the digibox to the aerial are damaged;
- the digibox has broken.
If you have a "spare" digibox you use this to test the aerial connection. Can you still watch analogue TV OK?

Myra: No one can possibly offer advice on problems of this nature without having prior knowledge of the system being referred to, insomuch is your reception via a satellite dish as used by Sky or Freesat? or alternatively Freeview via a normal aerial?
A post code being required if its the latter, as this enables access to details of the transmitter covering the area you happen to reside in.

Myra: DUK's coverage checker indicates your area as being served by either the Sutton Coldfield transmitter @ 61miles / 120 degrees, or The Wrekin @ 35miles / 140 degrees.
However, a terrain check on your location relative to that of both stations has revealed that the signal path from both Sutton Coldfield and The Wrekin transmitters suffers from line-of-sight blockages starting from approx 1 mile prior to the area you reside in, line-of-sight blockages always having a much greater effect on reception if the obstruction is located at only a relatively short distance away from the receiving aerial, any signal that is received being via diffraction (signal bending) likewise vulnerable to being affected by weather conditions / slight atmospheric changes etc and which I feel is the reason for your problem.
That said, although the signal might well have vanished from your screen its not necessarily the case that the signal doesn't exist, as its possibly just dropped under the threshold level necessary to resolve a picture, something which you can test for yourself using the following procedure provided that your Freeview TV or box has a manual tuning facility.
The procedure being: When the signal vanishes go into your TV or boxes tuning menu and select "manual tune",
then "if" your reception is from Sutton Coldfield enter 43 (BBC) into the box (if The Wrekin 26) but "stop" at this point, (do not press search or tune) because if any signal is being received the level of will appear in the strength / quality indicator bars no matter how low it might be. The point of the test being, that if you do get an indication of strength "and" quality (essential) then it might be possible to recover the picture with the aid of a variable powered booster.
By the way, have you ascertained if others in your area suffer from similar problems with reception?

Freeview has gone completely, tried re-tuning and it's not working. There is no 'Factory Restore' setting or similar in the menu. My postcode is G5 0QJ

J: P/code indications would suggest that you are connected into a communal aerial system, if you are? then you should check with someone else who resides in the block to find out if they are also experiencing problems with reception, as a fault could have developed on the distribution amplifier system.
The other point to remember being, that as you have already tried retuning your TV or box and not received any signal, then the retuning action when no signal is present will have deleted all channels stored in your TV or boxes tuner, frequent retunes now being required to recover same otherwise you will be unaware when/if the fault has been rectified.
That said being on the basis of you having checked the jumper lead coupling your tv into the wall plate outlet socket, and that you are on a communal aerial system.

Everyday day between 7pm and 9pm I completely lose all signals and have no service at all until about 9am next morning when everything seemingly automatically retuned and is fine until 7pm. What is happening? How can I correct it? I have a digital tv a roof arial and a PVR connected up. I live in N London, N11 and am getting desperate.

Gilli Pettinger: Search for single source interference on this site.

Gilli Pettinger: This type of problem can be caused by a number of reasons, such as the signal being wiped out by severe localised interference emanating from equipment being used by a neighbour, although this is not so likely to apply if your place of residence is separated from your neighbours, i.e: not through a wall.
Apart from that, if the aerial input socket on your TV is fed via the PVR's in / out sockets, the next time the signal goes off try connecting the aerial directly into the TV.
Another thing to try, is selecting say ITV1 on your TV and also the PVR, switching between the two receiving sources when the signal vanishes using the "input select" (or source) button on the TV's remote control.
This test is only to verify that the signal has actually vanished, and that the problem is not being caused by the actual TV or PVR.
Maybe you could also clarify regarding the following. Is your roof aerial exclusively for your own use? and if it is, is any form of powered distribution amplifier being used?
Further advice dependant on feedback.
