The symbol shows the location of the Sandy Heath (Central Bedfordshire, England) transmitter which serves 920,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Sandy Heath (Central Bedfordshire, England) mast?

There is transmitter engineering work this week at Sandy Heath with possible weak signal from time to time.

I come back from three days away, having switched my television off at the power switch and on switching my Panasonic Smart tv back on, cannot now get BBC1 and BBC2 on channels 1 and 2 - the screen says no signal. I have done all the usual things - erasing and auto-retuning channels - but no change. I can get HD on 101 and 102, but why can't I get the standard channel for regional news &c? Why am I paying a licence fee for no standard service?

There is no fault at the transmitter so you are paying for a service you would be getting were it not for a problem with your equipment. Please check all your aerial cables and connections, unplug any coaxial plugs/sockets and refit them. Then check what programmes you get. It does not help to have retuned, all that has done is removed all the correctly tuned channels you wanted. You will need to check that each of the multoplexes broadcast from the Sandy Heath transmitter are being received correctly and at what signal strength. The multiplexes are on channels 24, 21, 27, 51, 35, 48, 55 and 56.
As you have not given a full post code, as requested, we cannot check the reception conditions at your location.

Hi, We have been experiencing loss of picture and or sound for the past month at 7pm to 7.30pm every day without fail, does'nt matter what channel, always same time. I have retuned TV and dig recorder , both show 100 % reception. Is there a reason for this regarding s/heath transmitter? Our aerial is sited near roof and our post code is mk64hq.
Please advise.
Many thanks,
Nigel.

Retuning was the worst thing you could do as it will never solve the problem you report.
You need to investigate what equipment comes on and goers off at the times stated. Also ask your neighbours who also use Freeview if they have the same problem. If they don't then the source is likely to be in your property.

Nigel. reception should be very good at your location. (see coverage checker) I think if all channels are knocked out it suggests very strong nearby interference . Could be tricky to sort out . Possibly an anti phone signal filter might fix it . But it could be you are very near a phone mast . However check with neighbours to see if they get the same problem . If they don't then I would check your aerial system . You may even need a small attenuator in the aerial lead if the signal is too strong .

As has already been said, this sounds like a problem with interference. It's unclear from your post if it just "starts" at some point between 7pm and 7.30pm, or is present for exactly that period only. Whichever, it's clearly a regular event probably on a timer. The most common things are central heating, hot-water heating (Immersion heaters) etc. Igniters or thermostats may have gone faulty, but external flood lighting is another possibility, nor should you rule out any internal lighting such as fluorescents (compact or otherwise) and I'm afraid some LEDs (non-filamentary types which are the most common) all of which may have developed a fault.
Check the timing of your own electrical equipment, and also see if neighbours are having similar issues. It could be a near neighbour that has the faulty equipment.

Celine . It is unusual to loose standard signals yet have HD ok. I suspect that your tv is partially tuned to the wrong transmitter . This can happen if youre near several transmitters . The auto tuning might pick the wrong one . You may need to do a manual tune on the UHF channels listed by Mike .
