The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 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 Oxford (Oxfordshire, England) mast?

Steve Donaldson: Thank you I was aware of Seagry Court etc. We prefer the BBC South news, and Seagry Court does not carry LOX which also carries a couple of channels we occasionally watch. I suspect it is a failed amplifier as the BBC1 signal from Seagry Court received on the side of the aerial, which was in the 800s is also absent.

A check just now shows the BBC have not reported any faults for the Oxford transmitter. I find it highly unlikely that if the transmitter had been down there wouldn't have been several reports, not only here and a few other places, but certainly direct to the BBC.
I'm afraid a few reports solely on "isitdown" are no reliable indicator of a transmitter fault,.Considering the weather we've just had (and based on previous experience) may reports will be due to problems with their own systems, a number will be with aerials now pointing at the pole star!
If you have a masthead amp and think it could be faulty, do check that it's still receiving power initially checking the power unit. I'm afraid the only other check of it will involve someone getting up there. Do you perhaps have another aerial (even set top) you could try checking signals from Seagry Court as you are only 2km from it.
Do not ignore the possibility that if a new/upgraded phone mast has just started up on 700MHz it could be saturating your masthead amp. There's at least 10 mobile masts within 1.5km of you, so who knows. This might block all other signals at the set which could also have an overloaded front end. In your TV's tuning section, do any signal strength and quality figures for any of the UHF channels show up?
If accessing your aerial and masthead amp is something you do yourself, then you could get Restore TV to send you the external filter, otherwise they'd need to fit it.
Ideally these days a Group K aerial is also best.

Sorry, also meant to ask, you mentioned your "next door" app, were those with problems your immediate neighbours?
Or were those reports from people further afield? Considering the locale and terrain between the area and the transmitter those further afield may have much poorer predicted reception from Oxford.

Chris.SE: having now checked the signal strength and quality I find I get a full 10 on the signal strength and 0 quality , except channel 7 and the other LOX channels where I get 60 to 75 percent, the same I get for LOX normally, but quality is still zero. I tried putting up to 18db attenuation at the set end, and that made no difference apart from the strength was reduced.
This would suggest it is the amplifier not the tv fronted, though the LOX result confuses me as I would have expected if the amplifier was overloaded it would not matter what the received signal strength was from the transmitter.
The people who responded on 'next door' live not to far away, but no immediate neighbours as many of those we know to speak to are on Virgin.
I hopefully have an aerial man coming out tomorrow who no doubt will charge an arm and a leg, but if it is not 700mhz interferance the amplifier must be oscillating or doing something silly.

Well good luck with that then, yes the amp could be doing silly things like oscillating.
I hope he's got a spectrum analyser.

Chris.SE: sorry meant to come back. Despite my quick check on the power supply for the amplifier which said it was OK, when the aerial company who attended, first one kept rescheduling, looked with a spectrum analyser it was doing something odd. New psu and everything OK.

Thanks for updating us on the outcome. A process of elimination had at least pointed the finger in a suitable direction and final diagnosis would have been tricky without specialist equipment other than by equipment substitution. Remote diagnosis is often difficult.
I hope the aerial man didn't charge a huge arm and leg!
