We have had bad pixelated tv for two days now. How long will this be for? As unable to watch it as it is?

Pixilation on bbc1 for 2 days making it impossible to watch. Is this a problem you are working on?

I don't know if HD is working again this am/27th
[Data on Sandy Heath seems inconsistant the map had not listed Sandy Heath as having issues
Transmitters | free and easy for 21 years
]
I'm incredulous Sandy Heath do not provide more detail on when (day+time)services will be impacted, so that customers can rule out other causes (like 5g) if they have issues.
Their weekly pixelation+flickering messages have been running for months.
I had already checked the restoretv link post-code checker and had no messages about 5g

I'm based near Hertford and our freeview signal comes from Sandy Heath (no idea why!). The HD channels have been unwatchable since last week.
Did some digging over the weekend and found that all channels broadcast on MUX BBCB/ Ch21+ have the problem. Signal Power and Signal Quality are both 100% on this channel.
There is obviously a problem, but the general lack of information around the issue and timeframe to fix is unacceptable.
Given the message here, maybe everyone using Sandy Heath has this problem.

paul : And others
As you can see the BBC report says -
From 8:27am to 9:15am on 27th Nov 2023 BBC B HD Poor quality due to a fault
NOTE - 8.27 to 9.15am on 27th Nov 2023 - That's TODAY. There was no report there yesterday, it's one of the places I regularly check to see if the BBC have made any reports.

It certainly seems that it was a widespread issue judging by the information now available. I am rather surprised that the BBC were that slow in identifying it as a fault rather than anything due to the planned engineering, especially as it's a main transmitter and all the monitoring that they have.
Perhaps it was just a bad day!
You mention that you don't know why your signal comes from Sandy Heath. If you provide a full postcode, we can check your predicted reception to see which transmitters (if more than one) you may get and which may give you the best reception.

Unfortunately, as I've posted quite a few times before, and it's very frustrating on a number of occasions for many -
Arqiva, who are the company responsible for the great majority if transmitters in the UK, never give any details of what the work entails or how long it will last especially as some of it may be weather dependent which means delays can happen as you can't climb masts, service antennae, cables, guy ropes, etc when weather is unsuitable.
Just also worth noting, that it's a good 10 years since DSO and many transmitters will have needed extensive maintenance etc to ensure they continue to provide reliable transmission during the worst of the weather conditions we may see, etc.
Sandy Heath has had Planned Engineering for several weeks now, one assumes that quite a lot of maintenance and possible repair work has been needed.
Having said that, most of the main transmitters in the UK have had extended periods of Planned Engineering this year.

I can't pick up 5Action anymore, and some other channels. I'm based in Cranfield, Bedfordshire. Does anyone know what's going on?

Giovanni Maiello:
The transmitter isn't currently listed for Planned Engineering and I can't find any currently listed faults but 5Action is on the SDN multiplex and finding fault reports from COM multiplexes can be like getting blood from a stone!
How long have you had the problem?
Are the other missing channels also on the SDN/COM4 multiplex?
For which TV Channels are carried on which multiplex, see
Channel listings for Industry Professionals | Freeview
As you haven't given a full postcode, we can't check your predicted reception for the SDN or other multiplexes, or whether you might be vulnerable to interference from a new/upgraded mobile mast now using 700MHz, if so you could be entitled to a free Filter.
Do check in your TV Tuning section that you are correctly tuned to Sandy Heath's UHF channels, as you may receive other weaker signals from another transmitter which often disappear as the weather changes.
They are C27, C24, C21, C33, C36, & C48 that's in multiplex order -
BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6
If you can normally get the Local multiplex from Madingley, it's on C35.
If you provide a full postcode, we should be able to advise further.
