Mendip appears to have been having engineering work continuing this week as more detailed in the 3 posts before yours (whatever Freeview advice have been saying!).
If you a re in Bristol, you are north of the transmitter and so I can say that ArqB/COM6 is currently transmitting and appears to be on normal power. I've made several checks this week and not observed any long periods of no signal or breaks but then I'm not monitoring all the time.
You mentioned in a previous post that only one of your receivers is "sensitive enough" to receive the Local mux! As I mentioned in my response to your previous post, you are either in a poor reception area, but again as you haven't given a full postcode I can't advise on that,
OR of course you have some issue with your aerial installation,
There is a 3rd possibility, and that is interference from a new/upgraded phone mast.
Have you had a postcard from RestoreTV, put your postcode into this page on their website to check
https://restoretv.uk/post…ure/
If the answer is YES, then you need a Free filter from them - it's more commonly known as a 5G / 700MHz filter.
If you post back with a full postcode, we may be able to give further advise.

Forgot to add, did you retune when you had no signal? That's never advised as it usually just clears your correct tuning, you can't tune to a signal that is not there.
Try a MANUAL Retune of C36.

I don't suppose anyone made a phone call as I'm sure they would have posted here had they read the post and were getting no ArqB signal. The fact is that ArqB (nor any other multiplex) had been off-air for any sustained period this week, there may have been very short breaks (seconds) when there's been switching to the Reserve Antenna or Reduced power which appears to have affected several multiplexes at times. It would be interesting to know what your reception of AyqA was like at this time.
Reception predictors don't work with partial postcodes, so you'll have to go and check yourself, all I can say is, that the general Locale will have many spots that will have poor reception from Mendip due to their general elevation being quite low and not having line-of-sight to Mendip and possible obstructions from other buildings etc. Transmitter operation on the Reserve Antenna will make matters worse, it being lower down the mast.
There will be many places in the Locale that apart from having clear line-of-sight to Ilchester Crescent also appear to do so for Kings Weston and Mendip!! However I'd suggest you check out the possibility of using Ilchester Crescent for more reliable reception (aerial rods vertical).
The area is of course full of mobile masts, even if you haven't had a postcard (plenty of cases where people haven't but should have) I'd be surprised if that check didn't claim a YES.
If you get the 700MHz Filter it will clobber 4G as well so you won't need both filters.
But you might also want to consider upgrading your aerial, maybe a high gain Group K log-periodic (eg. a BLA-LP56K). Whether that'll do may depend a bit on the gain of your current LP. Higher gain may be needed, but if Ilchester Crescent is an option then the BLA-LP28K or your existing LP may do.

Did you not read the post immediately before yours?
Without a full postcode we can't check your predicted reception or offer other advise.

I think you should be able to get all those by Manual tuning -
Channel S - 11538 V 22000 5/6
Iqra Bangla - 11112 H 22000 5/6
ATN Bangla - 11082 H 22000 5/6
NTV - 11464 H 22000 5/6
TV One - 11464 H 22000 5/6
Ion TV - 11538 V 22000 5/6

Stephen Potts:
Can't find any reports of faults for Sudbury at this time and it's not currently listed for Planned Engineering, nor is there any atmospheric conditions that may result in interference.
Is this the first time you've had this problem?
Has it continued or has it resolved?
Have you had a postcard from https://restoretv.uk/ ?
It's always worth giving you aerial system a checkout. Check that all your accessible coax connections/plugs are clean with no corrosion or water and properly plugged in. Check that the downlead isn't deteriorated (brittleness and cracks on the sheath). Also check that the aerial looks intact and is pointing correctly.

As there are several transmitters (some nearer) that you might receive in your locale, although Sutton Coldfield is predicted to be far the strongest, it may be worth checking in your TV's tuning section that you are tuned to the correct UHF channels for Sutton Coldfield.
All the multiplexes are C43, C46, C40, C42, C45, & C39 that's in the order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, & ArqB/COM6. (C means UHF channel).
For which TV channels - LCNs - are on which multiplex, see
Channel listings for Industry Professionals | Freeview
IF you retuned at any time when you had no signal or badly pixellated pictures you may have got tuned to another transmitter received off side-lobes of the aerial!
It's NEVER recommended to retune if you were correctly tuned when you have no signal or badly pixellated pictures - you cannot tune to a signal that's not there or can't be decoded.
You MIGHT get the Local L-BRM multiplex on C48 but I suspect it will be very variable to poor, if at all.
Could you post the Signal Strength and Quality figures for each multiplex's UHF channel which might help identify possible causes of the problem.
As detailed on the Sutton Coldfield transmitter page, it has been on Planned Engineering for several weeks which won't be helping in your situation as your local terrain doesn't give you clear line-of-sight to Sutton Coldfield, so the taller pole for your new aerial may be of some help.
I hope that was a Group K aerial that was fitted as there are a number of mobile phone masts near you which may be new or have been upgraded to use 700MHz and you could be getting interference.
I hope that installer got out his spectrum analyser to check!
You should have received a postcard - https://restoretv.uk/post…ure/
We know many cases that haven't but should have. If you haven't got a 700MHz (5G) Filter get in touch with RestoreTV to request a Free one.

It could be anything to be quite frank. As mentioned in the previous post, and umpteen times around this site, reception predictors don't work on partial postcodes. GL19 4 is a very large area with extremely variable terrain. Reception may vary from zero to quite good despite the distance.
Also we can't check if you may be susceptible to interference from a new/upgraded phone mast using 700MHz (5G/4G+). It could be you should have had a postcard from RestoreTV but haven't (we've encountered a number of such cases).
Check you are correctly tuned to Mendip's UHF channels as listed in the section at the very top of this page.
Please give the signal strength and Error figures for each UHF multiplex as well as your full postcode.
Do check some obvious things such as is your aerial looking intact and still pointing as it was, is the coax secure and not flapping in the wind? Check all accessible coax connections and ensure there's no corrosion or water. Sometimes these sort of problems can affect one multiplex without an observable effect on the others.
Do you have any amp and/or splitter maybe to feed more than one set?

Chanda:
Could you please list the particular Asian channels that you want to watch.
