Has the situation changed since your post?
If not, how long has the problem existed?
Whilst the transmitter has been the subject of Planned Engineering, this could be/have been the cause of your reception problem BUT I can't give any further constructive comment on that, without a full postcode to check your predicted reception.
At the time of this post Mendip COM4 transmissions appears to be normal.and there are currently no listed fault reports.

My free view comes through my Ariel. Since last Friday, I have pixelation on most channels and the volume is intermittent. I am on the Mendip transmitter. I have retuned my TV, nothing works. I read that there are engineering works on the Mendip transmitter week starting 15/4.
My neighbour has the same.
Is there a way of finding out when this engineering works finishes or has it finished. Any info would be very helpful Thankyou

Jackie Hone: Arqiva (the company who operate the transmitters) never say when the work is due to finish as it is often dependent on factors such as the weather which are beyond their control. Retuning was a bad idea as you have likely deleted all of your channels which were previously correctly tuned. You will now have to retune periodically until you get your channels back.

Jackie Hone:
A lot of main transmitters have been having extensive Planned Engineering in recent times. It's over 10 years since DSO and no doubt to ensure that the transmitters and masts continue to give reliable service for another decade such work is needed. In addition to which the Mendip mast is a similar construction to the Bilsdale mast that was destroyed by fire in August 2021, so I'd expect some of the work would be to try and ensure that fate didn't happen at Mendip.
Most of the service area is receiving normal signals, you may be in a weaker reception area BUT as you haven't given a full postcode, we can't check that or check if you might be vulnerable to mobile mast interference.
It is worth emphasising, as already mentioned by StevensOnln1, assuming you were correctly tuned, anyone should NOT retune if you have no signal or bad pixellation, whether it's due to a fault, weather conditions or engineering. You cannot tune to signals that are not there or can't be decoded.
I assume that you have checked that your aerial still looks intact and is still pointing correctly after recent severe weather, and that the downlead isn't flapping in the wind,
If you've lost your correct tuning, your best option is to clear memory of any incorrect tuning - by unplugging the aerial and doing a full automatic retune which should clear memory as no signals should be found.
Then plug the aerial back in and do a MANUAL retune for UHF channels 30, 32, 33, 34, 35, 36 and 48.
You may not receive C30, the Local multiplex, as it's beamed towards Bristol and you may not be in that reception area.
