Those two channels are on different multiplexes so it's not necessarily a problem with a multiplex, see Channel listings for Industry Professionals | Freeview for which channels are on which multiplex.
I assume that you have some sort of splitter to feed 3 televisions, is it an splitter/amplifier?
Your problem suggests several possibilities -
1) Check all connections between the splitter and the set including any flyleads
2) The signal output where the JVC is being used is not as strong, try the JVC in one of the other locations.
If that's no different -
3) The signal your aerial is receiving may not be very strong/is marginal - a full postcode would be needed to look at your predicted reception - and the JVC is not as sensitive as the others
If the JVC gets the signals in one of the other locations -
4) The splitter is not giving a good a signal on the normal JVC location output, try swapping the outputs at the splitter it with one of the others.
If that solves the problem, the splitter could be faulty.
If that doesn't make any difference -
5) The cable run to the JVC location is much longer and has higher losses or the cable has a fault. Try one of the other televisions at that location.
If all those checks doesn't solve the problem, post back with a full postcode and more detail about the aerial installation and splitter etc.

This isn't the broadcaster's website (it's an independent help site) so they are unlikely to see your comment.

The fact that you were only receiving 40 channels instead of the usual 128-140 is probably down to some "Tropospheric Ducting" which is occurring at present - see Effect of tropospheric ducting on Freeview | RTIS for a simplified explanation.
There currently aren't any reported transmitter faults or engineering at Caradon Hill.
Do NOT retune when you have loss or breakup of signal (whatever the cause) as this usually clears correct tuning, and when there is "tropo" you may get tuned to a distant transmitter in Europe, Eire or the UK.
This doesn't always affect all multiplexes and can come and go over seconds, minutes or hours. Unfortunately it was predicted to be quite strong over parts of Devon and Cornwall and may cause further disruption over the next couple of days. It should settle down and have cleared by Wednesday.

Apologies that we seem to have missed your post a week ago. NO it is NOT 4G Interference which as you mention is the 800MHz band. There are no TV transmissions near the 800MHz band which was cleared some years ago. The 700Mhz band which has recently been cleared for future 5G transmissions hasn't been sold yet so that is not going to have any effects. Unless you have a mobile mast VERY close to you, you are unlikely to have any problems with interference in any event whether it be 800 or 700 MHz.
Sutton Coldfield is currently listed for Planned Engineering with the most likely outcome being "Possible weak signal", but experience says that there could also be brief interruptions.
As has been mentioned before, advice is Do NOT retune when you have loss or breakup of signal (whatever the cause) as this usually just clears correct tuning and you'll have to retune again later when signals return (to normal).

As you say the Local Brighton mux L-BTN is on C40. The site owner hasn't had time to do all the updates resulting from the 700MHz clearance, and the regular posters here periodically make a post with the updated listings. Thanks for yours, my last one for Whitehawk Hill was on the 25th July on p91.

The Salisbury DAB transmitter currently only transmits the BBC and D1 multiplexes. On some pages on this site coverage may be shown if you haven't got "Pro" mode selected, but there are many cases where I'm not convinced they are working correctly. I know some transmitter pages actually show the transmitter at the wrong location on the map!
Whilst a "small scale" DAB multiplex is proposed for the Salisbury transmitter, applications to OFCOM only closed on the 23rd November and no announcements have been made.
Watch this page Radio broadcasting updates - Ofcom for updates.
In general, checking coverage is probably best achieved by using the postcode checkers at
ukdigitalradio: Home or Postcode checker - Digital Radio UK
A lot of technical information can be found at DAB Ensembles Worldwide | Latest News & Updates
Some of the detailed UK pages have links to maps from Arqiva.
You may find useful info at Digital Radio (DAB)
Ian selmes:
CORRECTION. I haven't a clue why I posted that R5Live is not available on DAB - it IS on the BBC Multiplex 12B.

For this independent help-site to provide the best help, a full postcode is normally required to look at predicted reception at your location. However, the Faversham transmitter has recently been on Planned Engineering where you may have had Weak signal or Service interruptions.
You are always best advised NOT to retune when you have No Signal messages or pixellated pictures, are more often than not this just clears correct tuning and you have to retune when signals return to normal.
Some sets do automatic retunes which can be a real nuisance in circumstances where signals are lost, you are best advised to find the setting in your TV's tuning sections and turn it off. You should only need to retune when you see an on-screen message to do so. These days that should be a very rare event.
If you manually retuned when you lost signal, try retuning again.

Apart from seeing my post in reply to you on the Faversham page Faversham (Kent, England) Freeview Light transmitter | free and easy there has been some "Tropospheric Ducting" around with the recent high pressure affecting some parts of the country at varying times (it can occur in winter). If it's continuing to affect you, it should clear by Wednesday and things should be back to normal.

As per the post immediately before yours here (now on p15) COM7 has not closed and the post before yours refers to a previous post with details about what happened to COM8 and what is happening to COM7. Please read the linked posts. Information on various transmitter pages on this site is incorrect not just about COM7 but it hasn't been updated in many places with all the 700 MHz Clearance changes.
Ridge Hill has had no reported faults recently and not had any listed Planned Engineering.
There has however been some recent "Tropospheric Ducting", see Effect of tropospheric ducting on Freeview | RTIS for a simplistic explanation. This can affect reception of any multiplex, and not necessarily all, or at the same time, the disruption can last for seconds, minutes, or hours. The interference can come from other transmitters, in Europe, Eire or the UK.
The effects will likely be worse if the normal signals aren't very strong. COM7 is transmitted as an SFN and at lower power than the other multiplexes and to complicate matters with SFNs there can sometimes be some "not spots" where signals are much weaker or can't be received. As you haven't provided a full postcode, I can't advise what your typical predicted reception of COM7 (or other multiplexes) might be.
Depending on your location within the Ridge Hill coverage area, COM7 signals could be affected by eg. signals from Mendip, Wenvoe or Sutton Coldfield, the latter currently having Planned Engineering with "Possible weak signal"
If you've retuned, or your set automatically retunes when you had no signal or badly pixellated reception, this can usually just clear the correct tuning and you'd need to retune again when signals return to normal. It's advised to turn off automatic retuning, it's often more trouble than it's worth, and these days, retuning should be a less frequent occurrence and you'd be advised if one was needed by on-screen pop-ups.
If you have retuned and still don't have COM7, I would try a manual retune of C55 after Wednesday evening when any effects of the Tropospheric Ducting should have subsided. If this doesn't work, post back with a full postcode so we can look at your predicted reception.

Whilst there are quite a few printed TV magazines/guides, as I don't buy any, I don't whether any might have DMAX. However, there are many on-line listings which do, and a number of them where you can customise the format of the guide to your taste.
Freeview's own guide (not brilliant IMHO) has all LCNs (except the Adult section) TV Guide | Freeview and many others online have similar, but not necessarily all when in a printed version.
Just do a search for TV Listings and you'll come up with many, eg. -
TV Guide - Radio Times UK TV Guide & Listings - Radio Times
The next two are customisable
TV Guide & Listings | What's on TV
TV Guide - TVguide.co.uk
That last one hasn't updated the LCNs since Freeview's shift of all those from 24-54 up one!
