C25 is the SDN/COM4 multiplex and is transmitted at the same power as the ArqA/COM5 and ArqB/COM6 multiplexes. These are the same power as the main PSB multiplexes if using vertical polarisation (200kW) but they are only 50kW in horizontal polarisation.
The Planned Engineering should have been completed and I can't find any faults reported.
There's also the possibility that you may be in a location where that multiplex is not predicted to be received as well as the others but we'd need a full postcode to check that, as well whether your aerial rods (or squashed Xs) are vertical or horizontal.
What signal strength and quality figures have you got for all the other multiplexes?
How long has this problem been happening, is it very recent, ie the last day or two? Or has it been a problem since the new LG, and how long is that? An LG set shouldn't specifically be a cause.
Have you changed anything else around in your installation? Check all your coax plugs and connections for corrosion, bad connections etc. Make sure you haven't got any HDMI leads running close to your aerial or flyleads as HDMI has been know to cause interference.

I'm in PO168UD and on Freeview can't receive channels 7, 49, 51, 60 or 94, which are all on the LOC Mux. Would there be a reason for this? The message displayed is " The receiver is not receiving a signal or the signal is too weak"

Are the rods (or squashed Xs) on your aerial horizontal or vertical? Rowridge has both polarisations for the 6 main multiplexes, but only horizontal for COM7 and the Local Multiplex.
If the rods are horizontal, you should have no problem receiving the Local multiplex - UHF C37.
I can't find any faults currently or recently listed and there is no Planned Engineering listed.
I would check that your aerial seems intact and pointing in the correct direction and that your downlead looks undamaged (especially if it is old).
Also check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them.
See what signal strengths and quality you are getting for the multiplexes (groups of channels) shown in your TV's tuning section, that information may indicate issues with your aerial or downlead or possibly any distribution amp/splitter you may have.
Problematic connections, water ingress etc. can seem to affect reception of just [b]an individual[/b] or several multiplexes.
Have you changed anything in your setup at all?
Make sure you don't have any HDMI leads near unscreened/poorly screened flyleads/aerial leads especially if those aren't double screened coax as HDMI has been known to cause interference.

Thanks, the rods were horizontal. The loft is in the roof. Picture quality on all other channels is fine, it's just those mentioned I can't view. I rotated the aerial so they are vertical, but it made no difference to the issue. The download runs in the cavity, so a visual inspection is very difficult.
As far as signal strength goes, I have an old Humax box. Going into the settings I get a display for signal strength and quality, but only for Channels 21,22,24,25,27,28 and 37. Strength for those is around 30% and quality 100%. I can't change those channels...

Hi - I'm in the M33 area - the service on the LOC transmitter seems to be off or on for the last few weeks. All other MUX are high quality - I can actually see Winter Hill TX from my roof on a clear day .
I am offered regions North West , of Isle of Man - both show the same channels.
Looking at signal status shows zero for channel 49.
Generally I have 148 channels - when I am having problems - I loose 6 channels the ones on the LOC MUX.
My arial does not appear to have moved - looks in good order.
Are the LOC MPX retransmitted on the Winter Hill transmitter?
Is this a known problem - are the channels available on line so that I could cast to my chrome

Chris.SE: I've now checked on the Freeview site which channels I should be able to receive, and discovered none of the ones I asked about are available to me! Obviously I should have checked that site before raising my question here.

The Rowridge Local mux is certainly available in parts of your postcode. The figures are definitely green - 84 Served and 99 Marginal, so that's pretty good. The aerial needs to be horizontal for the Local mux and COM7.
Loft installation will reduce signal a bit, but 30% for the main muxes is a bit low, unless your signal is coming through a party wall in the loft or a metal tank etc. it ought to be better.
I'll look into the signal variation across the postcode and post again later.

Considering the general M33 area, as you are getting your signals from the Winter Hill transmitter, there is the Manchester GI mux transmitted on UHF C27 and the Local Manchester mux on C27 - the one you're having a problem with.
If you look in your TV tuning section, what Signal Strength and Quality (or BER - bit error rate) do you normal have on C27?
Current weather conditions (again!) - Tropospheric Ducting - may be causing some disruption to signals. If you have lost tuning for C27 altogether, try a Manual tune on C27. I would not advise a full/automatic retune with current conditions.
Some of the channels are available on-line, I'm not certain which ones, you'll just have to search for a particular one.

Having looked into this in more detail, it's because the coverage checker says the most likely transmitter is Rowridge VP (vertical polarisation) so when you use the Channel Checker instead of the Detailed Coverage Checker you don't get COM7 or the Local mux, so only120 channels.
When using the Detailed Coverage Checker, if you use Horizontal Polarisation you get the lot, BUT low house numbers in the postcode (primarily those below 20) are predicted variable reception on the COM & Local muxes.
In your 5.05 PM post where you are listing the UHF channels you include C37 which is the Local mux, so you are getting it (note - the list at the top of this page is out of date).
No sign of C55 in your list (COM7). How old is you aerial? If it's quite old (pre-DSO 2012/13) it could be a Group A aerial - the original group for Rowridge - so it's not designed for C55 - does it have a Red plug in either end?
You could try a manual tune of C55 but if it's a Group A aerial I doubt you'll get it especially as the strength for the other main muxes is 30%.
Now before you even think about rushing to change it, don't. COM7 was ever only a temporary mux and is due to close by the 30th June 2022 under the current licence.
However, as I've already mentioned 30% is quite low. How many rods on the aerial (those in front of the dipole - where the coax goes)? I don't suppose you know what make/model the aerial is?
Is the aerial pointing correctly - it should be compass bearing 212 degrees for you (that's roughly 13 degrees S of SW). A slight amount either way can sometimes improve the signal.
