Hello, ;-) I no longer receive the Multiplex R4, I am served by the transmitter of MAYET (72)
What can I do?
What is the frequency of R4 to try the manual search?

Hello,
It turns out that the R4 multiplex is broadcasted by the Mayet transmitter on channel 59, a high-frequency channel and therefore more difficult to receive with some antennas, especially older ones that were not designed for this frequency. It only takes a few other factors adversely affecting reception to cause the signal to drop:
Start by checking the coaxial connections, unplugging and re-plugging them several times to eliminate oxidation; if necessary, redo them properly, and be careful, the slightest "hair" from the braid touching the copper core can mess things up...
HD TNT is more demanding in terms of both quantity and quality of signal.
If you're still not getting results, the best option would be to install an adjustable line preamplifier (sometimes too much amplification can degrade the signal); this preamplifier should be LTE/4G filtered.
Here is a good product, for example:

And what does that give, because here's what happened to me: progressive loss of R1, quantity 100%, quality at a minimum... I went up on the roof and removed a TV/FM coupler, worse! quality 0
But I realized when unplugging the antenna that there was a fleeting image... and a stable image while keeping the plug "almost" plugged in. Then I remembered having removed a splitter for the living room + bedroom that I didn't need, and since I removed it => too much signal
I went back up on the roof and decreased the amplifier by a third, the quality went back up to 100%, no more problems
Hence my advice for a filtered 4G/LTE pre-amplifier that is adjustable.

Good evening
I know to display the frequency [...]
it's not working, I can only enter 778.11 but it doesn't display anything
The frequency to display is 778166 do not put a comma....

Very difficult to catch a black cat in a dark room.
Especially when it's not there...
Not having the same television model makes it difficult to imagine the problem.
On Samsung, you can modify the frequency (without a comma), or the channel number.
On the Thomson 40FS3013, the manual on page 8 (9 of the pdf below) only mentions frequency.
You write that you can only enter 5 digits while the setting requires 6, so I thought that the comma was unnecessary.

One more time:
Make the effort to ask a neighbor if the issue is the same.
And also:
"Channel 59 on 778.166 MHz is sometimes disturbed by LTE 4G."
If you have a mobile phone relay between your antenna and the transmitter, it might be messing things up, try to install an LTE/4G rejection filter as close to the antenna as possible:

Is it a FAKE?
As for the R4, what's happening with your neighbors?
