TV LG 26LC2R-ZJ: No Sound Issue, Volume Control Working, Red Speaker Graphic & Voice Displayed

On the TV, as in the subject, after turning on the TV, it turned out that there is no sound. The volume control works properly (graphics). However, in the upper left corner of the screen there is a red speaker graphic symbol crossed out and the word Voice next to it. I abolish it?

And isn't the home theater sometimes connected via HDMI?

And the tv isn't just muted?

The badge just showed up there .

That's possible. Sometimes the simplest things happen. But it should work so that after pressing "mute" and reporting this function is canceled. I just checked it on my LG and that's how it works (well, it should, but I preferred to check it for the hundredth time ).

No, it's not muted, the voice level (graphics) is 100%, hotel mode is off. The stamp appeared by itself after turning on the TV. Anyway, the mute badge is completely different, in the lower left corner of the screen and has the same color as the graphics, i.e. orange and I can call it and delete it with the remote control and it has nothing to do with the badge as in the picture. TV due to mute went to the "corner" for now
I currently do not have access to TV. But when I have the opportunity, I will try Darek's method

Reset the tv to factory settings - then you will set everything up again.

...heh, just reset with what and where? I dug through both service mode and hotel mode and it didn't help. Reset on this TV is only in the menu but it does nothing. I tried in every way. Adding a voice, the graphics go from min to max and the speakers are silent. The only sound this TV currently makes is noise in the speakers after switching the system to DK. So it can be assumed that the amplifier is operational because even using the equalizer changes the color of this noise. In the BG system on the scart connector and in HDMI, complete silence.

The question is, do you still have this symbol of the crossed out speaker, because if there is noise ... And by the way, DK / BG, try to tune it to an analog channel (maybe you still have a video recorder with a modulator ...?. This may resolve the issue of the ending. And connect another TV set to Scart in AV mode.

Yes, after switching to the DK system and the noise is still there. A DVB-T Synaps 2910 decoder is connected to the TV, which has scart, HDMI outputs and a modulator for channels 21-69. All outputs are connected to the TV. There is a picture on all inputs and silence on the speakers. Only after switching to the DK system there is noise, but the symbol does not disappear. And everything was working until one day this symbol appeared at the top of the screen. The tuner works fine on other TVs. I even checked the power supply, all voltages are normal.

I understand that this symbol is different from the one that appears after pressing the "mute" function. You have not yet checked if there is sound on the scart output when controlling the TV from the antenna input. After all, as you write, you have a DVBT tuner with a modulator ...
But I think the phone will be...

when we connect the home cinema, it turns off the power amplifier and the volume on the TV remote control takes over the control of the home cinema. And also there is a symbol of a crossed out loudspeaker, and it seems to be different from the one with "mute". At least that's what I had in such cases, but with much newer TVs. And that's why I wrote it. And answer, did you have the HDMI connected from the tuner all the time during these tests? If so, disconnect it. It is possible that for some reason the TV interpreted the tuner as a home theater. I understand that it was working normally before, because you didn't explicitly write it.

OK, you have already answered one of the questions

Well, I'll answer the rest of your questions
There is no home theater connected, all inputs worked normally until this badge appeared. The HDMI input is connected to the NC+, scart to the JCG recorder with a disk and the synapse to the antenna input. I didn't try to record anything after the voice faded out. Now, as I wrote, I do not have access to TV until next week, I will check the options for the presence of a sound signal on the scart output. (I will record something on the recorder)

You can but you don't have to. And so, to check, you need to connect this recorder somewhere. All you have to do is connect another TV set to AV to Scart and tune the problematic LG to Synapse via the antenna (on BG and DK because I don't know how it is now and what's the harm in checking both - noise ...) And what I wrote about home cinema fits perfectly to the symptoms... only you don't have a home theater. But

At the same time, when I wrote this, I didn't know what and where you have connected. Now, an NC+ tuner via HDMI may come into play, but also a recorder via Euro (because there were and are communication systems for devices just after Scart - even in modern Vestels and derivatives). In older Panasonics, just after Euro, the recorder copied the list of channels from the TV . Therefore, you should check each device separately, completely unplugging the others (except maybe Synapse, because the one after the antenna should not mix anything )
Personally, I'd bet more on the recorder. Especially since both it and the TV come from a time when HDMI was not so common. But of course it can be a completely different matter. I'm just following the home theater trail I started with

welcome back
Today, after a few days break, the TV was reconnected to the network and it turned out that the described fault disappeared spontaneously as it appeared spontaneously. Earlier attempts to disconnect from the network, even for a few hours, did not work. Only a few days "post" unblocked the voice.
The connections to the TV are still the same so it's probably not the cause of the fault
