LG 37LD450-ZA TV - No Sound, Headset Connected Error, Tried Factory Reset & SCART Removal

Hello.
I am asking about the cause of the problem in the lack of sound in this TV model.
Despite the lack of any speakers / headphones etc. connected to the Mini-Jack socket, the television informs that "the headset has been connected" and does not emit sound. Earlier I used these audio sets for the jack, but I stopped in favor of the recently bought speaker which was connected to this TV model with the SCART connector. I noticed the problem when switching from one audio system to another. I tried restoring factory settings and disconnecting any audio devices from the SCART connector and from Jack - both unsuccessfully. I make an inquiry here - on the electrode. Servicemen and professionals - help!

The micro contact in the headphone jack may be damaged Pay attention to this

When using headphones through the headphone jack, the sound is emitted - not unplugged. So I understand that this micro contact can affect this?
In addition, would repair / replacement of such a headphone jack cost a lot and can it be done at home or better through the service?

There is a micro contact somewhere that gives information to uP whether headphones are connected or not. If the message is still displayed, this is something You have to check it out. If you don't know it, send it to the service

Okay, thank you very much for your reply, it will be checked and at best exchanged by a service representative

This is not 100% certain But the service technician will definitely handle it

The problem is solved - the problem is eliminated by sending the device to the service - the guest replaced the Jack socket and everything flashes beautifully.
Thank you for all the help - topic closed
