Hello everyone,

My uncle has an LG LED tv (32inch) sorry but i can't remember the model neither call him to ask now, but the problem is really weird so maybe someone had the same issue before.

So, the Tv is working like usual when the sound turn itself off, if we press the mute button twice then a popup message come and ask if we want to reset the sound setting, despite of the option we choose, the sound come back, but only for 30 seconds and then it turn itself off again.

We are using VGA cable with "basic cable box" (i don't know the name) we also tried another box that have HDMI output, the problem didn't happened at all at first, we thought that all this was because of the old box we were using, so i start installing new channels and editing the channel list, and again when i exited the setting menu, the problem come up again, but this time the mute button doesn't do anything.

IMPORTANT for some reason the tv is accepting input from another remote control,
for example there is some buttons of the "basic cable box" remote that when we use it, the LG Tv show "this option is not available at the moment"
i am sure that this come from the Tv and not the Box because of the UI.
Also with the remote control of the new box, the "power button" turn on both devices (tv and box) but it only turn off the box, also the button that are made to navigate through the box menu are somehow used to increase/decrease the Tv volume, also am sure because of the UI.

Thank you very much i would really appreciate your help.
Have a nice day
