My TV powers up and put the sound level at 100% by itself

Hi,

I bought a 47LB630V TV years ago, but since few weeks, my TV is going crazy.

In stand by mode, it turns on by itself without any user interaction (by the remote controller or by the joystick button). Then, the level of the sound is increasing to the maximum. In the same time, it is impossible to use the remote controller for minutes. When it happened, some time, I managed to decrease the level, but then, it goes up again to the maximum.

I tried to disconnect my TV from internet, perform a reset configuration. I also tried to downgrade the firmware (05.05.35 to 03.xx.xx). The problem stil occurs.

It seems that somehow, it is like a program that forces the joystick button to move to left. When I am in the setting menu, and my TV goes crazy, the cursor is always put on the left-most element.

Does someone already experience that ? It is like my TV was infected by a sort-of rootkit.

Thanks,

      LG TV Stuck Blank White Screen with Sound
      By victoranthony
      Hey everyone,
      I have had LG TV for just two years. Last weekend, when I turned it on, it showed a blank white screen but was still illuminated, with sound working. No LG logo or image appeared. I unplugged the TV and held the power button for 30 seconds while it was unplugged, and the screen issue fixed the issue for a week[url=https://whitescreen.vip/
      ].[/url]
      However, the same white screen problem has now returned, and the power reset trick no longer works.
      Should I contact a local TV repair technician or reach out to LG customer support first?  Any advice?

      Is it possible to send sound to the internal speaker and Bluetooth at the same time?
      By JohnoFon
      I'm hard of hearing, and even with hearing aids I have to turn the volume so high that it deafens everyone else.
      It would make my life easier if I could listen on headphones while everyone else listens to the speaker.

      GOOD sound bar?
      By John Klingel
      I have read a few comments here about sound bars, but did not see much that is fairly new. We just bought an LG 75qned85t TV and would like to add an external sound bar. The reviews we have read so far are pretty discouraging until you get up over $500 or so. Are there any less expensive ones that will improve the sound significantly? It is a bit disappointing to spend this much on a TV and have sub-par sound. TIA. john
