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,

Have you tried removing batteries from the remote and seeing if the remote is defective? Rather than the TV itself?
