The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.
Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.

I have had the exact same problem with my 47LG70 after 13 months of use. I changed my remote control sensor but it did not help. Before you do that, try something simple which seems irrelevant. On this website, others have posted success by plugging in any standing set of headphones into the remote control or headphone jack on the rear TV panel. This solved my problem. So I proceeded to thoroughly dust all of the input/output component jacks on the rear and side of the TV with an air-can. This solved my problem and I do not need to have the headphones plugged in. So try these two things before changing the sensor.

You either have failed 24vdc power supply section or failed backlight inverter board, check for 24vdc first, look for caps with leaking/bulging top.
