Question about LG 47 in. Flat-Panel LCD HDTV
TV will turn itself on at random times and when it does the volume surges to 100%. At other times you can be watching TV and all of a sudden volume will surge and you can no longer change channels or control volume even after turning it off on the tv itself, remote no longer works TV when this happens.

One possible thought is to change the batteries in the remote itself.

I also had this same problem. Both the original remote and my universal remote failed to give any response on the TV. Normally the green light flashes when it receives a command from the remote. Called LG Support and they made me an appointment with a local repair company for 3 days later. This seemed pretty quick compared to other companies repair times I'd read about. However next day the repair company called to say it would be 5 more days before they could get a Tech to my location (downtown ATL). 8 days was a long time to wait but once tech arrived he diagnosed it to a bad board and simply went to his truck and swapped it out with mine under factory warranty. Everything has been fine since.

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.
