We keep getting a voice over ( maybe for visually impaired) telling us exactly what is happening on the screen.. How do I get rid of it
It sounds like you are talking about "described video". Does your signal come through a set top box before going the TV or is the cable hooked directly with the TV? If going through a set top box first, you need to change the setting in the set top box.

This is because it is a not a free channel. You need topup tv to be able to see it, UKTV gold is an example of that.

This could be 1 of a few things here. Without opening up your set and trying to look at voltages or indiciator lights I couldn't tell you exactly without some more info.
Without looking at it myself here are my thoughts and where I would first look at.
It may be a main board because:
1) Main board processes all your audio/video signals. Bad main board means bad video processing. Could do that. Especially if the main board is not sending the right signal or a bad signal to the rest of the boards so they don't do their jobs.
It may be a power supply because:
1) Power supply is well, the power supply. If it's sending inadaquete voltage to the main board you may not be recieving enough juice to keep that main board doing your video processing or further up the line keeping enough juice flowing to your TCon board to keep it telling things where to go and what to do. The power supply sends voltages to your Ballast board(controls your lights) and to your main board through which power is supplied to your TCon board via a LVDS line and a +12/+16V signals. If the power supply isn't pumping out enough juice to keep the TCon or Main Board running, it could be a problem. By the same token it could be that your P/S isn't sending power out to your ballast board.
It could be a TCon because:
1) If the TCon is bad, you won't get your pictures. This could be the TCon board itself or the LVDS cable from your TCon to your Main. However, with few exceptions, if it's a bad TCon you're looking at a total panel replacement.
It could be a ballast board because:
1) The Ballast Board controls the lighting behind the LCD screen. If this isn't working right you won't be seeing much of anything without that back lighting. If this is bad, it's a panel replacement. These are not field replaceable items by LG.
Based on the symptoms, without more data or a eyes-on view of it, I would say you're most likely looking at a Main Brd or PSU problem.

if your remote has a tool button on it you can turn it off in there if not it is in menu under audio settings
SOURCE: what is the code for a LG 47LF6 LCD TV
LG codes are:0002,0606,0502,0102,0324,0435,0802,0307,0609&0217
press code search until the red light stays on then release-press the tv button-enter each code (four digits)-when you get the right one the light goes out, for an invalid code the light flashes-press channel up/down and you're on your way
