Hi Shaun, There are 2 types available. The BN81-12884A is very basic (and useless). The BN81-14946B is a much improved one. Google them.
I've never used them. I use a wide blade pocket knife. A cutlery knife would also do. With TV on it's face, you'll see a little cut-out in the bottom right corner (underside). Prise it up with a screwdriver and slide the knife in bout 2.5" under the cover bout 3' upward and twist the knife until the first clip releases. Take care on this one as the rear cover becomes brittle with age and can crack. After that, put upward pressure on the cover and move and twist the knife anticlockwise around the rear cover as you go around. there are no items that can be damaged. Don't touch the bottom edge - it'll unclip when the cover is free. compliments Bruce
