Please help, ive recently purchased a Wharfedale LCD2710HDAF television. Unfortunately some fittings are missing and the instructions don't make it clear what they are or where to get them from. The instructions refer to them as, four plastic pins which go into four holes at the back of the set, in these pins then go the screws which enable it to fit on the wall brackets. If anyone can explain to me what these plastic pins are i would be very grateful. Thankyou. Shane.
