Not strictly about puters,my new posh telly has numerous inputs also on the back is a USB socket that says 'Service Only' that does not appear to do anything,probably for service engineers only,googling on a totaly different matter one stumbled upon a item that told of a way to activate this USB input for normal usage ie looking at stuff, movie clips photos ect on a USB memory stick.
Any of the knowledgeable peeps on here tried this sort of thing.??
This is the link.
