Yes, It's that simple. Just make sure that the power cable has a transformer that reduces the 240v mains to 12v and your sorted. Just go to Tesco and check the cables on the tv's.T:Can anyone help on this, Im stuck whether to pay extra for a proper 12v LCD TV ive seen on Ebay or just going to Tesco and getting a normal lcd from the shops that works of 12v is it that simple?
