For those that are thinking about buy this equipment and like me research a lot before taking out the credit card, there is a clue. It is surprising, but the user's manual for the 47LB1DA is not available on LG US Web Site and there is just a poor brochure for download. Incredibly the customer support also doesn't have this manual. Go to the Canadian LG Web Site (http://ca.lge.com/en/products/mobile/mobil/sidemenu.do?action=list&group_code=0101&list_code=PRD_MANU&target=manulist&categoryId=0101&modelCategoryId=0101&parentId=01&gcscId=CTV) and there is a complete pdf with 128 pages in three languages (English, *Canadian English and French).
This is only useful if you want to know better the general characteristics and the features of this outstanding LCD TV, but this doesn't substitute the opinion and the experience of those that already bought the real stuff.
