I have a Samsung TV model number HLN437WX/XAA. I spoke with Samsung on the phone and they said I needed to buy this http://www.samsungparts.com/part_detail.asp?oldpart=BP96-00224C&catalog_name=Parts+and+Accessories&category_name=&product_id=BP96-00224J&search_model&cookie_test=1&cookie_test=1 replacement amp. Is this the only lamp that will work for this TV or is there other options I could be looking at?
