A:AnswerYes there is. There are RCA converters you can buy if you're really looking to keep old equipment. Though the quality of the picture won't be very great since it will be standard definition on a 4K tv, and might even have black bars around the images.
A:AnswerBlu-Ray - yes - the product has two HDMI inputs. Regarding sound system - depends on the connections you need. Suggest you review the specifications closely before purchasing - this product is a hot deal - but does have limited connectivity options.
A:AnswerR u asking the delivery date? BB will deliver directly to ur door or where ever u want to place ur TV. U just need to choose the date that u want to deliver. on your delivery appointment they will give u a call and confirm it. they will not mail the TV, I think bcoz the tv is big and fragile but mine was delivered on time.
