I have just received my TV today, purchased as a refurbished item via Amazon Warehouse.
The reception recieved via the supplied aerial is quite poor in my area and I would be disappointed if this were my only option - but there is a socket for external aerial. I have connected to Sky via an AV sender. You should check your own AV sender compatibility to do this, as TV doesn't have a scart socket.
The sound quality is bearable, but just tried them with PC speakers and there is a definite improvement.
Obviously it isn't "cinema" but is perfect as a smaller option for my kitchen!
