My father and I are thinking of buying a new TV, Blu-Ray disc reader, and receiver. We have found a great receiver and disc reader. They are both Sony. Because of this, my dad wants to get a Sony TV thinking that the remote will be universal and work with all. However, Sony has ridiculously overpriced 1080p 50" TVs and I am eying a great 50" Sharp TV. Will the remotes work with everything if I get the Sony? And are there any other advantages to having the same brand for all of this? Thank you.
