I want to watch concert videos played from my Blu-ray player, shown on my Sharp LC-52LE830U, with audio run from Blu-ray through my vintage Luxman integrated amp with no HDMI (only RCA audio) inputs and external speakers. I want best picture possible, with no time delay between the video image and sound. Also, distance between the TV and the rack containing both the Blu-ray and amp is about 20'. Thank you.
looking at your tv manual looks like you have an audio out jack (p16 in the manual) so just get a cable like this 3.5mm to 2-Male RCA Adapter (select your appropriate length of course) and you will be good to go.
