I have a Sony Home Theatre System DAV-DZ20. I used to have a CRT monitor previously. But now when I try to hook it up with my new HD monitor using component cable, the images are all red. I'm using the component cable to take advantage of the progressive scan available on the player.Colours are fine while using RCA. I read in some forums that this is because the video output has to be changed. But I can't find this option on my remote.
