I just updated my "older" system by replacing the "S" video connections with new "component" connections, going from my Pioneer DVL-919 to the Marantz SR-18 and out to a 51" Samsung Plasma TV. Sound, clarity, etc. is all good but NO COLOR, just B&W! Can anyone advise what the problem may be? I am not an expert by any means so all help will be appreciated. Thanks in advance!
