They have the operators manual for your unit on line at:
http://www.sonystyle.com/sonystyle/4784/5210/5272/5240/3941.default.html
This page has the FAQs on the wiring, which are the same as in the thread I posted above, but the colors on their web site don't seem to match up to your description! I would contact Sony for their wiring manual for this unit.
