I purchased a used PB7100 that came with no cables. I'm able to hook my laptop up and get a great picture but when I tried a generic HD15 to ypbr cable I only get the Y information. The manual calls for a 50.J2401.001 HDTV cable but from googleing it seems to be NLA. My question is, does anyone have a pinout so I could build one or know where I could buy one. Thanks in advance!
