Is the order of turning on/off equipment a factor?

This has been happening with a friend's Samsung TV, Yamaha receiver, and cablebox for three years. But looking back at Samsung HD tech's post number two, could it be avoided by making signals available to HDMI-CEC equipment by turning on the cablebox first and turning it off last. Or some other order. Could you guys try it and let us know?

You guys are right tons of folks must be having the same problem. It's too bad for ARC users if HDMI-CEC needs to be on for it to work.
