I was helping someone out with an old Pioneer Elite plasma (is that the Kuro line), and an issue came up. When I hit the power button on the remote, the screen would go black and the status light at the bottom left corner would change from green to red. However, I could definitely see the backlight of the display. From what I could gather from the documentation, that meant it was in standby mode. I assume that this is to shorten/eliminate the warm-up time for the set. What puzzles me is that it seems that this is the only state the TV will go into. I couldn't see any way to put it into a full "power off" mode without cutting the power.

This TV has a breakout box that handles all the inputs. Both the TV and the box have power buttons, but it seems like neither of them fully turn off the backlight. Is this weird or is this expected behavior?
