The oddities of what you may see on screen during power up and power down could be explained by an electronics engineer or most physicists. But today's consumers may take such normal effects as a sign that something is wrong. I had some thinking that a certain lighting system still used electrical power when turned off because of the afterglow.
Sorry, but if the vendors can't see their way to explaining how TVs and such work, you'll have to hit the web on sites like howstuffworks.com to catch up on electronics, projection systems and more. I can't condense all that you need to know in this small space.
-> In short, it's normal.
