You do risk eventually reducing the emission from the blue crt gun
compared to the red and green guns and having a poor picture as a
result. Why not turn down the brightness so the blue gun is not
wearing away the cathode coating material that gradually wears away
with emissions.

Well, the brightness has never been left past 40% for more than five
minutes. I dislike what high brightness and contrast do to a picture.

As for the blue screen; you'd think they'd come up with a blue screen
*screen saver*, much like DVD players have.

I personally wouldn't worry about turning the TV off and on unless it
is a lot more than 4 times a day. I would take my chances compared to
the electric bill that the set runs up by being on all the time. I
wouldn't turn it off for a 10 minute out of the room situation, but if
it were not going to be watched for an hour, I would sure turn it off.

The blue screen has definitely left it's mark. It's imprint is apparent
no matter what I watch. It remains still while the screen moves. It's
subtle, but you can see it esp. when the color provides.

From now on, no blue screen. It's off or to a (non-logoed) channel.

Thanks for responding.
