That's not the power supply -- does it make a sort of humming noise while
doing this? I can almost guarantee you that this is merely the degaussing
circuitry at work. The purpose of degaussing is to realign (internally)
the monitor with ambient magnetic fields. You may have experienced at some
time (usually with older, larger monitors) that after _moving_ them, or
turning them more than about 15 degrees, that the color kinda goes funny
for a while? That's because the monitor had adjusted itself to the magnetic
field patterns around it in its previous position. Then, you shift the
field's orientation, and it takes a while before the interaction nullifies.
Degaussing circuitry somehow makes this readjustment automatic, and only
turns on when it detects the neccesssity(sp?) to do so. If you have another
monitor nearby, have it turned on, turn on the seiko, degauss it, then
turn them both off, and then turn the seiko *only* back on, you will notice
that the colors may be shifted funny, or get effects similar to when you
hold a magnet to a TV screen... We had acouple of monitors that were next
to usesless -- because they had to be degaussed manually! Once we learned
what that little button was for, presto! Three perfect-condition 21" analog/
RGB multisync monitors! :-) (stop drooling!)
