This is one of those every-three-months-or-so questions that comes
up on the Net.  I kind of like them -- like old friends you bump
into now and then...

What you've done in dropping your monitor is slightly dislodge the
internal degaussing coils, and now they're vibrating on power-up.  
They are energized for a second or so every time you turn on your
"cold" monitor.  Normally, they're quiet, being bracketed to the
CRT mounting bracket, but if they get bumped or whatever, they'll
make a distinctive "BWOWMmmm" sound.  Not much you can do about it,
other than open up the case and see where they're loose.  Of course,
I have no idea whether or not this violates any kind of anything that
may or not make it impossible for you to get it serviced in the
future....

Hoping it helps,

Dave
