Any tips on this would be greaty appreciated as I'm a bit stumped.

My Viewsonic P815 monitor works great, but it has an annoying buzzing
noise. Great picture. The noise seems to be coming from a small board
attached on the top of the tube. (has tons of small wires leading
arouund the tube attached to about 20 wire wrap posts on this board,
compensation board?) I poked around with a stick and touching this
board causes a change in the buzz but doesn't quiet it, it even seems to
get a bit louder. I can't seem to localize it within that board using a
hose. I'm a but stumped... I figured I would poke around with a stick
and when I hit something that made it quieter, I'd put a little hot glue
on it.

If anyone has a tip or two I'd be grateful. This is a killer monitor,
but I can't stand the buzzing...

Thanks in advance!

Could this be a relay on the board? If so, it may be an easy fix.

Is that the junction board on the deflection yoke? If the yoke is noisy a
dribble of glue might help.

That is what I thought it might be... but the noise doesn't appear to be
from the yoke, but the junction board itself. The board has a few coils
on it, but they don't appear to be the source of the noise either. Its
possible my detection methods aren't accurate enough to pinpoint the
source on the board though.

Maybe I'll try poking with a smaller diameter stick.

Thanks for the ideas!

Another idea is find a piece of flexible plastic tubing, stick one end in
your ear and poke around with the other listening for the source. Be careful
not to touch exposed connections, they'll bite.

I've been a P815 owner since 1997 and also love the great picture but
can't stand the buzzing. This thread ended before you ever reported
success or not.
