RE: Monitor degaussing help wanted pt 2

1]Unfortunately, when I plugged the monitor back in, it looked just as bad
as it had before. My degaussing procedure seemed to have had no effect.
So, here are my questions... given my brief description of the display
characteristics, was I correct to diagnose this as a degaussing issue?

In a way, yep - purity problems are usually corrected by degaussing the
monitor.

2]If it's something else, have any idea what it is?

See my part 1 msg :> Could be the purity rings, yoke position, high
magnetism on the shadow mask, or the shadow mask itself.

3]If this is still a degaussing issue, are there any tips for improving my
technique?
 a]Specifically, how long should I take to degauss the monitor? 1 minute?

 It depends on how bad the monitor needs degaussing. Usually around 15 to
30 seconds takes care of it. If it doesn't, then try it again. If the
problem gets better after each degaussing, you're on the right track. If it
looks the same, that's not a good sign. The most I've had to do it was for
about a total of 2 minutes after someone took a rare-earth magnet and stuck
it to the monitor face to show one of his coworkers how 'neat' it looked.
(ack!)

 b]Should I make rapid spirals around the monitor face or slow paced ones?
I was holding the coil so that the "O" was parallel to the face of the
screen. That is, the monitor is facing horizontally on my workbench, and the
"O" was being held straight up and down. Is that correct?

 Usually, I leave the monitor turned on with a full-field signal applied. I
usually like white, then switch between r, g, and b to check each color.
With the monitor on, I keep the degaussing coil around 6 inches from the
face and turn it on. Going in circles, I start with small circles and
progressively make larger and larger rings around the monitor while pulling
it back. I usually do one ring per second to start with, and end up about
one every two seconds at the end. At that point, I'd be around 6 feet away
from the face of the monitor with the ring edges just going outside the
edges of the CRT. Then I'd turn it so the face of the ring lines up with a
side of the monitor and pull back to around 10 feet, where I'd turn the coil
off.

 Oh, and make sure you don't have anything near you that you don't want
degaussed! (credit cards, ATM cards, analog watches, hard drives,
diskettes, magnetic tapes like cassettes and videocassettes...)

HTAYQ (hope this answers your questions),
