RE: monitor degaussing

I degauss with the machine on. Then I can see what is being hit by the
coil.. Some areas may need more degaussing.
 
There is a difference in how the tubes are made now.. Not certain what
the deal is.....

This brings up an interesting question I had the past 5000 miles to
ponder as I have just returned from a "drive all over the planet"
vacation. My conversion van has a standard "tube" monitor in it... How,
come I can drive all over creation with it, and never have a degaussing
problem, but when I move an arcade game across the room it becomes a
mess? What is different in a newer TV vs a newer monitor (be it vector
or raster)

And why degauss off? My electronics teacher taught us to do it on

Yep, that's it -- back away about 6 feet if you can.
 
Do the procedure w/ the monitor OFF.
  

Monitor off doesn't matter too much (after all the built-in degauss
obviously runs with the monitor on). It's way more fun to degauss with
the monitor on.

Doesn't matter if there are a lot of games in the room as long as you
can get over 6 feet from all of them when you turn off the coil. If you
can't get that far back another option is to plug the coil into a Variac
(variable transformer) and slowly turn down the power (no less than 5
seconds from full to off).

UNPLUG THE COIL WHEN NOT USING IT! Most coils have momentary switches,
but I've seen some that could be left on. A coil left on will get
seriously hot and self destruct, possibly causing a fire.

I never really thought about it before, but degaussing a game that uses
tape cartridges for sound, tape for the program (the old Deco cassette
system), or hard drives or floppy drives could be seriously damaged by a
powerful degaussing. The built-in degaussing isn't a threat (not that
strong and doesn't wander around the room).

Also, take off your watch, especially modern watches with analog faces.
One tech at my Real Job always had to reset his after a degauss because
the hands would spin at high speed when the coil was on.

Also, I've had a case or two where the monitor metal frame had become
magnetized. In this case, I 'degaussed' the sides of the frame, then
degaussed the CRT using the normal procedure.

        Thanks for all the advice. I have seen this done when I
        picked up my very first machine from an op. He had it in the
        middle of the room, but I have 13 machines crammed into my
        basement and was wondering if they should be isolated and
        also what the best procedure is. What I saw him do was a
        circular motion gradually backing away from the machine.
        Thanks again, Mike
