robotron cocktail degauss needed...?

[fixedpigs]

so i moved my robotron cocktail...it was facing east/west...but now it needs to be running north/south...

the problem is that when i rotate it ninety degrees...the colour on the right(east) side fades drastically...

am i going to need a degaussing wand or is there a better way to get the monitor back to normal...?

thanks...

Are you leaving it OFF for awhile before or after moving it ?

The auto degauss only works when it's "cold".
(if it is working at all)

it was off for at least two months...
i then moved it to a new house where it was oriented north/south...
i turned it on to find that the right(east) side of the monitor was faded...
i then rotated the table ninety degrees while it was on and the colour returned...

Anything magnetic next to it ? Speakers, other machines ?

nope...not at all...

i was figuring that the magnetic poles were affecting it since the monitor lies flat...

[Level42]

Yes it does have more effect.

[fixedpigs]

so here are some photographs of what i'm talking about...
running north/south and there is the fading on the right side...
running east/west and everything is dandy...

Looks familiar -- my Joust cocktail is the same way. If I would rotate it, even temporarily, it would end up needing degaussing, even after moving back. I used a corded drill waved in circular motion over the affected area when I didn't want to wait for the degaussing coil to kick in. Worked OK, although the drill has since died.

As the fates would have it, when I rearranged the games, it has ended up facing so that it had no problems at all.

How did you degauss with a drill?

exactly...!

how do i degauss this thing...?

thanks...!

Place the drill body parallel close to the problem portion of monitor, start it up and move it in circles gradually increasing the diameter and distance from the screen. Can also use a soldering gun (not iron, but a gun).

Randy Fromm has some magic words that he recommends you recite during the process, but I don't have them handy.

move it clockwise...counter-clockwise...does it matter...?

should the drill itself be spinning clockwise or counter...does it matter...?

thanks again...

[CheffoJeffo]

Doesn't matter -- you just need a moving, fluctuating magnetic field.

In theory you can do it with static magnets, if you can move them fast enough.

You can also stick small pieces of flexible stick-on magnet strips at key locations on the outside edge of the tube. (As was demonstrated by Mr. Rick Nieman of Nieman Displays)

You could also place it wherever it is going to stay and lay a 19 inch TV face down directly over the tube of the game monitor. Turn on the TV causing it to degauss itself, thus degaussing the game monitor at the same time. I've done this a couple times and it always works nicely.
