Hello,

Does any one know if a degaussing wand will suffice to the extent a degaussing coil will for use on older arcade monitors? I have an old Ms. Pac man which has a purple discoloration at the top of the screen. After inspecting the board, ajusting, etc, the color remains (it looks like a bell curve at the top of the monitor, and within the curve the monitor is discolored comparative to the rest of the monitor). There is a large price difference between the two but I also wish to find a tool which might help. Thanks.
 
I see that, but my question is in seeking a comparison between a coil or a wand. I also found a degaussing 'stick' I'm assuming this is also a wand?
 
Yep, the same thing... I say the coil is better


Why, if I might ask? There is a large price jump. Paradise arcade has a 'stick' that looks appealing and I feel like I need a degaussing tool but I still can't find enough information to make an informed decision, other than amps, watts, etc.
 
you want a coil. a smaller red/pink one will barely get the job done, if you want one with some oomph youll have to drop the extra money on the big black one

the stick or wand would be giood if you wanted to erse some tapes, but it just isnt strong enough for arcade applications imho

The right tool for the job is the big coil. It's more expensive but those cheapies aren't worth it. You'll just end up buying a better coil and the cheapie will have been a waste of money.
 
Ok, thanks for the feedback. That is what I was looking for. I will grab a coil this week.
 
what exactly do you do with this? just start in the center and do circles moving away? Any risks with using a powerful magnet?

Yes, I pretty much start in the center and make circles and move the colors to where they should be.

No risks I know of. I tried a soldering gun but it would not push the colors around enough and correctly.

Remember to buy a nice demagnetizing coil when the tray method leaves off color in your monitor.

Nothing worse than someone magnetizing the metal brackets on a monitor or getting a magnet too close to the convergence magnetic rings on the neck of the tube.

I have been known to toss out a brackets and get new rings to fix problems like that.

Well you only wave the tray over the screen, not the chassis or neck of the tube and do not hold it to the screen.

I've never had an issue and it's just like using the drill magnet method or more then one magnet method. I used to use the solder gun method, it was not strong enough for this particular application, the person working on the chassis can decide what's best.

I have a beautiful picture on my WG4600 now!

With skilled hands, You can get perfect results using drills and permanent magnetics . The Coil is still the best way of going if you do not have skilled hands.

When people attempts of repairs don't work. Some will be temped to waves the magnetic source at the neck of the CRT and demagnetize the convergence rings.

If it looks curved like a bell then i would take picture of the yoke area.
It the yoke has move back alittle or a rubber wedge spacer fell away and the yoke
is not straight the purity will never get right..Mechanically everything must be correct.
If the puity ring have fell out of position,it may look similar.
Confirm the yoke and rings are correct first then degauss.
Normaly small amount degaussing is needed when games have been turned,while on.

Check the G07 service manual for more details on similar type monitors for adjustments.
And see pictures of how it might look normally. I believe Happ sell's degausser's
Good Luck!

Just degaussed my DK monitor using a trigger style soldering gun. Just point the tip the oppisite way. Worked like a champ.
 
I have tried the drill and soldering gun method and they did not work for me. What does work for me is basically what Toolguy was saying, a big magnet. I use an old 6x9 speaker, only on the front of the monitor, and it works like a charm for me. I have only had a couple monitors with degaussing problems so I'm not saying it will work for every one but the two I did still look like new.
 
the best coil on the market is one that you make from dead monitors.

Take two deguassing coils (prefferably from 19" or larger) and twist them together like a bandsaw blade. Wire them in series with a momentary switch and a cord for a wall outlet. Tape the whole works together with black tape. This should take 120 volts without any problems. I've never found a better one and it cost me a switch, a power cord and two free degaussing coils.
