Should I fix this?

[monkeybomb]

I have a monitor that came in a very cheap dynamo cabinet.  I thought it would be fixable but I realy have no clue.  There are 2 problems.

1.  imagine a layer of water over the monitor with a wave maker at the bottom.  it is consistantly making wate movements.  This is different than just a line scrolling from bottom to top, it is creating waves.

2. there is a purple spot in the upper left corner.  Degaused it with the button and manually and it was no help.

Pictures, please.  And make/model of the monitor.

DOH! it will have to wait til tomorrow.

Okay, this is the best I could do for pics.  It's a shot of the purple in the corner and the back of the monitor for model.  The thing that has me wondering if I should try to fix it is the under water effect and I can't figure out a way to take a picture of that.

Cabinet speaker magnet and/or the fluorescent light ballast could be affecting the corner color.

Concur with Ken....  But I have to ask this... Where are the convergence magnets on the neck of the tube???  That's a pretty dang long neck, and unless I'm getting really old, I can't make out any convergence rings on it!

I'm not sure what convergence magnets are.   I'm also not sure of the make and model of the monitor.  I'm completely new to monitors but would realy like to fix it myself if it can be done within a reasonable price.  I am aware of the risk and have read how to discharge the monitor a million times.

But the only acctual I have read much about is a cap kit.  If that, or something without much cost, might solve my problems then I'll give it a shot.  I really want to know if there is a point in tring to go for it.  If I start I will most likely become obsessed so I am cautious about starting any real repair.


If I am not able to remove the purple spot by changing the speaker with one that I know is sheilded, might it be fixed with a cap kit?

Also would a cap kit most likely solve the waves that flow over the monitor?

Can I take pictures of these waves some how?  It's seems impossable to take a still of movement.

Is there a chance one of these problems is just unfixable?

What monitor might I have?

If you can't tell what area of the monitor do you need better pictures of?

I hope these are better questions.

Bump.....I'll be taking this cabinet on thursday, and need some advice on this thing. Are the symptoms that monkey speaks of fixable with a cap? Thanks for the help everyone, its very appreciated.

One of my TVs has that same wave and so do many games at my local arcades.

That appears to be a new Wei-Ya 826H replacement chassis connected to the tube.

If you are seeing a wave, it's likely you don't have an RF noise filter on your incoming AC line (before it goes to the isolation transformer) and/or you have the isolation transformer (or other transformers) located way too close to the monitor.

E.g. my Electrohome G07 has a nice wave in it in my Ms.Pac cocktail because the 2 AC transformers are about 1" from the neckboard, while the G07 in my upright Pac-Man is wave free as it's about 2 feet from the transformer board. (Yes, both have cleaned edge connectors and fuse blocks )


And I *still* cannot see the convergence rings on that tube... I'm VERY confused by that.  This is what convergence rings look like:
