Monitor picture is wavy.. gets worse as refresh rate goes up.

I've got a 17" Dell Trinitron monitor that's older, but still seems to work fine, except for a few quirks. First, the picture seems to have invisible "waves" running through it. Bars kind of roll horizontally through the picture, gently moving anything in the picture. As the refresh rate goes up, this turns into a more pronounced and violent shaking, making the monitor unusable above 60hz. Changing resolutions has no effect (it's currently at 1024x768, 60hz). The old monitor on this machine was a 15" NEC that works fine in all resolutions and refresh rates it's capable of displaying. Is this anything fixable, or shall I start the search for something new?
 
Gee, sounds bad. Fixing it, although it may be possible, may end up costing about what you would pay for a new monitor. This might be a good oppurtunity to make an upgrade. Nowadays 17" is a little small too so you might want to move up to a 19". I don't know what kind of budget you are on but a new 17" should set you back around 100 bucks. Good luck.
 
Do you have anything with a strong magnetic field near it such as a small fan or (obviously) a magnet? Sometimes where I work this will happen where people will put personal fans too close to CRTs and they get all distorted.

I've looked around, but I can't really find anything magnetic. I'll probably just salvage a new monitor... I actually got this one for free from a department that was tossing it. It's not my primary machine, luckily my 21" CRT is still running like a champ!
 
Its your video cable. It is either not sheilded proper or probably fraying near the ends a little bit. You can replace the whole cable (ive done so before on that monitor), but in all honesty its not worth it. If you google around you should find a few stores that sell replacement monitor cables.
