I've got a Qix that has definite convergence problems, and also seems to need degaussing. Should I adjust the convergence before or after the degauss? Or both? Or does it not matter?
 
Always degauss first. Any time you do convergence on a monitor, always degauss it first - even if you don't think it needs it. The magnetic field will affect the convergence, and it's important that you start off with it all cleaned up.

Also, don't bother trying to converge the monitor before setting the purity either. If the guns aren't hitting their color, then you'll never get it aligned.

So, the steps are:
Degauss
Set purity (solid red, green and blue screens with no "splotches")
Converge center (rings)
Converge edges (yoke tilt/strips)

Thanks for a great answer

Useful to many :)
 
my method is degauss, curse. adjust rings, degauss. Curse some more.

repeat untill pic looks good or you threw a hammer through the tube.
 
I was just looking around for a degaussing coil. Bob Roberts and ArcadeShop (both places I've ordered from before) have them, but ArcadeShop has them for $25, Bob charges $40. Anyone know what the difference is? Is Bob just selling a heavier duty unit? Or he just sells fewer, so his price is higher? Or does his have a switch and the ArcadeShop one doesn't?

What should I be looking for in a degaussing coil?

The cheapest round one on Ebay right now ($26.99) has a block of text that makes me think the seller is a real sleezebag (lots of 'The secret that tv repairmen don't want you to know!' kind of crap), the rest are $49.99 and up (at which point, I'd REALLY rather just get it from Bob, because I know I won't have a problem.)
 
OK, here's question showing my lack of knowledge: I want to adjust this monitor (it's pretty out of whack). I understand I turn the rings on the neck (CAREFULLY!) to adjust various stuff, and I understand I'm supposed to work from the inside outwards on the neck.

What I don't understand is how I'm supposed to see what I'm doing! I suspect I'm just missing something obvious, but the only thing I can come up with is to set up a mirror so that I can see the front. Is that the usual technique? Or am I supposed to take the glass & bezel off and reach around the monitor to get to the rings? (This seems bad to me, as I'm not real comfortable poking around blind near monitor voltages!)

So, please clue me in - how do I adjust the monitor on my Qix (assuming that I don't want to take the monitor out of the cabinet. Or is that the way to do it?)
 
Usually you dont need to touch the rings.. Can you post a picture/video/describe
what it looks like?

The colors change across the screen, and the convergence is definitely WAY off, and both problems are easily seen when playing, not just when the test pattern is up. The degaussing coil had no effect, so I really think I just need to start from square 1 on adjustments.

I don't know if the ride home (the Qix was on it's side for the 3 hr ride from DC to my house in PA) knocked everything around, or if it was off from before, but it's REALLY off kilter.

Does it matter if I cap the monitor before or after adjustment? I'm thinking that it shouldn't matter much, but I suppose that's something to ask.

Ding! Ding! Ding! He missed something obvious in the first sentance, and stumbled on it in the second! :D

Yeah. Use a mirror. :D

Or, you can pull the monitor out and work on it at the bench. But, if you don't have a test bench set up, ithen you'll have to do it in the cabinet.

If the convergence was OK before you moved it, and now it's out of whack, try rocking/turning the yoke first, and see if it's loose. If it slid down the tube a little, that'll screw up the convergence too.

I'll try that - I'm actually NOT sure if it was OK before I moved it, we didn't do more than a quick 'yep, it's got a picture' test at his house before loading.

Thanks!
