|
|
Ok I'm doing the Magnetics again. It looks like the center is perfect[I think] I can't seem to get the red to reign in. The grid is too large. Turning the red high and low band slugs has had no affect whatsoever. is it time for the SUPER SECRET menu timings.
The CVA and STIG cables are not plugged in in these photo and no convergence or geometry has been done either.

The double images in some off the photos is not from me. The camera is on a tripod and I can see that ghosting shaking on the screen too. What's that from?

i havent touched them ever but maybe you need to put the size on 50 first(hor) before adjusting.

Remember, when you do the tube pivot and before doing the convergence the edges should be aligned. The middle will not be.

Hey Scott thanks, even that way the RED Grid is much larger then the green and blue. The green and blue will line up edge to edge like your picture, but not the red, is always larger.
What's causing that?
I was just about to take a picture of that way too for comparison. I will post it shortly.

I've read this many times, but never been able to put it into practice, and maybe adjusting the linearity is the key - because when you adjust the center convergence point, it moves the whole grid! Is it linearity that is used to line up the center prior to convergence?

The whole grid moves when you set the centers to match but that is ok. The point convergence will pull things in. Try the guided convergence once the zeroed out convergence and tube pivots are set like the picture.
Dturco, is your red deflection yoke pushed all the way forward against the bell of the tube? The red image shouldn't be dramtically larger than the other two.

Good question, I don't know I'll check it out. [Knowing you, you already know it's not.] 
Thanks again TSE rocks

can you do s & c linearity for the colours separately?

I'm confused. That pic looks OK to me and I have never seen much better than that. It's due to the limitation of the 3 CRTS are not on the same vertical plane like horizontally. I thought you are supposed to center raster by viewing edges then measure width for red and adjust width for B+G to match red then tube pivot R+B in center which should avoid drift in center then adjust the rest with geometry and convergence?

Not that I can find.

how are you adjusting the width for each color separately? I have tried the width slugs they do nothing at all.

The red sweep coil might not have been not fully against the tube face, it was very easy to swing. I did push it tightly forward and then all of the other magnetic coils too. There was very little movement if at all. The red is still larger then the green and blue.
Could the CLM be weak, and cause this?

you adjust the green coils to get the raster as large as possible. then adjust R + B to match green. I've never had a problem doing except for the coils that got bound up in the paper tube and cracked/crumbled. Those I had to replace.
your lining up the edges like Scott showed, convergence will push/pull/stretch the center zones to match green. That's the way the machines is designed to be set-up.
