53 Sylvania up & running

It looks like the beam scatters off of the bell and on to the screen.

That is what it looks like exactly..like a reflection off the bell.

If it's caused by incorrect phase adjustment it'll be a stretched out image. But it's not always easy to tell if it's that. I believe the black band on the right should be about 1/4" wide if the phase is right.

How can I adjust the phase?
Sometimes I think the images of the people look a little elongated..
So maybe I should try this adjustment if you can elaborate. And yes the black band is about 1/4" wide..but what do you mean by if the phase is right?

It sounds the phase is right. I'll have to scan the procedure, it's fairly long, word-wise.

The horizontal linearity and drive might need adjusting also. I'll scan that too.

I went back and looked at your older posts and realize that you do have the Sams Photofact. I also picked up a copy to make sure I don't lead you astray.

I was wrong about one thing. The black bar should be about 1/8" wide. That seems odd to me since my 10" set is also supposed to have it 1/8" wide. That should help with the wrap around on the left anyhow.

If you follow the "complete horizontal oscillator alignment" on page 10, you will be setting the phase properly.

I would also do the "Horizontal linearity adjustment" on the same page.
