My TV Chassis has developed a magnetic personality!

If you have old focus coil from a early post war set popular mechanics had articles on how to make one into a compound tool magnetizer/demagnetizer. If you have a junk BPC TV I posted a sticky in the TV and radio tech forum on how to make one into a service duty degaussing coil out of one.

If you have a bulk magnetic tape eraser that might work.

Right now, I'm using a Radio Shack bulk tape eraser.
I have a regular degaussing coil I've since 1966, when I first starting repairing color sets, but it's in my warehouse some where.

The Ion Trap is supposed to be adjusted after the set is together.

Originally there was a piece of stiff paper (possibly Fishpaper) attached to the Ion Trap and long enough to reach through the hole in the back of the cabinet. Many of them have long since rotted off and disappeared.

I encountered this problem on the very first one I did, drove me crazy until I figured it out.

Hi Members.i have heard of using a soldering gun to degauss a picture tube in a pinch.never tested since I have had a degaussing coil since I was a kid.

Yes.

After a bit of back and forth, I came to this conclusion as well. That, the trap needs to be adjusted AFTER the set is reassembled. The trap is simply designed to work in this configuration. In this case it's a royal pain because of the surrounding neck shield and how difficult it is to maneuver, working in such a narrow tube. I have to see if I can figure out the best tool to use. So far a needle nose pliers or long flat blade screwdriver have been the best choices but very difficult to use. You can push the magnet in but moving it back out or side to side is nearly impossible.

Also wondering if I should replace the original thick fish paper with new stuff that is thinner and allows for easier adjusting of the ion trap...

Thin Fish paper should work, it doesn't take much to move it around.
There's too much risk of damaging the tube using anything metal. A squirt of Silicon Spray may make it easier to move side to side.
