Hi all,
I have some convergence problems on my Naomi Universal Nanao monitor in the four corners.
I made four strips 10 cm x 1 cm with magnetic tape on it (as you can see in the picture).
I never tried to fix this problem, do you think the strips I made can work?
Thanks!
Marko

Re: Convergence strips Nanao
They should work, best way is to give it a try.
I will be interested to see how you get on - have one to do myself.

Re: Convergence strips Nanao
The corner convergence strips used by CRT manufacturers are not magnets, i.e. they don't generate a magnetic field. Instead they are made of materials such as permalloy or ferrite that shield from a magnetic field. In other words, if you put them close to a ferrous metal object, they don't attract it.

Is it simple to make those up? what would you use, I get the feeling some are doing it wrong and using those flexible magnets like you stick on a metal fridge.

Re: Convergence strips Nanao
Wild conjecture having successfully used strip magnets in the past - wouldn't the fields from the yoke and degauss coils demagnetise them over time anyway?

I use the ones I take off TVs. I have at least 1000 so if you need some let me know.thegreathopper wrote: ↑October 17th, 2021, 11:03 amHi MKL,PrincessPrinPrin wrote: ↑October 17th, 2021, 9:08 am The corner convergence strips used by CRT manufacturers are not magnets, i.e. they don't generate a magnetic field.

Re: Convergence strips Nanao
I need some, as soon as I have recapped my chassis I plan to have a go at the convergence issues, Will send you a message.
Thanks.
Thanks.

Hi,
this is my current situation, I also tried to move yoke rings.
The problem is in the right corners, center is perfect.
