Hello, hope someone can help me here.
I have and old IBM 14 L10 crt. The problem is that the left and right sides are bend in of the screen. I think that's called the pincushion effect.
The buttons don't do anything anymore to fix it.

Opened the monitor up and saw a broken part. I think it's an inductor but don't see any part number for except "L-713" brand is sumitomo.
Can't find anything on it on the internet.
There is somekind of coil in it.

Somebody can help me to find a replacement.
See pictures how it looks like.
