I got this crt and when I turned it on the image was almost entirely green (see second image) so I used an Amazon degaussing wand (third image) to try to fix it, it got better but the corners are still green (1st image) and should be blue, i tried rotating it but that did nothing but make the screen look weird (not colors weird just scan lines weird) how do I fix this?

I have this CRT and this Amazon $15 degaussing wand and I already ran it over but it left the corners green, is there a specific technique I need to d?

Missing a few consoles and a lot of games but this is my collection so far
