CRT Colors & Wear?

[Outland]

Hey guys,

I thought I'd start a new thread with a relevant title, as the old one really changed topics.

I've finally gotten the Trinitron running and displaying a picture.

However, the picture is kind of red. Backing down the color control, doesn't fully get get rid of the colors, as most colors still peek through (mostly red, but blue, green, etc. too). The picture's fine otherwise, clean and clear. It just comes off as very warm.

What is causing this? Worn guns?
