Possibilities:
1. video-card gone bad;
2. video-cable gone bad;
3. video-cable not tightly-connected to CRT;
4. video-cable not tightly-connected to video-card;
5. "red" gun inside CRT gone bad.

Disconnect the video-cable from the computer, and try again to adjust the "red". If red-free, then it's time to responsibly recycle the CRT.

Reconnect & wiggle the video-cable, to see if that induces any "red" onto the CRT.

Connect the CRT to the VGA-output port on a notebook computer, to see if that video-card generates "red" as one of the primary colours.

Give the CRT a strong "whack" on the side, to see if "red" makes an appearance.

Same problem w yellow on viewsonic pj550


Yellow is the mixture of 100% red and 100% green. what you may have here is a blue LCD failure in the machine. Try this to check. Open up PAINT and double click one of the colors on the bottom. now click add custom color. then in the RGB section put 0 for red 0 for green and 255 for blue. ok out of everything and fill the background w/ the blue. it should be a VERY intense blue, if its white or or kinda blue, you have an LCD issue
