My E771 monitor colors suddenly shifted with
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.
