It usually means that either the alignment of the CRT "guns" are off or a magnet (hint: speaker) was stored too close to the display.
Tip: Repair or alignent of said CRT often exceeds what a new CRT will be.
Warning! - LETHAL VOLTAGES ARE INSIDE THAT DISPLAY EVEN WHEN POWER HAS BEEN REMOVED. IF YOU OPEN IT AND DIE, DON'T COMPLAIN TO ME.
I pulled an old computer out of the closet and everything seems to be working fine except the monitor. I got a reddish glow on the right side of my screen. I changed the setting from "optimal" to "70 Hertz" and really screwed things up. I had to go to system restore to fix it but I still got that reddish glow. Does that mean my monitor is going out or is there a fix for it? I don't know what kind of information you need but I'm running Windows ME and it's an Intel(R) 82810 Graphics Controller. Thanks.
