Wait everybody! Cannot lose a gun, it's still there impotent caused by external problem! If heater blows you lose all red, green and blue because the heaters (orange glow) is wired in series (like the xmas light string) if any of three heaters opens up, tube won't work, basically toasted. Otherwise if one or more color lost but others still lit that means the wires opened or shorted out or electronic component went poof and all of this are repairable. Monitors loses the one or more colors caused by: 1. bad RAMDAC on video section, swap monitor or try on another 'puter to check. 2. bad connection - wiggle plugs to see and check for any bent pins if cable is permanently attached - replace the cable. 3. bad internal wiring in video cable - if removeable, try another cable or if monitor ha permanent attached video cable replace the cable on the monitor by tech. They fail frequently if flexed too sharply for long time. 4. bad solder joints inside monitor. 5. Dead component(s) in video path inside monitor. 2, 3, 4 and 5 requires tech to repair these. Doesn't have to be apple authorized. A decent monitor repair shop can do this. Sheesh, somebody who have the 700 bux sony monitor send it to repair shop for diagnosis!! If somebody have a monitor w/ colored fog and lines in it can be fixed too. It's shorted gun (in effect turned on full) and needs to be zapped to blow open the short or bypass the short. If you have a very dim monitor that blooms and becomes very blurred if turned up contrast and brightness the tube is at near death. This very dim condition and open heater are only two items means instant junk after correct diagnosis by a monitor tech. I got some more time from a dim hi res Mac monitor by boosting the heater voltage up a bit. But knew this won't last very long.
