It's possible the gun is going out, but probably not. They all share a
common filament. More likely a problem in the blue output path. The
drivers for the 3 guns are all on the neck board that plugs onto the CRT.
Since they're all the same, it's fairly easy to scope backwards and
compare. Finding the parts is more difficult. 🙁 If you use a greybar
program like VTOT or even just draw some bars in DPAINT you'll have a good
signal on all 3 colors. But since you have to do this with power on the
monitor, it's not for the faint of heart…
