No. It just means the phosphor on the inside of the tube is there. It doesn't mean your red gun is working...
Monitor has no red!!

hook the tube up to a rejuvenator, and you will know if your red gun is working or not

Thanks for the offer. I doubt Ill be driving up to chitown with a med res monitor though. My bet would be that drive would be filled with other passengers if I made that trip.
Anyways, what the heck is a rejuvenator.... better yet, where can I get a replacement tube for this 19" WG k7915 chassis? The tube has pretty bad screen burn as it is, wouldnt mind swapping it for one with less.

keep picking up junk 19" tvs. Preferrably early-mid-late 80s and sooner or later youll get one with the correct neck on it. itll be easy to get one fro friends family or craigslist etc.
I dont know if you know much about tube swapping but you will need to keep the purity rings with the donor tube, but remove the yoke and use the wells yoke on your donor tube.
THe black magic trick is marking the purity rings carefully and reinstalling exactly to get good color purity when its all back togther. Getting the yoke converged just right is also kind of tricky.
A rejuvenator is a machine that hooks up to the tube. You can test the hester internal tot he tube as well as testing each gun. WHEn you find wich gun is messed up in the tube, you can attempt a cleaning/balane or a more aggressive "rejuvenation".
It does not always fix bum tubes, but its worth having just for the testing capability.
Ive rejuved over 10 tubes and only had one that simply refused to rejuvenate.
bieng you have some screen burn, a tube swap might be the way to go.
