i have a u5000 that when you turn it on it's mostly red. then after about 5 minutes its magically all better. would it be red transistor on the neck board that causes this?
 
quite possibly.... or a semi shorted gun in the tube..

you may also have something like a cold/cracked solder joint someplace...

I would reflow all the neckboard solder and reseat the neckboard... also check the chassis for cold solder...

id start there and see what you get. DO you happen to have access to a rejuvenator to test the tube?
 
yes i have a rejuvenator but for some reason every tuve shows a bad red gun. even on known good ones. its a test monitor so im not that worried about it. i was just wondering if it was something little or something that was going to cost a arm and a leg.
