Check the drive voltages at each of the crt cathodes, compare the red with
the other two. do this with the socket attached and removed from the crt.
Trouble shoot the red video drive circuitry before totally condemning the
crt. If a projection set, try swapping the red drive pwb to one of the other
crts and see if the set functions, remove the red crt drive and see if the
set functions. ETC, Good Luck

I have a television with a strange problem. When i start the tv it
takes about 10-15 seconds before the picure appears. And also the red
color is missing, so the piture is bluegreen (but no lines). And then
after about a half minute red fields starts flashing across the
screen, and then it turnes off. Any idea what cause this?

As a test try swapping the drives to the CRT over. If it's the CRT then it
will still flash red, if it's something else it will flash either green or
blue.
