Well I have suffered a setback. I was finally able to get a somewhat stable picture on the set. I was adjusting the R,G, & B screen and background controls to try to get the color looking better and noticed that the blue never changed. I pulled the chassis out of the cabinet to finish the recapping in the color section and decided to test the CRT again. Now the filament for the blue gun does not light. I tried re-flowing the solder in the filament pins of the base but it makes no difference. So, does anybody know if the filaments in the 21CYP22 are all connected internally or do the individual filaments come out of the glass and connect together at the base pins? If they are connected internally then this tube is now shot.
