This is a common problem. Its called a convergence failure.
Problem #1) Convergence
Symptoms:
Problem #2 CRT Fluid has clouded over. Symtoms
You can see some examples and find a fix here...

Replace STK convergence IC's w/OEM or better parts.Senior tech soldering ability needed. Ex==Steel jumper wires feeding b+ to conv. IC's need resolder to prevent call-back.Also, best re-alignment done in service mode==consult service literature.

Your model uses one convergence IC its a STK392-110 you need to replace that IC. You can get a replacement at the following link with free instalation instructions with pictures so you can do the repaair yourself. Here's the link.

Have you checked all of the resistors inthe convergence circuit as well? If not, check them for the correct impedance.. Remember, you have to pull one side of the resistor out of circuit to measure it correctly.
If all of the resistors are good, then you have to do a coarse convergence adjustment on the set through the service menu.. if you need the service manual for the convergence directions, I have one uploaded in the technicians corner of techlore.com

adjust the blue bias on the high voltage block .
it has focus and bias for all three colors
SOURCE: Blue ghosting and can't manually adjust Blue convergence
You will need to replace the convergence IC
