Question about Televison & Video
SOURCE: colour issues
Sounds like your red gun may be shorted, Try adjusting the red gun down a little see it that helps.You can also switch the blur CRT socket for the red if your screen is still mostly pink then you know for sure its your red tube that needs replacement. If its mostly blue then you have a problem in the red drive circuit.

This is no solution but a point in a probable direction.
A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

If your picures are all purple it means that the green colour is missing. TV colour is made up by mixing Red, Green & Blue. Removing Green leaving Red & Blue makes purple. Study the green colour circuit for a fault and confirm that the green gun inside the tube is working.
