Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

You have a problem with the three factors, and they are screen voltage, focus voltage, and control (focus 2) voltage. Basically these voltages have to be adjusted since the components in this section have aged some. These controls are usually located in the television on the IHVT (Integrated High Voltage Transformer) or as it is also called the flyback transformer. these controls must be adjusted together, along with the color controls. Here is how the adjustment is done (You will need a schematic diagram, a DC volt meter, and a color bar generator to do these measurments):
1) turn color and tint fully counter clockwise until you have a black and white picture.
2) connect the color bar generator to the TV (ch 3) and turn it on, you should see bars in various shades of gray
3) adjust as best as possible the color and tint controls to obtain the color bars on the screen Red Green Blue.
4) measure the voltages on the focus, screen and control grids of the CRT and match them to the schematic digram measurements.
5) adjust the focus screen and control grids to match the ones on the schematic diagram
6) once this is done then you adjust the color controls once again to obtain the red green and blue bars on the TV screen.
This should help if the CRT (picture tube) electron guns are still good and if the flyback transformer voltage supply is working.
However if you do not have a background in electronics please take the TV to a shop for repairs.
I hope this helps,
