Convergence IC's should always be changed out when the
labor is invested to pull the chassis........and use only first
quality OEM parts = no generics,they don't hold up........T.

You might need to adjust the red screen drive control, turn the Red down and see if that clears it out. Sounds like the Red Tube is over driving the Green and blue Tube.
Find the Focus and screen control block there will be 3 controls on Top 3 right under them R-G-B they adjust the Focus to each tube and screen drive for each tube. also you need to clean the lenses off top of each tube they get dirty and dusty and it would help to clean the mirror

Does the magic focus work on your set ?

If it doesn't you must replace the convergence Ic's with a kit that is available through your local parts distributor

You must replace all resistors in the kit
If you are not good at soldering and de- soldering have a local tv shop do it for you

Good luck

One half of picture is distorted


to create the total geometry in the tv is needed a system called Convergence.Convergence amplifiers are damaged in this unit, magic focus cannot work because magic focus works to level computer and controls the amplifiers damaged. this repair is for a technician because an adjustment is needed after the amplifier's replacement.
