Replaced stk's but I still can't move the red vertically


Did you replace both the convergence ICs ?
The auto-focus won't work properly until BOTH Convergence amps are replaced .
Also you need to replace various resistors along with it .

Convergence problem


Replace the Convergence amplifiers. Mine did the same. It was like watching a 3D movie without the glasses. It is not hard to do for someone who knows their way around a circuit board repair. Otherwise call a reputable service shop.
