hi,
i put in two new stacks.the original problem seems to be gone.now my whole screen seems to be out of alignment.i ran the auto convergence several times,with same result.it does go all the way through .it did not finish before.
also the picture looks bent in some areas.my dad said i need a tech to line it up.i do not believe this.i think something else is wrong.the picture used to align itself before all except red,at the bottom it used to have the 3d effect i experienced now all over screen.the bends were there before.any ideas?
