hi I have a Toshiba 50H12, which is a rear projection tv...anyway I got it second hand, and am trying to set it up right.
Problem is I open the service convergence grid, and the blue and green align perfectly, but the red bows in at the center, at the top and bottom, creating a squeezed from the middle effect, as seen below..
Is there a setting in the service menu that would enable me to straighten the red grid up to align with blue and green?
