I'm familiar with the process of 56 point convergence on the Toshiba 65hdx82 that I've owned for a few years now. BUT!, I can't remember how I toggled between the on/off function of the blue gun! (frustrating). Readings indicate to use the "100" for the red, the "0" for the green and the "Ent" for the blue. the "ent" function isn't doing it for the blue. I know how easy it is to screw things up especially after working on convergence for an hour or so. Input/suggestions? Thanks.
