I know the set's getting a bit long in the tooth at a whole three years old. Anyway, I have a white cross on the set - easily seen against a light background, almost indistinguishable against a dark one. The horizontal one is prominent, but a vertical one shows up now and again. I have had the bezel off before for replacement. Is there something that needs to be adjusted inside the set or is this a software calibration? And if it's hardware inside, can a diligent and knowledgable civilian do it, or do I need to go to a professional? Thanks to any & all with experience with this set. Also, any fantastic tricks or tips for setting the convergence on the set. I've done about all I can with the 9 point internal setup, but it's still marginal at best.
