Two weeks ago, I had my lovely Hitachi 43" widescreen RPTV delivered. After flipping through Avia to set it to more reasonable levels (25% contrast, 53% brightness, 38% color, tint 2 clicks toward green, 25% sharpness, all SVM and auto-color turned off) and tweak it all out, I am in love with the picture on this set. When I first got it setup, I checked the geometry/convergence with Avia's patterns and there didn't seem to be any problems. I ran Hitachi's MAGIC FOCUS, it did its automatic convergence, and all was well with the world -- all the lines were white and had no apparent problems. So today, I notice that the upper right corner of the screen looks a little blurry. I hit ye olde' MAGIC FOCUS button, it does its thing and yet I still have a slightly blurred corner. I pop in Avia and put on the convergence test patterns... and sure enough, I now have red edges on horizontal lines and green edges on vertical lines (only in the upper right corner of the screen -- the rest of the screen is dead-on perfect). I know I can do a manual convergence of this set, but would I be risking my warranty by doing it? Does the TV keep track of service menu usage? Should I just take a service call on this one and hope they get it straight? Is it normal for a RPTV to go through something like this during its break-in period? Should I call Hitachi directly or risk calling Circuit City's people? HELP! I'm a RPTV first-timer!
