I'm having convergence issues that are driving me crazy. I've had my tv for more than a year now, with 300+ hours of usage. However, it does not seem to hold a convergence setting...the convergence appears to drift almost immediately after I set it! I sat down to watch Mission Impossible the other day, and noticed that the picture wasn't as good as I've seen it in the past. The TV had been on for about an hour. "Must be time to tweak the convergence again," I thought. I did the 9-point method, and it took a while since every time I changed one of the 9 points it changed at least one of the other points. But after 10 minutes I had all the crosshairs lining up. Picture looked pretty good (I've previously calibrated the colors using AVIA). About 1/2 hour after doing the 9-point convergence, I decided to check it to see how much it had changed. To my surprise, it was totally out of whack, meaning all 9 points were not converging to various degrees, some points were 5-10 clicks off. I re-did the convergence, and then checked it again immediately. Despite having just lined up with the crosshairs, some of the points were already a few clicks off. Should I even be relying on this 9-point convergence system? That is, just because the crosshairs line up, does that mean I'm reasonably "converged?" Also, I should mention that when I do the touch focus and examine the results with the 9-point menu, it's waaaay off (every point at least a few clicks off). Thus the touch focus method seems absolutely worthless to me. So I guess I have two separate questions: (1) do I even have a prayer of getting reasonable convergence using the non-service-menu options? and (2) Given that my convergence appears to drift so much, so quickly, won't it likely do the same thing once I've completed the 56-point method, making all my hard work futile? I have a 4 year extended warranty on this set. Would constantly-drifting convergence be a valid reason for repair/replacement in your opinion? I really love this set under most circumstances, but I can't deal with adjusting the convergence twice during each movie I watch!
