About a month ago, my TW40X81 set was replaced with a 40H80. I am gearing up to do a gambit of adjustments to the set, this weekend. However, there is a problem I am unclear how to correct. I see this problem when watching CNBC, the channel with the stock quotes scrolling across the bottom of the screen. As a given quote approaches the last 3 inches of the left of the screen, it squishes up. Since I own a set of the convergence overlays, I thought I would check out the horizintal linearity. My test source is the Avia "Center Cross" pattern. With the center of the pattern centered to the screen, the problem is real clear. The "over scan" mark on the left side of the pattern is visible, and about 1/2 inch from the edge of the screen. The mark on the right side of the pattern is off the screen about this same distance, 1/2 inch. Thus, the left half of the image is narrower than the right half. The LIN parameter sets the Vertical Linearity, which seems to be the property I'd like to adjust, but on the horizontal access, not the vertical. None of the remaining service mode parameters appear to be the ones I need to correect this. Does anyone have any ideas?
