New information!!!! While it's true that the left edge isn't straight with no video present, I know believe that it's just that the phosphor lines aren't vertical. Why? Because I took another look and I realized that ALL the phosphors are illuminated with no video present. I didn't realize this before. WITH video, the left edge is more dramatic because at the top it skips about 4 phosphors before it starts (gradually decreasing until we hit about 60% of the screen height). WITHOUT video all phosphors are illuminated. The left edge still isn't straight as you can see in the photo but it's not as much. Might be that mechanical thing you were talking about. So I thought it mihgt be the game system but I hooked it up to a Sony and it doesn't have that problem. Unless I just can't see it on the Sony due to horizontal overscan not showing it on that TV. ??? Also, the right edge being cut off that I mentioned is also occuring on the Sony so that's moot. Same thing with the hazing -- I think that might just be a composite video artifact. Here it is anyway: versus this lower down but again that happens on the Sony too, although not as much So maybe the slanting is indeed a mechanical cause. Honestly, I can live with the left edge problem if the drooping can be fixed. Maybe adjusting the horizontal position can move the left edge problem away? Please digest this new info and give me your professional opinions!! edit: before you ask, the drooping does NOT occur on the Sony. That's definitely a real problem with the Philips. (I'm calling the original slanting problem "drooping" now to distinguish it from the "left edge" problem, which I'm now calling "left edge problem", since they're both kind of slanting) edit2: Ron - for the left edge problem, #11 MIGHT apply if the right part is hidden by #5. I'm guessing thats a bad idea on my part? None of those pictures seem to have the drooping problem, oddly. Is it a mechanical problem? edit3: Looking at the TV with no-video again I see that the top edge phosphors are also all illuminated and the scanlines themselves seem to be drooping. It kinda looks similar to the left edge in fact! I vote for mechanical issue. (Well, that still doesn't explain the skipped phosphors when video is present though...) Well that's it for me for today. but I'm pretty excited that this can be fixed or at least improved now!
