alignment of picture 82740
Apologies for my lack of avsforum skills, but I can't find what I'm seeking and I'm sure it's here SOMEWHERE!
I have a 82740. I really like the TV for all these years it has served me well, I do not relish the cost of ever having to replace it. I have really only one annoyance, and that's the picture geometry. If I didn't know better I'd never notice, but since I used to install/repair 3-tube CRT projectors I can tell my 82740 needs some adjustment. When I bring up a video game from my PS4 that has uniform content around the edges, I can see my picture is not centered, the right is a bit "taller" than the left, and I have some pretty noticeable pincushioning on the right side.
So, long story short, is there some sort of service or alignment menu I can get in to adjust the projector geometry? I'm sure hoping this is not mechanical mis-alignment such as mirror and such. Any help appreciated!
