I have a Sony 53S65 RPTV and lately I have noticed the convergence is off in the lower right hand side of my screen. Any text there looks bad and it's quite obvious that the convergence is off in that corner. My convergence menu only allows adjustment in the middle of the screen which doesn't really do anything for the lower right side even though it looks great in the middle. My question is, Is it possible to go into some hidden menu on the TV and adjust the convergence for the lower right corner and if so, how difficult is it? IS this something I can handle? I ask this because since it's an older set, I no longer have a warranty and I guess it would be pretty expensive to have someone come in and do it for me. Any help would be greatly appreciated.
