    Hi all,

    First, let me state that I am in no way an authority where this is concerned, so maybe it's the height of stupidity that I should even try. Here's the problem: my HD picture needs a slight adjustment in vertical position (Mitsubishi WS-65511). I have made a few slight adjustments to the color decoding in the service menu before based on an owner's thread that provided the procedure for fixing the red push, but that was about as high level as you can get ("push this button, then advance the number to this using this other button, then push yet another button to save"). I also recorded the original settings just in case.

    Back to my question. I obtained a service manual for this RPTV, with the hopes of finding a setting to adjust the vertical position. I believe it is the V-POS setting under the JNGL function menu, which is currently set to 31 (range 0-63). But when I change the number (with an overscan pattern from DVE displayed), the picture jumps slightly, but does not change position. What am I missing?

    On a side note, the service manual provides the initial settings (factory default?) for everything. I noticed that many settings that have never been touched are currently set differently on my RPTV than in the manual, and there are even additional settings not detailed in the manual at all. Is it possible that changing any one setting affects others? What about changing settings in the user menu (brightness, contrast, etc)... can that effect the settings in the service menu? Maybe an updated version of the manual that reflects a revised firmware?
