Does anybody know anything about the Samsung tx-p3075wh service menu info? Like, when you get into it what does everything mean? For instance a couple things are like, H-shift, H-amp, H-par..etc...

Write down all values then start messing with them and see what they do.

H-amp sounds like something you shouldn't mess with. H-par could be correction of parallelogram distortion. SBT and SCT are subbrighness and subcontrast, set those in order to get enough range with the user menu controls (mostly useful on older Samsungs where there was insufficient brightness). PVA is vertical size, VSH and HSH are vert/horz position. The three options beginning with R, G and B are the color controls. That's about as far as i remember.
