Decrypting the Samsung service menu

07-26-2005, 11:01 AM
Hello all,

Just wondering if anyone knew of a link or possibly knew themselves what some of the adjustments in the service menu actually do?

I've done some looking around on the web but haven't found much. I have the Samsung txn3075whf and am trying to fix up a few geometry issues. Here are some examples of settings that I don't really understand:

V Amp
V Shift
H Shift
V Linearity
Upper Linearity
Lower Linearity
H Parabola
Upper Corner
Lower Corner
H Trapezium
V Position
CXA Left Blk
CXA Right Blk

Thanks for any help! I also plan on picking up a calibration disk like Avia.
